Scientists have discovered a rare six-planet system, HD 110067, where all planets orbit their star in perfect mathematical ...

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 ...

Large and small planets are born from very different circumstances, according to data from NASA's now-retired space telescope Kepler. It found that larger planets with non-circular orbits are more ...

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 ...

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 universe can be a pretty violent place. Astronomers have theorized that dying stars might even consume entire planets as they expand near the end of their lives but have never watched it happen, ...

An asteroid named 2025 PN7 has been in quasi-orbit of Earth for approximately 60 years. It's expected to stay there for ...

NASA's forthcoming Nancy Grace Roman Telescope will hunt for "cosmic orphans," starless planets that might even outnumber their orbiting counterparts in our galaxy. When you purchase through links on ...

Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole’s powerful gravity rips the star apart, sending a long streamer of gas ...

Scientists thought they saw a distant star swallow a planet for the first time ever. But new observations from the James Webb Space Telescope suggest something very different, but equally rare, may ...
