Astronomers have finally figured out how the most common types of planets in our galaxy are formed—by watching a set of baby planets grow up in real time. These worlds, found in a young star system ...

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

Infant planets are ravenous little blighters that quickly devour what remains of the star-circling gas and dust clouds in which they form. The gas in these protoplanetary disks disappears rapidly, ...

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

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

A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST’s powerful vision, astronomers detected sulfur in their atmospheres — a chemical clue that they formed ...

Researchers have discovered more than 6,000 exoplanets in our Milky Way. Of these, the sub-Neptune class, which are smaller than Neptune and more massive than Earth, are the most common. These planets ...
