NASA’s Parker Solar Probe Achieves Closest Sun Flyby Ever on December 24

NASA's Parker Solar Probe is set to perform its closest flyby of the sun on December 24, 2024, at 6:53 a.m. EST. The spacecraft, which launched in 2018, will approach within 3.8 million miles (6.1 million kilometres) of the solar surface, setting a record for the nearest distance a human-made object has travelled to a star. Travelling at an extraordinary speed of 430,000 mph (692,000 kph), the probe will traverse the sun's corona, collecting data on its high-temperature environment.

Mission Details and Flyby Preparations

The Parker Solar Probe, managed by NASA and designed at the Johns Hopkins Applied Physics Laboratory (JHUAPL), has completed 21 previous solar encounters and seven flybys of Venus, as per a report by Parker Solar Space. The upcoming event marks the 22nd solar approach in its mission to deepen the understanding of the sun's outer atmosphere. According to Nick Pinkine, mission operations manager at JHUAPL, the probe will provide unprecedented data from regions no spacecraft has explored before.

As part of its preparations, the probe sent a final transmission to Earth on December 20, signalling all systems are functioning normally, according to reports. Contact with the spacecraft will remain offline until December 27, when it is expected to send a health status update. Comprehensive science data, including telemetry, will begin to arrive in January 2025, as per reports.

Engineering to Withstand Extreme Temperatures

During the flyby, the spacecraft will endure temperatures reaching 1,800 degrees Fahrenheit (980 degrees Celsius). Its advanced heat shield, constructed from carbon foam, ensures the probe's instruments remain at near room temperature while withstanding up to 1,377 degrees Celsius.

Future of the Mission

As per reports, two additional close solar flybys are planned for March 22 and June 19, 2025. Decisions regarding the spacecraft's trajectory and continued operations are expected after the primary mission concludes. The Parker Solar Probe's findings aim to address critical questions about the sun's behaviour, contributing to the broader understanding of solar phenomena.

Apple Developing Smart Home Doorbell With Support for FaceID and Third-Party Locks: Report

Apple will delve into the smart home market as it looks for new growth opportunities next year, according to a report. As part of its efforts, the Cupertino-based technology giant is said to be developing a smart home doorbell that will have FaceID support, enabling users to scan their face to gain entry, much like the iPhone. For enhanced functionality of the purported device, Apple may turn to other third-party smart lock makers or even tie up with a single specific company.

Apple Smart Doorbell

In the latest edition of the Power On newsletter, Bloomberg's Mark Gurman detailed Apple's smart home efforts. The iPhone maker is reported to be working on a smart home doorbell system that will have advanced facial recognition, which wirelessly connects to a deadbolt lock.

Apple already offers several third-party smart home locks on its online store but this is said to be its first-ever proprietary offering. It is speculated to work on the same HomeKit protocol and may support other third-party locks. With this move, the company may surface as a competitor in a space dominated by the likes of Amazon's Ring and Google Nest.

The product is expected to use Apple's first-ever proprietary wireless networking chipset dubbed Proxima to protect consumer data. The smart home doorbell system is not expected to hit the market at least until the end of next year. However, there may be a possibility that Apple develops the technology but sells it through a third-party brand. If that is the case, Logitech or Belkin are to be the likely partners, as per Gurman.

Other Smart Home Products

The newsletter also details other endeavours by the iPhone maker in the smart home space. It is said to be developing a smart hub powered by artificial intelligence (AI) which would feature a 6-inch screen, FaceTime support, and a new operating system. Apple is also reported to be roll out upgrades for Apple TV and HomePod mini devices next year — both having the new wireless networking chip.

The company could also delve into the home security space with a purported in-home security camera that would work in tandem with its purported smart hub. Its development is already reported to be underway and may offer competition to the likes of Amazon, Blink, Google, and Logitech.

SOL Price Prediction; New Gem on the Block Aims to Eclipse Polkadot—Is Solana Next?

SOL price predictions remain bullish even in the middle of a market-wide sell-off following the move by the Federal Reserve to halt rate cuts in 2025. Solana's price is already forming a bull flag even as SOL dips below $200 in a move that analysts anticipate could lead to a bullish breakout past the $210 mark.

