Astronomers using the James Webb Space Telescope (JWST) may have identified the smallest star in the known universe — or at least, the smallest known object that began forming like a star, before ...

The star, TMTS J0526B, is a hot subdwarf that is only seven times the size of Earth, making it smaller than Saturn. This small stellar body, located approximately 2,760 light years away from Earth, ...

Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a ...

The host star, TOI-6894, is a red dwarf with only 20% the mass of the Sun, typical of the most common stars in our galaxy. Until now, such low-mass stars were not thought capable of forming or ...

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 ...

NASA's Webb telescope spotted what is likely the smallest brown dwarf ever observed. Brown dwarfs are some of the most unusual objects in the universe. They aren't a star or a planet. In theory, such ...

It's impossible to tell for sure how many stars there are in the Universe for the simplest reason that it's impossible to see them all, let alone count them. Some estimates, based on, well, more or ...

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 ...
