NASA's Juno data points to new volcano on Jupiter moon Io
Washington, July 14 : Using data collected by NASA's Juno spacecraft, scientists have got clues to a previously undiscovered volcano on the Jupiter moon Io.
With its Jovian InfraRed Auroral Mapper (JIRAM) instrument, the Juno spacecraft found a new heat source close to the south pole of Io, NASA said on Saturday.
"The new Io hotspot JIRAM picked up is about 300 kilometres from the nearest previously mapped hotspot," Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome, Italy, said in a statement.
"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," Mura added.
The infrared data were collected on December 16, 2017, when Juno was about 470,000 kilometers away from the moon.
The Juno team will continue to evaluate data collected on the December 16 flyby, as well as JIRAM data that will be collected during future (and even closer) flybys of Io, NASA said.
Past NASA missions of exploration that have visited the Jovian system (Voyagers 1 and 2, Galileo, Cassini and New Horizons), along with ground-based observations, have located over 150 active volcanoes on Io so far.
Scientists estimate that about another 250 or so are waiting to be discovered.
Juno has logged nearly 235 million kilometres since entering Jupiter's orbit on July 4, 2016.
Juno's 13th science pass will be on July 16, the US space agency said.

Jhansi: Dalit youngster assaulted, stripped after picking him up on pretext of giving cigarettes
Jhansi: A Dalit youngster was assaulted and humiliated by a group of men in a village under Premnagar police station limits on November 22, after being taken away on the pretext of being offered a cigarette. The incident came to wider attention after a video of the assault surfaced on Thursday.
According to the complaint, the youngster was standing near Goswami Restaurant in Rajgarh when Nishant Saxena, Sukrit and Kanishk approached him and asked him to accompany them. He was allegedly taken on a scooter to Saxena’s house, where two others Bhanu Pal and Ravindra were present. The group is accused of beating him with slippers, fists, kicks and sticks, abusing him with caste slurs, recording the assault on video and threatening him with a firearm, The Observer Post reported.
The video shows the youth being repeatedly slapped and kicked, forced to apologise, and made to touch one of the assailants’ feet. It also shows a man, identified as Saxena, pointing a firearm at him and ordering him to undress. The youngster is heard pleading with folded hands, saying he does not want to be taken to the police station.
CO Sadar Ramveer Singh said a case has been registered under sections of the Bharatiya Nyaya Sanhita and the SC/ST (Prevention of Atrocities) Act. He confirmed that three accused Sukrit, Anand Nayak and Kanishk Ahirwar have been arrested, while the main accused, Nishant Saxena, remains absconding.