Some SOL price predictions forecast lower lows for SOL, especially if SOL's price continues to dip below $190. Polkadot's DOT is also on a major pullback, with its price hovering around $7 after surging all the way to $11.66 at the start of December.

SOL price predictions and DOT aside, the best new crypto to invest in right now is Lunex Network. After its presale gained momentum, Lunex's LNEX token surged over 250% and is now priced at $0.0046 in a presale that has so far raised over $5.3 million. Can LNEX surpass its ATH?

Lunex Network is on track to be the best new crypto this bull run

A market-wide correction was expected, especially after the meteoric rally of Bitcoin and cryptocurrencies. If you are looking for a bargain, however, the best new crypto to jump into is Lunex's LNEX token, which is pioneering the world's first multi-chain DEX and aggregator.

The world of DEXs is often plagued by platforms that are slow to execute trades, and with the fast-paced nature of cryptocurrencies, a delayed trade can lead to massive losses. Most traders on DEXs have to contend with sniper bots, front running, and high slippage. What's more, trading on-chain can often lead to tapping into low-liquidity pairs.

Lunex offers a hybrid model that combines the best of both centralized and decentralized exchanges. Thanks to Lunex's aggregator, every trade is executed with the most affordable network fees and with the most liquidity. This approach is not only secure but fast and comes with zero slippage.

SOL price predictions set bullish targets despite market dip

Solana has had a wild ride in 2024, with its price surging all the way to a new all-time high of $269. That is a 239% uptick that saw most onlookers set bullish SOL price predictions. While SOL's price is rebounding, there is still a likelihood for lower lows even as Solana's ecosystem flips Ethereum in terms of dev growth. Apart from a growth in developers, Solana is also receiving increased institutional adoption as its network's daily active addresses surge by 30%.

Polkadot (DOT) dips below the 0.5 Fibonacci Retracement

While the entire crypto market is in a downturn following the news from the Federal Reserve, Polkadot's DOT seems to have been hit the most, with its price falling 41% to lows of $6.86. Polkdot champions interoperability and has attracted Harbour and Velocity Labs to launch a stablecoin on its open-source network. While this new development could be bullish for DOT, it remains to be seen whether DOT's price will rebound.

Conclusion

Market corrections are normal in any bull market, and bullish SOL price predictions could still materialize. However, while the likes of DOT languish, Lunex's LNEX token is emerging as the best new crypto this bull run thanks to its capacity to deliver institutional-grade liquidity to DEXs.

Samsung Galaxy S25 Slim Specifications Leaked; Might Be Thicker Than iPhone 17 Air

Samsung Galaxy S25 Slim is tipped to debut next year as the thinnest flagship-grade smartphone from the company in years, and details of the purported handset's specifications have been leaked by a tipster. The handset could be launched in the second quarter of 2025, which is when the company usually launches its Galaxy A series and Fan Edition (FE) smartphones. Meanwhile, a Chinese leaker has also revealed that the Samsung Galaxy S25 Slim might be thicker than the iPhone 17 Air, which is also tipped to debut next year.

Samsung Galaxy S25 Slim Tipped to Debut in Q2 2025

According to details posted to X (formerly Twitter) by Debayan Roy (@Gadgetsdata) on Friday, the Samsung Galaxy S25 Slim will sport a 6.6-inch screen. If this claim is accurate, it means the company could equip the handset with the same display as the Galaxy S25+ model, which is expected to debut alongside the standard Galaxy S25 and Galaxy S25 Ultra model in January 2025.

Galaxy S25 Slim (SM-S937x/DS) :

• 6.66" display (like S25+)

• 200MP HP5 main camera
• 50MP JN5 UW
• 50MP JN5 3.5X telephoto

• SD 8 Elite
• ~4700mAh - 5000mAh?

Launching in Q2, 2025 - similar to A & FE series launch timeline.

— Debayan Roy (Gadgetsdata) (@Gadgetsdata) December 20, 2024

The tipster also states that the Galaxy S25 Slim will be powered by a Snapdragon 8 Elite chip, which was unveiled by Qualcomm in October. It is also said to pack a large battery, considering its slim form factor — the Galaxy S25 Slim might include a battery with a capacity that ranges between 4,700mAh and 5,000mAh.

