Based on new simulations, scientists believe that giant gas planets across the universe can often collide and merge into even bigger gas plants — behemoths called "super-Jupiters." In the cosmic ...

Scientists uncover a new reason for fewer planets around twin stars. Einstein's theory of general relativity shows that close ...

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 ...

Astronomers have developed the most realistic model to date of planet formation in binary star systems. The researchers, from the University of Cambridge and the Max Planck Institute for ...

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 ...

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 ...

Around the bright star Fomalhaut, astronomers spotted glowing clouds of debris left behind by colossal collisions between large space rocks. One of these clouds was even mistaken for a planet before ...
