Ancient Star in Pictor II Reveals Secrets of Early Universe
Astronomers have discovered one of the oldest known stars, PicII-503, in the Pictor II dwarf galaxy. With extremely low iron content, the star offers rare insight into the second generation of stars and the early chemical evolution of the universe.

All 5 DNA And RNA Building Blocks Found In Asteroid Ryugu Samples. Here's What It Means
The study's lead author said that the presence of nucleobases "does not mean that life existed on Ryugu".

Scientists Solve Mystery Of Puzzling Radio Pulses From Space
Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, might finally add some clarity.

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.