Unlike the iPhone 17 Air, which is tipped to arrive with only one rear camera, the Galaxy S25 Slim model could feature a triple rear camera setup, according to Roy's post on X. The handset will be equipped with a 200-megapixel primary camera with an ISOCELL HP5 sensor, and two 50-megapixel cameras with ISOCELL JN5 sensors for ultrawide and telephoto (3.5x optical zoom) photography.

Meanwhile, the Samsung Galaxy S25 could measure less than 7mm in thickness, tipster Ice Universe claims in a post on Weibo, the Chinese microblogging website (via GSMArena). This is thicker than the purported iPhone 17 Air, which is expected to launch in the second half of 2025.

Samsung could launch the Galaxy S25 Slim in Q2 2025, according to Roy — this is around the same time that it usually introduces its Galaxy A series or Galaxy FE smartphones. The company is reportedly gearing up to launch the successors to the Galaxy S24, Galaxy S24+ and Galaxy S24 Ultra at a Galaxy Unpacked launch event next month.

OpenAI Unveils 'o3' Reasoning AI Models in Test Phase

OpenAI said on Friday it was testing new reasoning AI models, o3 and o3 mini, in a sign of growing competition with rivals such as Google to create smarter models capable of tackling complex problems.

CEO Sam Altman said the AI startup plans to launch o3 mini by the end of January, and full o3 after that, as more robust large language models could outperform existing models and attract new investments and users.

Microsoft-backed OpenAI released o1 AI models in September designed to spend more time processing queries to solve hard problems.

The o1 models are capable of reasoning through complex tasks and can solve more challenging problems than previous models in science, coding and math, the AI firm had said in a blog post.

OpenAI's new o3 and o3 mini models, which are in internal safety testing currently, will be more powerful than its previously launched o1 models, the company said.

The GenAI pioneer said it was opening up an application process for external researchers to test o3 models ahead of the public release, which will close on Jan. 10.

OpenAI had triggered an AI arms race after it launched ChatGPT in November 2022. The growing popularity of the company and new product launches helped OpenAI in closing a $6.6 billion funding round in October.

Rival Alphabet's Google released the second generation of its AI model Gemini earlier in December, as the search giant aims to reclaim the lead in the AI technology race.

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals

The innermost planet of the TRAPPIST-1 system, TRAPPIST-1b, may possess a carbon dioxide-rich atmosphere, according to research published in Nature Astronomy on December 16. The TRAPPIST-1 system, which lies 40 light-years from Earth and includes seven Earth-sized exoplanets, has intrigued astronomers since its discovery in 2017. Earlier studies suggested that these planets lacked atmospheres due to intense stellar radiation. However, recent data from the James Webb Space Telescope (JWST) raises the possibility of a hazy, carbon dioxide-heavy atmosphere on TRAPPIST-1b.

Findings on Atmospheric Composition

As per reports, the study highlights new measurements taken at 12.8 micrometres, showing evidence of a reflective haze in TRAPPIST-1b's upper atmosphere. Researchers believe this haze may cause upper layers to emit rather than absorb radiation, challenging previous assumptions. Speaking to KU Leuven News, Leen Decin, co-author of the study and researcher at KU Leuven in Belgium, noted, that the two data points for TRAPPIST-1b allows them to explore various scenarios for its atmosphere, whether it exists or not.

Volcanism and Surface Conditions

The research also indicates elevated surface temperatures, suggesting potential volcanic activity. Similar dynamics have been observed on Saturn's moon Titan. According to Michiel Min from the SRON Netherlands Institute for Space Research, who contributed to the study, in a statement, the atmospheric chemistry of TRAPPIST-1b is expected to be unlike anything seen on Titan or in the solar system.

Ongoing Studies

The team aims to examine heat distribution across the planet's surface to determine whether an atmosphere is present. Michaël Gillon, an astronomer at the University of Liège who led the discovery of the TRAPPIST-1 system, explained to Nature Astronomy that an atmosphere would facilitate heat redistribution from the day to night side of the planet. Without it, heat transfer would be minimal.
These findings may reshape understanding of atmospheres around exoplanets near red dwarf stars, according to experts.

