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 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 ...

Most of the planets we’ve identified are in orbit around stars and formed from the disks of gas and dust that surrounded the ...

Searches for exomoons should target smaller rocky exoplanets, according to simulations of how Earth's moon formed. When you purchase through links on our site, we may earn an affiliate commission.

Science teaches us that stars are much larger than planets, but what about large planets that orbit small stars? This is what a recent study published in Nature Astronomy hopes to address as a team of ...

Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet ...

How did a planet this big form around a star this small? An international team of astronomers, including researchers from the University of Liège and collaborators in UK, Chile, the USA, and Europe, ...

Many of the stars in the Milky Way galaxy are small, dim red dwarfs—stars much smaller than the sun in both size and mass. TOI-6894, located far away from Earth, is one of them. Astronomers previously ...

Young stars much less massive than the sun can unleash a torrent of X-ray radiation that can significantly shorten the lifetime of planet-forming disks surrounding these stars. This result comes from ...

"There really is something very different about how these giant planets form versus how small planets like Earth form." When you purchase through links on our site, we may earn an affiliate commission ...
