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 ...

Cosmic Visitor: 4.56-Billion-Year-Old Meteorite Strikes into Georgia Home
On June 26, 2025, a dazzling daytime fireball streaked over Georgia, captured by satellites and witnessed across multiple states. A surviving fragment smashed through the roof of a McDonough home, denting the wooden floor 14 feet below. Scientists at the University of Georgia analyzed about 23 grams of this ancient rock, determining it to be a 4.56...

James Webb Telescope Spots Rare ‘Cosmic Owl’ Formed by Colliding Galaxies
NASA’s James Webb Space Telescope has unveiled the “Cosmic Owl,” a jaw-dropping image of two colliding ring galaxies forming a structure that resembles an owl’s face. This double-ring formation is extraordinarily rare, and the event is shedding light on galaxy evolution, black hole dynamics, and rapid star formation. Led by Ph.D. student Mi...

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...
