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 ...

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 ...

The formation of small worlds like Earth previously was thought to occur mostly around stars rich in heavy elements such as iron and silicon. However, new ground-based observations, combined with data ...

Artistic rendering of how small planets can form ‘sandwiched’ in between two larger ones. Scientists have made a new discovery that could explain why small planets often exist between two large ...

You win some, you lose some. Earlier this week, observations made by the Webb Space Telescope provided new data that supports what we thought we understood about planet formation. On Thursday, word ...

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 ...

It's difficult to fathom how much bigger the Sun is than our little planet. Even though it's just an average-sized star, you could squeeze 1.3 million Earths inside it. But planets in other solar ...
