NASA's Juno spacecraft has discovered a giant volcanic hot spot on the surface of Jupiter's hellish moon Io. The eruptions in this area are chucking out six times the energy being produced by all Earth's power stations, researchers say.

On a recent flyby, the Juno spacecraft spotted intense volcanic activity on Io, one of Jupiter's moons. It was more extreme than any volcanism ever seen on Io. The post Juno spots most extreme volcanic activity on Io to date first appeared on EarthSky.

NASA's Juno spacecraft has found salts and organics on Jupiter's largest moon, Ganymede. They suggest that watery brines came up to the surface from deep below. The post Jupiter's moon Ganymede is coated in salts and organics first appeared on EarthSky.

NASA's Juno spacecraft has found that Jupiter's winds whip around the planet's turbulent atmosphere cylindrically.

The violent nature of Jupiter's atmosphere has long been a source of fascination for scientists.

The Juice spacecraft will zoom in on the moon Ganymede, which might have a habitable ocean deep underground.

NASA's Juno mission is set to photograph more views from this moon on Dec. 15.

These images of Jupiter's icy moon Europa were taken by the JunoCam instrument aboard NASA's Juno spacecraft during a close approach on September 29, 2022.

This black-and-white image of Jupiter's icy moon Europa was taken by the Stellar Reference Unit (SRU) instrument on board NASA's Juno orbiter during a close flyby on September 29, 2022.

A NASA probe will swoop to around 350 kilometres above Europa's surface on 29 September, returning detailed images and data on its magnetic fields and icy crust

Even by the standards of Io, the most volcanic celestial body in the solar system, recent events observed on the Jovian moon are extreme.

A new volcano has been spotted on Jupiter's moon Io, the most geologically active place in the solar system. Analysis of the first close-up images of Io in over 25 years, captured by the JunoCam instrument on NASA's Juno mission, reveal the emergence of a fresh volcano with multiple lava flows and volcanic deposits covering an area about 180 kilometers by 180 kilometers. The findings were presented at the…

This week, an analysis of ancient DNA sheds light on a bygone empire, Voyager 1 is back in touch with NASA, what to do now that the cicadas are here, and...

Imagery from the solar-powered spacecraft provides close-ups of intriguing features on the hellish Jovian moon.

On February 3, 2024, NASA's Juno spacecraft made a second close flyby of Io, the fifth of Jupiter's moons and the third largest.

The NASA spacecraft Juno captured the images during a flyby on Saturday. Scientists are hoping to learn more about Io, the most volcanic world in the solar system.

The spacecraft will make its nearest approach to the Jupiter's volcanic moon this week.

NASA's Juno spacecraft is preparing for a close flyby of Jupiter's moon Io, which scientists hope will lend insight into the structure of the volcanically active moon.

NASA's Juno spacecraft detected organic compounds and mineral salts on the surface of Jupiter's largest moon, Ganymede, hinting at a salty subsurface ocean.
