Recent simulations and research have unveiled a fascinating new insight into the history of the solar system’s terrestrial planets. For years, scientists speculated about how the rocky planets—Earth, ...

An artist's impression of the planetary system surrounding LHS 1903, a small red dwarf star cooler and dimmer than our Sun. (European Space Agency) (CN) — For decades, astronomers thought they had ...

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 ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow ...

NEW YORK (CNN) — An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the ...

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 ...

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 an extrasolar planet with the largest core of any known planet. The discovery is especially exciting to planet formation theorists, because it provides extremely strong ...

One way gas giants form is through core accretion, where solid cores gradually grow in a disk by pulling in rocky and icy pebbles until they become massive enough to attract the gas that surrounds ...
