Hubble Reveals How Blue Straggler Stars Stay Young in Ancient Clusters
Astronomers using the Hubble Space Telescope have uncovered new clues to the mystery of blue straggler stars—unusually hot, bright stars found in ancient globular clusters. By studying ultraviolet light from 48 clusters, scientists discovered that blue stragglers are more common in sparse clusters, supporting the idea that they form through binar...

James Webb Watches a Young Star Bake Crystals for Future Planets
Using NASA’s James Webb Space Telescope, astronomers have observed a young star in the Serpens Nebula forging crystalline silicates during powerful outbursts. The findings explain how heat-formed minerals can end up in cold cometary regions and planet-forming disks, shedding light on early stages of planet formation.

Scientists Study 100 Possible Alien Signals as Arecibo’s Historic SETI Search Concludes
Scientists are studying 100 possible alien radio signals identified from Arecibo Observatory data, bringing the 21-year SETI@Home project to a close. Supported by millions of volunteers, the effort found no confirmed alien messages but set new sensitivity standards. Researchers say the findings will guide future searches using more powerful radio t...

A Massive Black Hole Starved Pablo’s Galaxy, Ending Its Star Formation
Astronomers using the James Webb Space Telescope and ALMA have uncovered how a massive black hole shut down star formation in Pablo’s Galaxy. Powerful winds expelled gas at hundreds of kilometres per second, leaving almost no cold fuel behind. The findings suggest many early galaxies did not die explosively, but were slowly starved by their centr...

Indian-Origin Astronomer Wins UK's Royal Astronomical Society Gold Medal
US-based astronomer Professor Shrinivas Kulkarni has been awarded the prestigious Gold Medal by the Royal Astronomical Society (RAS) in London for his "field-defining" discoveries in time-domain astronomy.

Rubin Observatory Discovers Fastest-Spinning Large Asteroid Ever Seen
Astronomers using the Vera C. Rubin Observatory have discovered asteroid 2025 MN45, the fastest-spinning large asteroid ever recorded. About 710 metres wide, the object completes one full rotation every 1.88 minutes—far quicker than any asteroid of similar size. The finding emerged from an early survey that detected nearly 2,000 new asteroids, in...

Hubble Telescope Detects Wake of Betelgeuse’s Hidden Companion Star, Confirming Long-Held Theory
Hubble Telescope observations have revealed a dense gas wake in Betelgeuse’s atmosphere, confirming the presence of a hidden companion star named Siwarha. The discovery explains the red supergiant’s unusual brightness changes and offers new insight into how massive stars evolve and shed material before becoming supernovae.

New Research Suggests the Universe Could Be Lopsided, Raising Cosmology Questions
New research suggests the universe may be asymmetric, challenging the long-accepted Lambda-CDM model and standard cosmology principles.

Astronomers Detect Rare Rogue Planet Drifting Alone 10,000 Light-Years from Earth
Astronomers have confirmed a rare rogue planet, drifting without a star nearly 10,000 light-years away. Using gravitational microlensing, their distance and mass were measured, suggesting that free-floating planets may be abundant across the Milky Way. Upcoming telescopes, including NASA’s Roman Space Telescope and China’s Earth 2.0 mission, ar...

Hubble Observations Turn Exoplanet Into Dust; Reveal Rare Double Asteroid Impact in Nearby System
NASA’s Hubble Space Telescope has revealed that a vanished exoplanet near the star Fomalhaut was never a planet at all. Scientists discovered two rare, violent collisions between asteroid-sized bodies, producing glowing debris clouds that briefly mimicked planets. The findings offer a rare glimpse into how planetary systems evolve and how mislead...

Astronomers Look to the Large Magellanic Cloud to Study How Stars Are Born
The Large Magellanic Cloud is a nearby dwarf galaxy glowing with star birth. Just 160,000 light-years away, it hosts vast nebulae like the Tarantula and historic events such as Supernova 1987A, offering astronomers a rare, close-up laboratory to study how stars form, evolve, and explode.

Wolf Moon Supermoon 2026: Rare January Full Moon Near Perihelion Lights Up the Sky
Skywatchers will be treated to a striking celestial event on January 3, 2026, as the Wolf Moon rises as a supermoon near Earth’s perihelion. Appearing larger and brighter than usual, the full Moon will climb the eastern sky at dusk, accompanied by the brilliant planet Jupiter. This rare alignment—last seen more than a century ago—offers a viv...

NASA Finds Most Distant Calm Galaxy Cluster Ever Seen in Early Universe
Astronomers using NASA’s Chandra X-ray Observatory have discovered SPT-CL J2215-3537, a massive galaxy cluster located 8.4 billion light-years away. Nicknamed the “Champagne Supernova” cluster, it is the most distant relaxed cluster ever observed, showing no signs of recent collisions. Its calm structure and active star formation challenge ex...

Astronomers Decode the Strange Behaviour of a Young Star 1,950 Light-Years Away
Astronomers have found that the young star V1180 Cassiopeiae shows a rare mix of accretion-driven brightening and dust-caused dimming. Based on nearly 25 years of observations, the study explains its long-standing variability and shows how early stellar growth is shaped by tightly linked accretion, extinction, and outflow processes.

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.
