Massive New Volcano Erupts on Jupiter’s Moon Io

Jupiter’s moon Io, the most geologically active spot in the Solar System, has gained a dramatic new volcanic feature that has astonished scientists with its scale and complexity. Known for its frequent volcanic eruptions, Io continues to challenge our understanding of planetary geology with this latest discovery.


NASA’s Juno mission

The latest high-resolution images taken by the JunoCam instrument on NASA’s Juno mission show a recently formed volcano, an impressive addition to Io’s volatile surface, complete with multiple large lava flows and surrounding volcanic deposits covering an area of ​​about 112 by 182 miles.

This discovery not only marks the first close-up study of Io’s surface in more than 25 years, but also adds to the ever-evolving history of this dynamic moon.

The findings were presented this week at the Europlanet Science Congress (EPSC) in Berlin, offering fascinating new insights into Io’s relentless volcanic activity.

Many changes detected in Io

The newly identified volcano is located south of Io’s equator, in a region previously thought to be inactive. Although Io is known for its intense volcanic activity, with hundreds of active volcanoes dotting its surface, images taken by NASA’s Galileo mission in 1997 showed no evidence of volcanic structures in this particular region.

Instead, the region appeared as a smooth, impersonal landscape, devoid of any signs of the violent geological processes that now define it. Michael Ravin is Advanced Projects Manager at Malin Space Science Systems, Inc., the team responsible for developing and operating JunoCam for NASA’s Juno project.

“Our latest JunoCam images show many changes on Io, including this large, complex volcanic edifice that appears to have formed out of thin air since 1997,” Ravin said.

The amazing features of the new volcano Io

The eastern side of the volcano is marked by a widespread red spot, the result of sulfur released by the volcano and subsequently deposited on the surface.

On the west side, two dark lava flows, each about 62 miles long, stretch across the lunar landscape. At the edges of the lava flows, intense heat vaporizes the frozen surface material, creating two distinct gray circles where the lava accumulates.

JunoCam’s unrivaled view of Io

On February 3, 2024, the JunoCam camera captured its best images of this object from a distance of 2,530 kilometers. The low-light image, illuminated only by Jupiter’s glare, provides a unique view of Io’s night side. The new volcanic object is located east of the previously known Kanehekili volcano.

The observations are part of three final flybys of Io in 2023 and 2024, during which JunoCam collected close-up images of nine volcanic plumes. The camera also documented new lava flows and surface changes that highlight ongoing geological transformations on Jupiter’s moon.

JunoCam data is publicly available

Interestingly, the JunoCam data is made publicly available immediately after it reaches Earth. This means that anyone interested in space exploration can immerse themselves in the mission’s findings. The public is encouraged to access the data through the mission’s website and create their own images of Jupiter and its moons, encouraging a collaborative spirit that allows space enthusiasts to participate in the exploration process.

“JunoCam images are created by people from all walks of life, making it possible for anyone to join our science team and share in the excitement of space exploration,” said Scott Bolton, principal investigator of the Juno mission at NASA’s Southwest Research Institute.

Scientific significance of Jupiter’s moon Io

Current observations of Jupiter’s moon Io, particularly its volcanic activity, are providing valuable information about the internal processes of one of the most geologically active bodies in the Solar System. Io’s extreme volcanic behavior, driven by Jupiter’s gravitational tidal forces, is helping scientists better understand how such forces shape the geology of moons and planets.

A new volcano on Io also offers clues about the moon’s evolution and unique volcanic landscape. Continued monitoring of Io will further reveal how its surface is constantly changing under the influence of its fiery interior.
