NASA's Hubble Space Telescope observations of Jupiter's icy moon Europa have revealed the presence of persistent water vapor—but, mysteriously, only in one hemisphere.
Astronomers have discovered the very first confirmed planetary system that resembles the expected fate of our solar system, when the Sun reaches the end of its life in about five billion years.
Like the speed of an advancing race car driver, the winds in the outermost "lane" of Jupiter's Great Red Spot are accelerating – a discovery only made possible by NASA's Hubble Space Telescope, which has monitored the planet ...
Like Earth, Jupiter's magnetic field channels electrically charged particles into its atmosphere, resulting in the formation of brilliant aurorae near its poles. However, the brightness and variety of Jupiter's auroral emissions ...
The spacecraft used its infrared instrument during recent flybys of Jupiter's mammoth moon to create this latest map, which comes out a decade after Juno's launch.
New research published in Nature has revealed the solution to Jupiter's 'energy crisis', which has puzzled astronomers for decades.
For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates—that is, turns from solid to gas.
On June 7, 2021, NASA's Juno spacecraft flew closer to Jupiter's ice-encrusted moon Ganymede than any spacecraft in more than two decades. Less than a day later, Juno made its 34th flyby of Jupiter, racing over its roiling ...
The properties of materials under extreme conditions are of key interest to a number of fields, including planetary geophysics, materials science and inertial confinement fusion (ICF). In geophysics, the equation of state ...
The Jupiter Icy Moons Explorer has moved into the "Large Space Simulator" at ESA's test center, ready for grueling environmental tests at a range of temperatures.
