WASHINGTON (Reuters) -Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star. The discovery defies current understanding of how ...

Astronomers have discovered a strange giant planet orbiting a tiny star - and nobody knows how it got there. The star is a distant red dwarf known as TOI-6894 which is just a fifth the mass of our own ...

A recent astronomical discovery has shaken long-held beliefs about how planets form. For decades, scientists thought that stars much smaller than our Sun couldn't form giant planets. That theory just ...

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, ...

Astronomers announced Wednesday they have discovered a massive planet orbiting a tiny star, a bizarre pairing that has stumped scientists. Most of the stars across the Milky Way are small red dwarfs ...

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 ...

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 ...

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 ...
