"We do not exclude the movement or modification of the previously identified hot spot", added Alessandro Mura, the researcher team Juno from the National Institute of astrophysics in Rome.
This small Galilean moon - which, according to data from NASA's Juno mission, leaves footprints in Jupiter's aurorae whenever it comes close to the gas giant, the Inquisitr reported last week - is extremely temperamental. It detected InfraRed data through the InfraRed Auroral Mapper instrument on December 16, 2017.

Juno spacecraft made a close flyby to Io on December 16, 2017, and it was during this close approach that NASA initially came to know about the mysterious heat source which was never documented before.
Washington Using data collected by NASA's Juno spacecraft, scientists have got clues to a previously undiscovered volcano on the Jupiter moon Io. It has a diameter of 2,264 miles (3,640 kilometers) and is the Solar Systems' most volcanically active world. The space agency has mapped more than 150 active volcanoes on the surface of Io, and many of them are continuously erupting lava fountains up to 250 miles high.
Recall that the Juno probe reached Jupiter in July 2016. At the time, Juno was about 44,300 miles (71,400 kilometers) from the planet's cloud tops, above a southern latitude of 71 degrees.