Scientists Develop New Approach to Capture Gravitational Wave Memory from Supernovae

A study published in Physical Review Letters explores a new approach to detecting the gravitational wave memory effect, a phenomenon predicted by Einstein's general relativity. This effect refers to the permanent alteration in the distance between cosmic objects caused by a passing gravitational wave. Scientists suggest that existing gravitational wave observatories could capture this elusive signature, specifically from core-collapse supernovae (CCSN), which occur when massive stars over ten times the Sun's mass collapse and explode.

Core-collapse supernovae generate gravitational waves with unique characteristics due to their changing quadrupole moments during collapse. According to reports, while the amplitude of these waves is lower compared to signals from black hole or neutron star mergers, they provide critical insights into stellar interiors. Unlike electromagnetic signals, which originate from a supernova's surface, gravitational waves emerge from deep within, offering a rare glimpse into the dynamics of a collapsing star.

Challenges of Detecting Supernova Gravitational Waves

Detection of gravitational waves from CCSN has proven difficult due to their lower amplitudes, shorter durations, and complex signatures. Reports state that these waves fall below the sensitivity range of current high-frequency detectors such as advanced LIGO. However, the study indicates that low-frequency gravitational waves from CCSN exhibit a "memory" effect. This effect arises from anisotropic neutrino emissions and matter movement during collapse, leaving a non-zero gravitational disturbance.

As per reports, the research team, led by Colter J. Richardson from the University of Tennessee, analysed three-dimensional simulations of non-rotating CCSN with masses up to 25 solar masses using the CHIMERA model. Their findings revealed a distinct ramp-up in gravitational wave signals characteristic of memory with matched filtering techniques, the team concluded that signals from a 25 solar mass supernova could be detected up to 10 kiloparsecs away, a range accessible by existing observatories.

Potential for Future Research

Richardson highlighted, as per sources, the significance of exploring low-frequency gravitational waves and encouraged further investigations using the study's methodology. Future research may focus on common merger events or improvements in detector sensitivity to refine the detection of memory signals.

NASA's retired InSight Mars lander was recently spotted by the Mars Reconnaissance Orbiter (MRO) in an image taken on October 23, 2024, using its High-Resolution Imaging Science Experiment (HiRISE) camera. The image shows dust build-up on the lander's solar panels, which now match the reddish-brown colour of the Martian surface. Reports suggest this observation continues to provide insights into the movement of dust and wind patterns on Mars.

InSight's Mission and Retirement

The InSight lander, which touched down in November 2018, was central to detecting Marsquakes and studying the planet's crust, mantle, and core. NASA officially ended the mission in December 2022 after the lander stopped communicating due to excessive dust accumulation on its solar panels. Engineers from NASA's Jet Propulsion Laboratory (JPL) in California continued to monitor the lander for any signs of reactivation, hoping Martian winds might clear its panels. However, as per reports, no signals have been received, and listening operations will conclude by the end of this year.

Tracking Dust Movement

The new HiRISE images were captured to monitor how dust and wind alter the Martian surface over time. Ingrid Daubar, a science team member at Brown University, told sources that the images of InSight's location offer crucial data on how dust accumulates and shifts. This information helps researchers understand the Martian dust cycle and wind dynamics, which are vital for future missions.

Surface Changes and Impact Studies

Dust movement not only impacts solar-powered missions but also helps scientists study surface ageing processes. Blast marks left by InSight's landing thrusters, once dark and prominent in 2018, have faded significantly, indicating dust deposition over time. This phenomenon also aids researchers in estimating the age of craters and surface features, as dust gradually erodes their visibility.

Ongoing Role of Mars Reconnaissance Orbiter

The Mars Reconnaissance Orbiter continues to play a key role in observing Mars' surface changes. It monitors both active missions, such as the Perseverance and Curiosity rovers, and inactive ones, including Spirit, Opportunity, and the Phoenix lander. Managed by JPL for NASA's Science Mission Directorate, the orbiter's HiRISE camera remains a vital tool for long-term studies of the Martian environment.

