On Jupiter there's an aurora that glows continually. Now, new observations reveal that this display sometimes flares up because of a process that has absolutely nothing to do with the sun.
Long before Mercury, Venus and Earth formed, our solar system may have harbored other planets. In fact, scientists believe that it may have possessed super-Earths, which are planets larger than Earth but smaller than Neptune.
After watching aurorae glowing above Jupiter's moon, Ganymede, scientists believe that the world may possess an underground ocean.
The Hubble Space Telescope has captured some images of a rare occurrence. It's caught three of Jupiter's largest moons passing in front of the gas planet's banded face.
A swarm of tiny probes may have a mission--and that mission is the giant planet of Jupiter. Microprobes, which each have a different sensor, could be fired into the clouds of Jupiter and grab data as they fall before burning up in the gas giant planet's atmosphere.
What causes Jupiter's Great Red Spot to actually be red?
NASA's Hubble Space Telescope has helped a team of scientists to make the most detailed global map yet of the glow of a turbulent planet outside our solar system.
Astronomers have spotted two new Jupiter-sized planets orbiting a stars in a binary-star system. The findings reveal an unusual case for the extra-solar planets, most of which orbit stars that are alone.
It turns out that "hot Jupiters" have more of an effect on their host stars than scientists once though. Astronomers have found that these large, gaseous exoplanets can make their stars wobble when they pass through their own solar systems.
Three massive volcanic eruptions on Jupiter's moon, Io, have made astronomers think twice about how often these outbursts occur.
Jupiter's icy moon, Ganymede, and our own planet Earth may have more in common than you might have thought at first.
Astronomers have learned a bit more about Jupiter's moons using the Subaru Telescope and the Hubble Space Telescope. They've found that these satellites remain slightly bright, even when in the shadow of the massive Jupiter.
