Jupiter

High-resolution images taken by the Hubble Space Telescope of Jupiter’s Great Red Spot have revealed that it’s not as stable as we thought. Instead, the Spot is squeezing in and out, with NASA describing it as “jiggling like a bowl of gelatin.”

The largest moon in our solar system may have been knocked off its axis and cracked like an egg four billion years ago by an asteroid bigger than the one that wiped out the dinosaurs on Earth at the end of the Cretaceous age.

Data from NASA's Juno Jupiter orbiter suggests that the Jovian moon Europa produces about 26 lb/s (12 kg/s) of oxygen or almost 100 times less than previously estimated. This changes the probability of life being found in the moon's subterranean ocean.

NASA has released a high-resolution image taken by the Juno deep space probe during its close encounter with Jupiter's moon Io on December 30, 2023. The image of the volcanic satellite not only shows remarkable details, but an unusual kind of lighting.

On December 30, 2023, NASA's Juno deep space probe made the closest flyby of Jupiter's moon Io in over two decades. The robotic spacecraft passed within 930 miles (1,500 km) of the volcanic satellite, returning closeup images of the south pole.

Hiding within new images of a nebula captured by the James Webb Space Telescope, astronomers have made a puzzling discovery – dozens of Jupiter-sized objects that defy explanation.

Although Saturn's moon Enceladus and Jupiter's moon Europa both have ice-covered surfaces, oceans may exist beneath that ice. The TRIPLE-nanoAUV 2 project is aimed at getting an uncrewed submersible into those oceans, to search for life.

NASA's Juno deep space probe has made its closest flyby yet of Jupiter's volatile moon Io. During its 51st orbit of the giant planet, the solar-powered robotic spacecraft came within 22,600 miles (35,500 km) of Io's volcanic surface.

Saturn has overtaken Jupiter as the planet with the most known moons in the solar system. Astronomers have announced a bumper crop of 62 new moons orbiting the ringed planet, pushing its total to well over 100.

ESA's Juice Jupiter mission is back on track after Mission Control in Darmstadt, Germany managed to shake loose and deploy the stuck ice-penetrating Radar for Icy Moons Exploration (RIME) antenna that was stuck due to a tiny pin.

ESA's Juice probe has run into trouble as one of its instruments failed to deploy, perhaps due to a tiny pin. The Radar for Icy Moons Exploration (RIME) antenna has only extended a third of its length and failed to release from its mounting bracket.

ESA's Juice deep-space probe is on its way to Jupiter and has sent back its first selfies. Captured by Juice monitoring camera 1 (JMC1) located on the front of the spacecraft, the new images show the Earth and Juice's deployed solar array.
