China and NASA Coordinate to Avoid Satellite Collision for the First Time
China’s CNSA made history by alerting NASA to a possible satellite collision—marking the first instance of Beijing warning Washington in orbit. With Earth’s orbits growing crowded from megaconstellations like Starlink and Guowang, the event signals a new phase of cooperation in global space traffic control and shared responsibility for orbita...

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...

Rising Satellite Traffic in Low Earth Orbit Sparks Collision Risk Concerns
A new study in Acta Astronautica warns that Low Earth Orbit is becoming dangerously congested. Since 2019, the number of satellites performing more than ten collision-avoidance maneuvers per month has risen sevenfold. With nearly 25,000 tracked objects and more launches planned, scientists fear a chain-reaction risk and call for stronger global coo...

Asteroid Belt Is Slowly Fading, Study Finds
A recent study shows the asteroid belt is slowly losing material due to gravitational forces and collisions, with implications for Earth's past and future impact risks.

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 ...

Mars' Interior Holds Evidence Of Violent Early History, NASA Scientists Confirm
NASA scientists have discovered massive fragments of ancient planetary collisions buried deep in Mars' mantle, using seismic data from the InSight lander.

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...

JWST Finds Black Hole Between Galaxy Cores, Hinting at Rare Direct Collapse Birth
Using JWST, astronomers discovered a black hole between two galaxy cores in the Infinity Galaxy—possibly the first direct evidence of a black hole formed by gas collapse, not stellar death. This rare “heavy seed” black hole challenges standard models and could help explain how supermassive black holes appeared so soon after the Big Bang.

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...

Mars Dust Devils May Spark Lightning, Might Pose Risks to Rovers: Study
A new computer-modeling study reveals that dust devils on Mars—swirling columns of dust and air—may become electrically charged enough to spark lightning-like discharges. Led by researcher Varun Sheel, the study simulates how dry Martian conditions and frictional collisions between dust grains can generate strong electric fields inside these vo...

Iran’s Folded Rocks Reveal Ancient Tectonic Power at Asia-Europe Boundary
Iran’s Zagros Mountains showcase tightly folded rock layers caused by the slow-motion collision of the Arabian and Eurasian plates. Visible from space, these dramatic geological structures reveal the raw power of continental tectonics and provide scientists with valuable insights into mountain formation, seismic activity, and Earth’s ongoing st...

NASA Shares Planetary Defense Strategy to Protect Earth From Potential Asteroid Strikes
NASA and international scientists closely tracked asteroid 2024 YR4, which initially showed a rare 3 percent collision probability with Earth. Although the threat has now diminished, the incident highlights the importance of asteroid surveillance, open data, and upcoming space missions like NEO Surveyor.
