Scientists have found a volcano near the south pole of Jupiter’s moon Io, utilizing knowledge collected by NASA’s Juno spacecraft.
The infrared knowledge had been collected in December final yr, when Juno was about 470,000 kilometres away from the moon, utilizing its Jovian InfraRed Auroral Mapper (JIRAM) instrument
“The new Io hotspot JIRAM picked up is about 200 miles (300 kilometers) from the nearest previously mapped hotspot,” stated Alessandro Mura, from the National Institute for Astrophysics in Italy.
“We are not ruling out movement or modification of a previously discovered hot spot, but it is difficult to imagine one could travel such a distance and still be considered the same feature,” stated Mura.
The crew will proceed to judge knowledge collected on the December 16 flyby, in addition to JIRAM knowledge that might be collected throughout future flybys of Io.
Past NASA missions of exploration which have visited the Jovian system (Voyagers 1 and a pair of, Galileo, Cassini and New Horizons), together with floor-primarily based observations, have situated over 150 lively volcanoes on Io to date.
Scientists estimate that about one other 250 or so are ready to be found.
Juno has logged practically 235 million kilometers since coming into Jupiter’s orbit on July four, 2016. Juno’s 13th science cross might be on July 16.
Juno launched on August 5, 2011, from the US. During its mission of exploration, Juno soars low over the planet’s cloud tops – as shut as about three,400 kilometres.
During these flybys, Juno is probing beneath the obscuring cloud cowl of Jupiter and learning its auroras to study extra concerning the planet’s origins, construction, environment and magnetosphere.PTI
