"These two planets have densities comparable to a nice blob of shaving foam fresh from the can." ...

Recent research suggests that giant planets may form around supermassive black holes, challenging traditional views that ...

Theoretical astrophysicists have calculated that the dense dust rings swirling around supermassive black holes could spawn ...

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 ...

Astronomers using ALMA have discovered that planet-forming discs are not flat and serene but subtly warped, reshaping our understanding of how planets form. These slight tilts, similar to those seen ...

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 ...

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 ...

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 ...

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 ...

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 ...

Venus, Jupiter and Mercury are due to form a planet parade in June visible across the US. What to know, including the date and time and where to look.
