Being slight oddities, brown dwarfs occupy a strange but useful niche in astronomy. Unlike exoplanets, which are often difficult to study because they orbit bright stars, most brown dwarfs float ...

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 ...

The Sun makes Earth habitable, governs its climate and drives a variety of natural phenomena through its variable magnetism. Indeed, all planets in and outside the Solar System exist under the ...

A rare image reveals a giant planet clinging to two stars, helping scientists understand how planets survive in chaotic star ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

The James Webb and Very Large telescopes spotted a free-floating planet accreting material at a record rate, displaying behavior similar to how stars form. Scientists aren't clear as to why. When you ...

Our sun is about halfway through its life, which means Earth is as well. After a star exhausts its hydrogen nuclear fuel, its diameter expands more than a hundredfold, engulfing any unlucky planets in ...

Astronomers photographed a baby planet, WISPIT 2b, during its formation process within a dusty ring around its star system.
