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 ...
The planets orbit a star around 133 light-years away from Earth.
Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter ...
Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...
The discovery provides new insights into the question, 'how large can a planet be?' An illustration of the HR 8799 system with three of its gas ...
Recent research suggests that Saturn's bright rings and its largest moon, Titan, may have both originated in collisions among ...
Between 7 satellite fly-bys and 2 dedicated missions, you'd think our knowledge about Jupiter would be pretty solid, but we're still learning more.
New data from NASA's Juno orbiter reveals Jupiter is slightly smaller and more 'squashed' than scientists previously thought.
Jupiter, without a doubt, is the biggest planet in our solar system. But it turns out that it is not quite as large – by ...
New observations from NASA's James Webb Space Telescope (JWST) suggest that even extremely massive gas giants — once thought ...
If a gas giant planet is big enough to ignite deuterium fusion, it becomes a brown dwarf instead of a planet. But this definition is incomplete and does not tell us how gas giants form or what ...
