"God Of Chaos" Asteroid To Pass Close To Earth In 2029
Scientists believe that its surface has been altered by long-term exposure to cosmic influences such as solar winds and cosmic rays.

Astronomers Detect Massive 'Cosmic Laser' 8 Billion Light-Years Away
Astronomers using MeerKAT have detected the most distant and powerful "cosmic laser" ever observed, offering new insights into galaxy mergers and the early Universe.

Scientists Trace Rare Cosmic Outburst to a Massive Planetary Collision Around Gaia20ehk
Astronomers have reported evidence of two planets colliding around a distant Sun-like star, Gaia20ehk, located about 11,000 light-years away. The star's light output remained steady until 2016, when it exhibited three minor dimming events; by 2021, the light curve reportedly "went completely bonkers." Follow-up infrared observations revealed a burs...

NASA Captures Rare Neutron Star Collision In Tiny Distant Galaxy
Scientists believe this long stream of gas may have formed when several galaxies collided millions of years ago.

CERN Experiments Confirm Early Universe Behaved Like a Near-Perfect Fluid
Physicists at CERN have directly observed fluid-like behaviour in the quark–gluon plasma that filled the early universe. Experiments at the Large Hadron Collider revealed wake-shaped ripples forming behind fast-moving quarks, similar to bow waves in liquids. These quark wakes confirm that the primordial “soup” of quarks and gluons behaved as ...

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 Spots Starquakes in a Red Giant Orbiting One of the Galaxy’s Quietest Black Holes
A red giant star orbiting a quiet black hole spins faster than expected, while internal vibrations reveal it is younger than its ancient chemistry suggests. These findings hint at a past stellar merger and challenge existing models of star evolution in low-metal environments. Future observations aim to confirm its complex cosmic history.

NASA Captures Asteroids Colliding Around Nearby Star Fomalhaut For The First Time
The team will continue to monitor CS2 using Hubble for the next three years to observe its evolution.

LIGO Detect Possible Second-Generation Black Holes with Extreme Spins
LIGO-Virgo-KAGRA observatories detected two extraordinary black hole collisions in late 2024—GW241011 and GW241110. The first involved a rapidly spinning black hole, while the second revealed one rotating opposite its orbit. These findings fit predictions for second-generation black holes, born from earlier mergers within crowded star clusters. T...

Astronomers Discover Stellar Graveyard Filled With Black Hole and Neutron Star Collisions
Astronomers using LIGO-Virgo-KAGRA detected 128 collisions of black holes and neutron stars, including two rare mixed mergers that double previous records. These findings reveal new details of stellar evolution, refine Hubble constant estimates, and test Einstein’s relativity in extreme conditions. The cosmic “graveyard” offers fresh insight ...
