A closer look at the planets around a star called LHS 1903 may just flip our understanding of how planetary systems form.

Stars and planets are inextricably linked. They form together and stars shape the fate of planets. Stars create the dusty protoplanetary disks that give birth to planets of all kinds. And when a star ...

According to these calculations, Earth's total lifespan will be about 9.5 billion years.

An organic molecule called methanimine was found scattered throughout a dense clump of gas and dust 554 light-years away.

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. A red giant star will consume planets close to it, but leave others just right for life. . | ...

This image from a simulation of atmospheric flow shows temperature patterns on one of the newly discovered planets (61Virb), which is hot enough that it glows with its own thermal emission. A movie of ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

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, ...

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 ...

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 ...
