On March 9, 1979, Linda Morabito discovered a volcanic plume on Io, a moon of Jupiter, in one of the photos from Voyager 1. She wrote, “I could feel tears begin to roll down my face at the sight ...

Lava lakes on Io's surface had previously been found in a few locations, such as the 127-mile-long lake Loki Patera. This study reveals that these lakes are extremely common on the moon, and the ...

Even so, planetary scientists were surprised when one of Io’s volcanoes pulled off the record-breaking eruption. The event, which took place on Feb. 22, 2001, was twice as powerful as any other ...

The new one is located just south of Io’s equator and the Juno images show fresh lava flows and volcanic deposits covering an area of 32,400 square kilometers (12,510 square miles).

They’ve Been Watching Its Explosions. Researchers have released a five-year record of volcanic activity on Io, a moon of Jupiter, hoping others will find more patterns.

The volcanoes on the poles are smaller than those in the lower latitudes, the researchers found, but it's clear there's lively volcanic activity all over Io. Scientists have found 266 active hot ...

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 ...

NASA orbiter spots most active volcano yet on Io The third and latest flyby, which took place on Dec. 27, 2024, brought the Juno spacecraft within about 46,200 miles of the moon.

The mystery of Io’s misplaced volcanoes called for a different explanation–one that had to do with the interaction between heat produced by fluid flow and heat from solid-body tides.

Io is similar in size to Earth’s moon, but it’s a much more active place. Its surface is dotted with incredibly active volcanoes, and astronomers studying Io might have just spotted yet ...
