James Webb Telescope captures earliest ever galaxy seen yet
27 May 2025 11:35
WASHINGTON (AGENCIES) Astronomers announced that they were able to observe the earliest galaxy ever seen – MoM-z14, which was discovered as part of the Mirage or Miracle study.Using NASA's James Webb Space Telescope (JWST), scientists were able to confirm that the light they captured was emitted just 280 million years after the Big Bang. For context, the Big Bang is thought to have occurred 13.8 billion years ago.The JWST is Earth's most advanced infrared space telescope capable of capturing images of some of the most distant galaxies. These galaxies experience severe redshifts – a phenomenon where the wavelength of light is stretched because of distance, shifting it towards the red part of the colour spectrum.Patterns seen in MoM-z14 are also common among the most ancient stars born in the Milky Way. According to the researchers, this suggests that they were witnessing the formation of similar stars in dense clusters.Using various methods, scientists were able to determine that the galaxy is an extremely compact star-forming galaxy and could rank among the most nitrogen-enhanced sources discovered with the JWST yet.
Since its launch in late 2021, the JWST has provided humanity with information from the deepest depths of the universe.

Scientists discover unusual atmospheric motion on Saturn's largest moon
7 June 2025 09:52 ABU DHABI (ALETIHAD)Scientists at the University of Bristol, UK have observed a strange phenomenon in the atmosphere of Titan, Saturn's largest moon, discovering that its upper atmospheric layers do not remain fixed relative to the surface but instead wobble with the changing seasons.A research team made the discovery after analysing 13 years' worth of infrared data from the Cassini-Huygens mission, a joint venture between NASA, the European Space Agency (ESA), and the Italian Space is the only moon in the Solar System with a significant atmosphere, and one that has long captivated planetary scientists.'The behaviour of Titan's atmospheric tilt is very strange!' said Lucy Wright, lead author and postdoctoral researcher at Bristol's School of Earth Sciences. 'Titan's atmosphere appears to be acting like a gyroscope, stabilising itself in space.'We think some event in the past may have knocked the atmosphere off its spin axis, causing it to wobble. Even more intriguingly, we've found that the size of this tilt changes with Titan's seasons.'The team studied the symmetry of Titan's atmospheric temperature field and found that it isn't centred exactly on the pole, as expected. Instead, it shifts over time, in step with Titan's long seasonal cycle—each year on Titan lasts nearly 30 years on Nick Teanby, co-author and planetary scientist at Bristol said: 'What's puzzling is how the tilt direction remains fixed in space, rather than being influenced by the Sun or Saturn.'That would've given us clues to the cause. Instead, we've got a new mystery on our hands.'This discovery will impact NASA's upcoming Dragonfly mission, a drone-like rotorcraft scheduled to arrive at Titan in the 2030s. As Dragonfly descends through the atmosphere, it will be carried by Titan's fast-moving winds—winds that are about 20 times faster than the rotation of the how the atmosphere wobbles with the seasons is crucial for calculating the landing trajectory of Conor Nixon, planetary scientist at NASA Goddard and co-author of the study, added: 'Our work shows that there are still remarkable discoveries to be made in Cassini's archive. This instrument, partly built in the UK, journeyed across the Solar System and continues to give us valuable scientific returns. 'The fact that Titan's atmosphere behaves like a spinning top disconnected from its surface raises fascinating questions—not just for Titan, but for understanding atmospheric physics more broadly, including on Earth.' The team's findings contribute to a growing body of research suggesting Titan is not just Earth-like in appearance but an alien world with climate systems all its own, and many secrets still hidden beneath its golden haze.

SpaceX set for next Starship launch after fiery failure
A launch window opens at 6:30 pm (2330 GMT) from the company's Starbase facility near a southern Texas village that recently voted to become a city, also called Starbase. Standing 403 feet (123 meters) tall, Starship is the largest and most powerful launch vehicle ever built, and it carries Musk's hopes of making humanity a multi-planetary species. NASA is also counting on a variant of Starship to serve as the crew lander for Artemis 3, the mission to return Americans to the Moon. But the last two tests ended with the upper stages erupting into fiery cascades that sent debris raining down over Caribbean islands and disrupting flights -- piling more pressure onto SpaceX to get it right this time. The company is betting that its aggressive testing approach, which helped it become the dominant force in commercial spaceflight, will once again pay off. Still, it acknowledged in a statement that progress "won't always come in leaps." According to the Wall Street Journal, SpaceX is shifting personnel and resources to the Starship program in a push to have the vehicle ready for a Mars mission as soon as next year.

Huge planet discovered orbiting tiny star puzzles scientists
4 June 2025 17:56 PARIS (AFP)Astronomers announced Wednesday they have discovered a massive planet orbiting a tiny star, a bizarre pairing that has stumped of the stars across the Milky Way are small red dwarfs like TOI-6894, which has only 20 percent the mass of our had not been thought possible that such puny, weak stars could provide the conditions needed to form and host huge an international team of astronomers have detected the unmistakable signature of a gas giant planet orbiting the undersized TOI-6894, according to a study in the journal Nature makes the star the smallest star yet known to host a gas planet has a slightly larger radius than Saturn, but only half its mass. It orbits its star in a little over three astronomers discovered the planet when searching through more than 91,000 low-mass red dwarfs observed by NASA's TESS space existence was then confirmed by ground-based telescopes, including Chile's Very Large Telescope."The fact that this star hosts a giant planet has big implications for the total number of giant planets we estimate exist in our galaxy," study co-author Daniel Bayliss of the UK's Warwick University said in a co-author, Vincent Van Eylen, of University College London, said it was an "intriguing discovery"."We don't really understand how a star with so little mass can form such a massive planet!" he said."This is one of the goals of the search for more exoplanets. By finding planetary systems different from our solar system, we can test our models and better understand how our own solar system formed."The most prominent theory for how planets form is called core process begins when a ring of gas and dust -- called a protoplanetary disc -- which surrounds a newly formed star builds up into a planetary core. This core attracts more gas that forms an atmosphere, eventually snowballing into a gas this theory, it is difficult for low-mass stars to host giant planets because there is not enough gas and dust to begin building a core in the first place.A rival theory proposes that these planets instead form when their protoplanetary disc becomes gravitationally unstable and breaks up, with the collapsing gas and dust forming a neither theory seems to explain the existence of the newly discovered planet, TOI-6894b, the researchers planet also interests scientists because it is strangely of the gas giants discovered outside our Solar System so far have been what are known as "hot Jupiters", where temperatures soar well over 1,000 degrees the newly discovered planet appears to be under 150C, the researchers said."Temperatures are low enough that atmospheric observations could even show us ammonia, which would be the first time it is found in an exoplanet atmosphere," said study co-author Amaury Triaud of Birmingham University. The James Webb space telescope is scheduled to turn its powerful gaze towards the planet in the next year, which could help uncover some more mysteries of this strange planet.
