Saturn’s largest moon, Titan, might have formed after a collision with a lost moon, according to new research.

NASA’s Hubble Space Telescope got a rare look at the aftermath of two cosmic collisions — and helped scientists solve a decades-old mystery. Many years ago, scientists saw a dense, bright spot near a ...

When you look up at the night sky, planets seem calm and fixed. But a new study shows that nearby planetary systems can be violent and chaotic. Using NASA’s Hubble Space Telescope, astronomers have ...

Astronomers have captured the first-ever direct images of a collision around "Fomalhaut," as published in the journal Science. Fomalhaut is a star system that is just 25 light-years away from Earth.

The Relativistic Heavy Ion Collider (RHIC), the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set of instruments ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

A new climate modeling study presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid. A new climate ...
