New simulations suggest Jupiter holds far more water than once thought, reshaping ideas about how the largest planet formed.

For decades, planet formation existed mostly in theory and simulations. Now, astronomers have captured direct evidence ...

In the swirling clouds of gas and dust that surround newborn stars, planets begin to form. These planet-forming disks are rich with clues about how worlds like Earth come to be. Until now, scientists ...

Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That's been a source ...

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 ...

The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...

Visualisation of the warped disc around the young star MWC 758, with warping exaggerated by a factor four to make it visible. Both panels show properties of the disc inferred from CO emission. On the ...

Astronomers have discovered a giant Saturn-sized planet orbiting TOI-6894, the smallest star ever known to host such a world. The finding overturns long-held theories suggesting that tiny, low-mass ...
