The deep-sea volcanoes beneath Earth’s oceans may offer vital clues in the search for alien life on Europa, one of Jupiter’s moons. With a $621,000 award from NASA, University of Massachusetts ...

Jupiter, the solar system's largest planet, used to be even bigger, according to a new study. The cloud of gas and dust from which the sun and planets formed dissipated around 4.5 billion years ago.

Jupiter, roughly 562 million miles from Earth today, has nearly 100 moons. But Batygin and his collaborator Fred Adams' research focused on two of the smaller ones, Amalthea and Thebe.

Likewise, its magnetic field — terrifyingly, as it's already 20,000 stronger than the Earth's — would have been a staggering 50 times more powerful.

Jupiter is not only the largest in the solar system, but is so humongous that it's more than twice as massive as the other planets combined. The gas giant is about 11 times wider than Earth alone ...

One of Jupiter’s most recognizable attributes is its sheer size. With a diameter over 88,800 miles, our solar system’s largest planet is 11 times as wide as Earth and twice as massive as all ...

The icy surface of Jupiter 's moon Europa appears to be constantly changing, new data from the James Webb Space Telescope has revealed. This phenomena, the team explained, is heightened in so ...

The Moon passes 5° north of Jupiter at 9 A.M. EDT. Just six percent illuminated by this evening, you can try to spot the young crescent Moon hanging above the gas giant in the western sky after ...

The team's calculations indicate that young Jupiter had a radius nearly twice its current size, with a volume large enough to hold more than 2,000 Earths. As the bloated, magnetic powerhouse ...

While our solar system’s gas giants are far from the sun, the core of a gas giant is likely to be incredibly hot–Jupiter’s is estimated at around 43,000 degrees Fahrenheit.