iPhone 17 Air to Be Priced Below Pro Models; Apple to Launch Foldable iPhone in 2026: Report

iPhone 17 series is expected to hit the market in Fall 2025. Apple's next-generation iPhone lineup is speculated to feature a new model in addition to the standard variants in the form of the iPhone 17 Air — a new handset with a slimmer profile and toned-down features. Now, a report suggests that this purported smartphone may be priced lower than the iPhone 17 Pro models. However, Apple may cut down on a marquee iPhone feature on its slim phone to achieve the same. Further, the Cupertino, California-based technology giant is developing two foldable devices with a targeted release in 2026.

iPhone 17 Air

According to a Wall Street Journal report, the iPhone 17 Air is aimed at reviving growth at the company. In recent years, the iPhone maker has offered incremental upgrades, but its purported Air model could be the first new iPhone introduced in the market since the iPhone 14 Plus in 2022.

As the name suggests, the iPhone 17 Air is reported to be thinner than the approximately 8-millimetre profile of the current models. The report claimed that the new iPhone model would be equipped with a simplified camera system in a bid to keep costs low. The iPhone camera system is a marquee feature on Apple's smartphones, but the report suggested that cutting down on camera capabilities might enable the company to place the iPhone 17 Air below the Pro models in terms of pricing. Presently, an expanded camera system is one of the most prominent features that separates Pro and base iPhone models.

The new claim corroborates previous leaks that suggest the purported handset could feature a single rear camera with a 48-megapixel sensor, while also including the 2x telephoto functions of the current iPhone 16. And while the exact dimensions of the iPhone 17 Air were not revealed, reports suggested that Apple could launch the iPhone 17 Air with a thickness of 6mm.

Foldable iPhone Models

The WSJ report further claimed that Apple had two foldable devices in development — a foldable iPhone and a larger laptop replacement. The former is speculated to come with a bigger display than the iPhone 16 Pro Max. Meanwhile, the foldable laptop might be equipped with a 19-inch screen when unfolded.

While both products have been in development for years, Apple is said to be facing numerous challenges related to the display cover and hinge mechanism. The report revealed the company had experimented with several iPhone designs over the years, such as a device with an outward-facing display when folded. However, Apple has reportedly finally settled on the traditional foldable smartphone design with an inward-facing screen.

Citing people familiar with the matter, WSJ reported that Apple executives were planning a 2026 release for the foldable devices but might delay the launch by up to a year to address any potential challenges.

Mathematician Solves Decades-Old Sofa Problem with New Findings

A long-standing mathematical puzzle known as the "sofa problem," posed in 1966 by Austrian-Canadian mathematician Leo Moser, may have finally been solved. The problem involves determining the maximum area of a single, planar shape that can navigate a right-angled corner in a hallway of unit width. This question, despite its seemingly simple premise, has confounded mathematicians for over half a century.

Jineon Baek, a postdoctoral researcher in mathematics at Yonsei University in South Korea, has reportedly proposed a solution. According to a study shared on the preprint website ArXiv on December 2, Baek demonstrated that the maximum area of the hypothetical sofa is 2.2195 units. This value refines the previously established range of 2.2195 to 2.37 units. While the proof awaits peer review, experts are expected to verify its accuracy.

Origins and Prior Developments

The problem was initially conceptualised by Leo Moser and progress was made in 1992 when Joseph Gerver, an emeritus professor at Rutgers University, proposed a U-shaped solution comprising 18 curves. Gerver's calculations suggested the lower bound of 2.2195 units for the sofa's area. Disputes persisted over whether a larger sofa could exist, with a 2018 computer-assisted analysis suggesting an upper bound of 2.37 units.

Key Insights from Baek's Proof

Baek's findings reportedly confirm that Gerver's solution represents the optimal configuration. By meticulously analyzing the geometry and movement of the shape, Baek demonstrated that the U-shaped design could achieve the maximum possible area for navigating the corner.

While the study has yet to be published in a peer-reviewed journal, the mathematical community has shown significant interest. Images of the "Gerver sofa" circulated on social media following Baek's announcement, sparking discussions about the implications of this long-awaited resolution.

This breakthrough is anticipated to close the chapter on one of mathematics' enduring conundrums, pending independent verification of Baek's work.

