In the constellation of Sagittarius, three infant planets have been found orbiting a young star 330 light-years from Earth. These are the first planets to be found using the powerful ALMA telescope in ...

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 ...

Many of the most interesting bodies in our Solar System aren’t planets, but the moons that orbit them. They have active volcanoes, hydrocarbon oceans, geysers, and moon-wide oceans buried under icy ...

Astronomers have likely witnessed a planet forming in real time, seen inside a spiral arm of the HD 135344B protoplanetary disc—exactly where theory predicted. The direct light detection is what sets ...

What can rocky planets orbiting in the outer parts of a solar system teach scientists about planetary formation and evolution? This is what a recent study published in Science hopes to address as a ...

This month's NASA/ESA/CSA James Webb Space Telescope Picture of the Month offers us a two-for-one on brand new stars—with some potential planets thrown in as well. This visual highlights Webb's views ...

Free-floating, planetary-mass objects that are just drifting carefree through the galaxy, untethered and starless, appear to be able to generate their own systems of moons, like a planetary system on ...

Astronomers have observed two planets forming in the disc around a young star named WISPIT 2. These observations, and the unique structure of the disc around the star, indicate that the WISPIT 2 ...
