A four-decade-long study documenting temperatures in Jupiter’s atmosphere using NASA spacecraft has revealed unexpected behavior in the gas giant’s weather over time. NASA says the study is the ...

Jupiter may have formed in a shadow that kept the planet’s birthplace colder than Pluto. The frigid temperature could explain the giant world’s unusual abundance of certain gases, a new study suggests ...

Earth's tropics are hotter than the polar regions for a good reason, so scientists are puzzled that the same pattern doesn't show on Jupiter's moon Io. Earth's tropics are hotter than the polar ...

Hydrogen is the most abundant element in the universe, and a major component of stars such as the Sun, as well as gas-giant planets such as Jupiter and Saturn. In recent years, hydrogen’s behavior at ...

At first glance, giant planets called super-Jupiters might seem like close cousins of Jupiter. Some are even ten times more ...

Since hydrogen is both a highly diffusive and highly reactive element, it is difficult to maintain its stability in high-temperature, high-pressure equipment for use in experimentation, which has ...