Earth’s Inner Core Might Be Slowing Down and Changing Shape, New Study Reveals

Research indicates that Earth's solid inner core, a metal sphere encased within the molten outer core, could be undergoing changes in both rotation and surface structure. Studies involving seismic waves from earthquakes have revealed that the core's rotation may have slowed, paused or even reversed relative to Earth's surface approximately 15 years ago. New findings presented by John Vidale, a geophysicist at the University of Southern California, during a meeting of the American Geophysical Union suggest that additional changes to the inner core's surface could also be occurring.

Earthquake Waves Reveal Inner Core Dynamics

Insights into the inner core rely on seismic waves generated by earthquakes, as no instrument can directly access Earth's core. According to reports, geophysicists often examine seismic waves originating from the South Sandwich Islands near Antarctica. These waves traverse the Earth, passing through its layers and arriving at recording stations such as those in Alaska. Waveform discrepancies between similar earthquakes occurring at different times indicate changes within the inner core.

Surface Changes and Deformation Hypotheses

Reportedly, Vidale and his team analysed seismic data from around 200 earthquake pairs recorded between 1991 and 2024. Discrepancies in waveforms were observed in recordings from Yellowknife, Canada but not from Fairbanks, Alaska. Vidale attributed these differences to possible deformation of the inner core's outer surface. According to reports, the entire core might be subtly reshaping or localised regions could be swelling or contracting. These changes might be influenced by gravitational interactions with the mantle or material flow within the outer core.

Diverse Perspectives on Core Behavior

The interpretations remain debated. Lianxing Wen, a geophysicist from Stony Brook University, has suggested in a statement that surface changes alone, without rotational differences, might explain these observations. Meanwhile, Xiaodong Song of Peking University emphasised in his statement that both rotational and surface changes could be contributing factors.

Current findings remain limited in their implications for Earth's surface, as stated in reports. Until further research clarifies the processes, the potential impact remains uncertain.

WhatsApp Rolls Out New Effects for Video Calls, Group Calling Improvements

WhatsApp is rolling out several new features to improve the audio and video calling experience on desktop and mobile platforms ahead of the holiday season, the company announced on Thursday. The social media platform now lets users pick from even more effects in video calls. Further, it adds the ability to select specific participants for calls in group chats. WhatsApp also claims to improve the calling experience by introducing higher-resolution video.

WhatsApp Adds 10 Effects for Video Calls

In a blog post, WhatsApp detailed the new features on desktop and mobile platforms. The company highlighted that users can now pick from 10 effects in video calls, including puppy ears, underwater, and a karaoke microphone. In group chats, users can select specific participants for calls without disrupting the entire chat.

The social media platform says that it brings more options to the Calls tab on the WhatsApp desktop app. There are now options for starting a call, creating a call link, and dialling a number. It also introduces higher-resolution video calling with a clearer picture in individual as well as group calls.

Notably, these features add to the recent introductions on WhatsApp in recent months.

WhatsApp previously introduced typing indicators for real-time engagement in chats earlier this month. Visual cues appear in chats along with the profile picture of the user who's typing when they are engaged in active conversations in both one-to-one and group chats. The feature is claimed to be particularly useful when multiple users are typing simultaneously in group chats.

Further, it also rolled out voice message transcripts last month. This is said to make sending voice messages a more convenient process. The feature provides users with a text-based transcription of the voice message received from others. However, only the recipient can see a transcript of the voice message and not the sender. WhatsApp emphasises that transcripts are generated on-device and no one else can hear or read its content.

Mars Dust Storms May Be Predictable Based on Surface Heating Patterns

New research has indicated a strong connection between warm, sunny days on Mars and the occurrence of dust storms, with nearly 78 percent of storms preceded by increased solar heating, according to a study presented at the annual meeting of the American Geophysical Union in Washington, D.C. The study, led by Heshani Pieris and Paul Hayne of the University of Colorado, Boulder, analysed data from NASA's Mars Reconnaissance Orbiter, revealing patterns that could help predict these atmospheric phenomena.

Insights into Dust Storm Patterns

The researchers investigated data spanning eight Martian years—approximately 15 Earth years—collected by the Mars Climate Sounder instrument. Observations focused on two types of dust storms, categorised as "A" and "C" storms, which primarily originate in the planet's northern hemisphere and travel through Acidalia Planitia and Utopia Planitia. The study found a direct correlation between prolonged surface heating and the emergence of these storms.

