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

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

Far beyond our solar system, in the distant Pegasus constellation, lies a star system that is reshaping our understanding of planetary formation. HR 8799, located 129 light-years away, is home to a ...

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 ...

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

Rogue planets may have more in common with stars like our sun than astronomers realized. About 620 light-years from Earth, a gigantic rogue proto-planet is currently devouring 6.6 billion tons of dust ...

Astronomers have found evidence of a process that supports an alternative, more rapid approach to planetary formation, more top down than bottom up. By Katrina Miller When it comes to making a planet, ...

The formation of planets is a fascinating process. They usually originate in a disc of dust and gas surrounding stars. When particles come together, they form a clump, and through a process called ...

If you’re looking to visit a gas giant planet in another solar system — or if you’re simply a science fiction writer who needs such a world for your story — you’d better steer clear of little red ...
