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 ...

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, ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

I recall as a child lying on the grass at night, gazing up at the stars, and wondering if any of those distant suns had planets orbiting nearby. I was not the first to do so, of course. The question ...

Illustration of the planetary system of L 98-59: five small exoplanets orbit closely around this red dwarf star, located 35 light-years away. In the foreground is the habitable-zone super-Earth L ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that ...

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.

Astronomers have identified a frozen, Earth-sized world circling a nearby sunlike star, a find that sharpens the search for planets that resemble our own while underscoring how rare truly temperate ...
