We know that our Solar System is not the blueprint for all planetary systems out there. There are gas giant planets orbiting ...

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

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 ...

Relatedly, astronomers may have just pushed the upper size limit of what counts as a planet.

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't have hard surfaces. Jupiter and Saturn are the gas giants in our solar ...

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, ...

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

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 ...

Hot Jupiters were once cosmic oddities, but unraveling how they moved so close to their stars has remained a stubborn mystery. Scientists have long debated whether these giants were violently flung ...

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 ...
