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

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 ...

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

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. . | ...

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

A distant star dimmed by 97% for nearly 200 days. Astronomers say giant rings around a brown dwarf or super-Jupiter may explain it.

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

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

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an ...

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 ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...
