Infrared tech aboard the area company’s Juno probe mapped two such eruptions in February, returning invaluable knowledge on the mysterious happenings beneath Io’s floor. Researchers shared their insights on the matter in a paper revealed final week.Florida Household Takes NASA to Court docket Over Dwelling Broken by Area TrashFrom round 2,400 miles away, the probe’s Jovian Infrared Auroral Mapper (JIRAM) instrument “revealed that the entire floor of Io is roofed by lava lakes contained in caldera-like options,” defined Alessandro Mura, a Juno co-investigator from Rome’s Nationwide Institute for Astrophysics. On Earth, a caldera is a crater fashioned by a collapsing volcano. Io is a couple of quarter the dimensions of Earth by diameter, and only a bit larger than Earth’s moon.“Within the area of Io’s floor through which now we have essentially the most full knowledge, we estimate about 3% of it’s coated by one in every of these molten lava lakes,” stated Mura. Juno’s JIRAM software got here by way of Italy’s area company, Agenzia Spaziale Italiana.In response to Mura, lead writer of the Io paper, the probe’s flybys expose the most typical sort of volcanism on Jupiter’s hottest moon — “monumental lakes of lava the place magma goes up and down.” He added, “The lava crust is compelled to interrupt towards the partitions of the lake, forming the standard lava ring seen in Hawaiian lava lakes. The partitions are probably lots of of meters excessive, which explains why magma is usually not noticed spilling out.”Researchers are nonetheless poring over the info collected by Juno’s Io flybys, which occurred in February 2024 and December 2023.