In a statement, Pieris highlighted the significant impact dust storms have on Mars missions, noting their tendency to coat solar panels with fine particles, which can disrupt operations. This was exemplified by NASA's Opportunity rover, which was rendered inoperable during a global dust storm.

Potential for Forecasting Dust Storms

Pieris and Hayne's research suggests the possibility of predicting Martian dust storms based on patterns of surface heating. An algorithm developed during the study has shown a 64% confidence level in forecasting "A" and "C" storms, offering a potential tool for managing the risks posed to future crewed missions.

While the study marks progress, as per reports, Hayne pointed out that fundamental questions about dust storm formation remain unanswered, including the factors that allow localised storms to grow into global events. Data from NASA's deactivated Mars Global Surveyor supports the findings, showing that imbalances in solar energy absorption during warmer periods can fuel storm activity.

iOS 18.2 for iPhone With Image Playground and More Apple Intelligence Features Rolls Out: What’s New

Apple rolled out the iOS 18.2 update for iPhone globally on Wednesday. It arrives a day after the release of iOS 18.2 Release Candidate (RC) 2, expanding the set of Apple Intelligence features that the Cupertino-based technology giant previously introduced. Its latest update brings Image Playground, Genmoji, and ChatGPT integration. It also bundles a new visual lookup feature exclusive to the iPhone 16 series while expanding the availability of Apple's artificial intelligence (AI) suite to more languages.

iOS 18.2 Compatible Models

Apple says all iPhone models compatible with the initial iOS 18 update are eligible to download the latest iOS 18.2 update. However, the Apple Intelligence features are limited to the iPhone 16 lineup, iPhone 15 Pro, and iPhone 15 Pro Max.

It is being expanded to more English-speaking locales such as Australia, Canada, Ireland, New Zealand, South Africa, and the UK. The AI suite is available globally on the iPhone except for China and the EU, but it will introduced in the latter starting April next year.

iOS 18.2 Update Features

In a newsroom post, Apple detailed the new features arriving on the iPhone with the iOS 18.2 update. One of the highlights is Image Playground — a new standalone app that bundles three capabilities and brings more ways for users to express themselves better. It leverages generative AI to generate images in distinct styles such as animation or illustration, based on textual prompts. Then there's Genmoji, which has similar functionality but works for emojis. The created images and emojis can be shared in apps such as Messages, Notes, and Keynote, as per Apple.

Meanwhile, Image Wand transforms a rough sketch into a related image in the Notes app, similar to Samsung's AI-powered Sketch to Image feature. It can also create an image in the app based on the handwritten or typed text using on-device generative AI models.

While Apple introduced Writing Tools with iOS 18.1 in October, the latest iOS 18.2 update expands their capabilities. It brings a new Describe Your Change option which enables users to specify the changes they'd like, such as making it more dynamic or rewrite it in the form of a poem. It joins the existing Rewrite, Proofread, and Summarise tools and is available system-wide and in third-party apps.

iPhone 16 series users can now take advantage of the new Visual Intelligence feature. Apple says it is a visual lookup tool which helps them learn about objects and places instantly, leveraging the new Camera Control button. It can summarise and copy text, translate it between languages, and detect phone numbers or email addresses with the option to add to contacts. It also allows them to search Google for a product they like, solve a math equation, or simply ask ChatGPT to provide more information.

And on a related note, ChatGPT comes to the iPhone. Siri, which is Apple's voice assistant, can now leverage the capabilities of OpenAI's AI chatbot to provide users with more in-depth responses to queries and document and image-understanding capabilities. Siri can suggest a user access to ChatGPT for certain requests and provide direct answers. Further, it can also generate content using native writing tools. Apple says this feature requires optional sign-in, and iPhone users with a paid ChatGPT account can use their account for access to more powerful OpenAI models.

The company emphasises that OpenAI does not store requests, nor does it use the data for training its models. It also obscures their IP addresses to prevent sessions from being linked together.

What's Ahead

Apple Intelligence capabilities will be expanded further in the coming months, as per Apple. Siri will get contextual awareness to deliver tailored responses. It is also claimed to be able to have on-screen awareness with new actions across Apple and third-party apps. Other expected features include Priority Notifications and a new sketch style for Image Playground.
