James Webb Helps Astronomers Chart the Universe’s Hidden Dark Matter
Astronomers have created the sharpest map yet of dark matter using deep observations from NASA’s James Webb Space Telescope. By analysing the gravitational distortion of hundreds of thousands of distant galaxies, the team traced invisible dark matter across a large region of the sky. The results confirm that dark matter forms the scaffolding arou...

Rare Interstellar Object 3I/ATLAS Fails Alien Test, Scientists Say
The most sensitive radio search ever conducted on interstellar object 3I/ATLAS has found no signs of alien technology. Using the Green Bank Telescope, scientists scanned key radio bands during its closest approach to Earth. All detected signals were linked to interference, strengthening the view that 3I/ATLAS is a natural object.

NASA’s Chandra Spots Champagne Cluster Formed by a Massive Galaxy Collision
Discovered on New Year’s Eve 2020, the Champagne Cluster is a striking pair of colliding galaxy clusters revealed through combined X-ray and optical observations. NASA’s Chandra X-ray Observatory shows superheated gas stretched and distorted, exposing a massive cosmic collision hidden from visible light alone. Studied by UC Davis astronomers, t...

NASA Confirms Third Interstellar Visitor 3I/ATLAS Is a Natural Comet
NASA has confirmed that interstellar object 3I/ATLAS is a natural comet, not alien technology. The comet shows unusual carbon-dioxide and nickel vapours, offering a rare look at ancient material from another star. Its path is safe, staying about 1.8 AU from Earth during its Solar System passage.

NASA’s Nancy Grace Roman Space Telescope Surpassing Expectations Even Before Launch, Reveals Research
NASA’s upcoming Roman Space Telescope is expected to measure seismic waves in over 300,000 red giant stars, far greater than early predictions. These signals will help scientists better understand exoplanet systems and the Milky Way’s ancient core. Researchers say Roman’s natural survey design enables this breakthrough even before the telesco...

Interstellar Comet 3I/ATLAS Photographed Beside Distant Galaxy in Rare Cosmic Shot
A new image of interstellar comet 3I/ATLAS captures its glowing tails and a distant barred spiral galaxy, creating a dramatic cosmic overlap. Astronomers say the comet’s unusual features remain natural despite online speculation. With its closest Earth approach in December, researchers are preparing for sharper spacecraft images expected to revea...

Planets Could Create Their Own Water While Forming, Expanding Possibilities for Habitable Worlds
Lab experiments show planets can generate water during formation, not just via comets. This suggests habitable conditions may be widespread in the galaxy, expanding possibilities for life-friendly exoplanets.

Scientists May Have Finally Solved the Sun’s Mysteriously Hot Atmosphere Puzzle
Scientists using the Daniel K. Inouye Solar Telescope have detected Alfvén waves in the Sun’s corona, potentially solving the long-standing mystery of its extreme heat and helping refine models of solar and stellar energy transfer.

New Images of Interstellar Object 3I/ATLAS Show a Giant Jet Shooting Toward the Sun
New telescope images show interstellar comet 3I/ATLAS ejecting a giant jet of gas and dust toward the Sun. Scientists say the phenomenon confirms its natural cometary behaviour, offering clues about how such ancient interstellar visitors react to solar heat.

8 Must-Visit Dark Sky Destinations For Astronomy Lovers
Stargazing has captivated humans for centuries, and while city life can make it hard to experience, there are still some incredible spots around the world where the night sky is as breathtaking as it's been for millennia.

New Analysis of 1977 Wow! Signal Reveals Stronger Cosmic Mystery
The famous 1977 “Wow!” signal — a mysterious radio burst detected by Ohio’s Big Ear telescope — has been reanalyzed using modern computing techniques. Researchers digitized old telescope records, finding the signal was about four times stronger than first thought, peaking at 250 Janskys. The recalculations also refined its frequency and s...

Scientists Say Dark Matter Could Turn Failed Stars Into ‘Dark Dwarfs’
Astronomers suggest that brown dwarfs—dim, failed stars—could transform into “dark dwarfs” by capturing dark matter in their cores. When dark matter particles annihilate, they release heat, potentially lighting up these stars. Physicist Jeremy Sakstein and researchers like Jillian Paulin and Rebecca Leane support this idea, which could help...

Dark Dwarfs: New Star-Like Objects May Reveal Nature of Dark Matter
Scientists have proposed a new class of stellar objects called “dark dwarfs,” sub-stellar bodies that may glow faintly from the energy released by annihilating dark matter particles. Found near the galaxy’s core, these objects could hold crucial clues about the elusive nature of dark matter. Powered not by fusion but by WIMP-like particles, d...

Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event
Astronomers have captured the first-ever image of a white dwarf star undergoing a rare double-detonation supernova. Using the Very Large Telescope, the team revealed that such explosions can occur without a star reaching the Chandrasekhar limit. The findings, published in Nature Astronomy, could reshape existing theories about stellar death and imp...

Fast Radio Bursts Reveal Universe’s Missing Matter Hidden in Cosmic Intergalactic Fog
Astronomers have uncovered the universe’s missing baryonic matter using rapid radio bursts. The study, published in Nature Astronomy, shows that most ordinary matter lies between galaxies, hidden in faint intergalactic clouds. This breakthrough highlights FRBs as powerful tools to probe cosmic structures, paving the way for discoveries in large-s...
