When worlds collide…suns act squirrely. Astronomers have witnessed a rare and violent cosmic crash between two planets, and they say the fallout could teach us about the formation of our world. The ...

What does it look like two planets collide? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a pair of resear | Space ...

Astronomers detect a rare planetary collision 11,000 light-years away, offering new clues about how planets and moons form.

They were too big and too far away to exist by the rules. Now, using the James Webb Space Telescope (JWST), an international team of astronomers has finally cracked the chemical code of these distant ...

In the remote outer reaches of planetary systems, far beyond the orbit of known planets, enormous and mysterious worlds silently loop around their stars. Some drift as far as 10,000 times the distance ...

SPHERE’s detailed images of dusty rings around young stars offer a rare glimpse into the hidden machinery of planet formation. These bright arcs and faint clouds reveal where tiny planet-building ...

Planets orbiting two suns are rare. Scientists now understand why. Subtle gravitational forces, amplified by Einstein's relativity, destabilize planetary orbits over eons. This leads to planets being ...

A new study shows that some of the largest and most powerful stars in the universe are producing incredibly tiny particles of carbon dust—material that could one day help form new planets. The ...
