Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter ...

Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their ...

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 ...

Earth’s habitability may trace back to a precise chemical balance during its formation, one that kept life-critical elements from disappearing into the core or drifting into space.

What specific processes are responsible for planetary formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

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

How do water and hydrogen interact in planetary evolution? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of researchers investigated the ...
