NASA's Juno locates undiscovered Volcano on Jupiter's Io moon

At that time, the Juno spacecraft was about 290,000 miles away from Io.

Images captured by Juno's Jovian InfraRed Auroral Mapper (JIRAM) instrument in the infrared reveal a hot spot detected December 16, 2017, when the probe came within 290,000 miles (470,000 kilometers) of the innermost Galilean moon.

Alessandro Muller, a joint researcher at Juno National Institute of Astrophysics in Rome, said in a statement: "The new Io hotspot JIRAM is about 300 kilometers from the hot spot on the nearest map". Juno's 13th science pass will be on July 16th.

The device Juno, which studied Jupiter using the instrument Jovian InfraRed Auroral Mapper, found a new heat source near the South pole of the moon IO that could indicate a previously undiscovered volcano on a small moon of Jupiter.

This annotated image highlights the location of the new heat source close to the south pole of Io.

The Juno team will continue to evaluate data collected during the flyby on December 16, and JIRAM data that will be collected during future approach to IO.

Io is the most volcanically active world in the Solar System and harbors hundreds of erupting volcanoes, some of which blast lava as high as 250 miles.

Juno has traveled nearly 146 million miles (235 million kilometers) since entering orbit around Jupiter on July 4, 2016.

NASA's Juno spacecraft was launched on August 5, 2011, from Florida's Cape Canaveral. During its mission of exploration, Juno soars low over the planet's cloud tops - as close as about 2,100 miles (3,400 kilometers). NASA agreed to Fund the project Juno mission until 2022 fiscal year and thereby extend the scientific research for another 41 months.
