Scientists have used data from NASA's retired planet-hunting space telescope 'Kepler' to discover that small and large worlds have very different upbringings. The team found that larger planets on non ...

UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Imagine you’re a farmer searching for eggs in the chicken coop – but instead of a chicken egg, you find an ostrich egg, much larger than anything a chicken could lay. The smaller star, called an M ...

Scientists using a NASA space telescope have discovered a tantalizing world. It's about the size of Earth, sits remarkably close to our solar system, and could be comfortable for life as we know it.

The fate of Neptune-like worlds that migrate close to their star is to be whittled away by stellar radiation. When you purchase through links on our site, we may earn an affiliate commission. Here’s ...

In the Star Wars movies fictional planets are covered with forests, oceans, deserts, and volcanoes. But new models from a team of MIT, NASA, and Carnegie scientists begin to describe an even wider ...

Transitional disks represent a short stage of the evolution of circumstellar material. Studies of dust grains in these objects can provide pivotal information on the mechanisms of planet formation.

A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a UC Riverside experiment. UCR astrophysicist ...

"There really is something very different about how these giant planets form versus how small planets like Earth form." Scientists have used data from NASA's retired planet-hunting space telescope ...
