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.

Coach attendant returns passenger's bag containing cash, jewellery at New Delhi Railway Station
New Delhi, Apr 10 (PTI): Displaying remarkable integrity, a coach attendant of Sampoorna Kranti Express train found and returned a bag containing cash and jewellery to a passenger, who had mistakenly left it on his seat, the Railway Ministry on Thursday said.
“When the train, which runs between Rajendra Nagar (Bihar) and New Delhi, reached the New Delhi Station, coach attendant Randhir Kumar Singh found a bag full of cash and jewellery,” said Dilip Kumar, Executive Director, Information and Publicity, Railway Board.
Without compromising with his integrity, Singh immediately informed the train ticket examiner (TTE) about the unclaimed bag, he added.
The railway officials said the TTE also acted promptly and searching through the coach chart found out the names and number of passengers, who were sitting near seat number 17/18 in B-4 coach where the bag was found.
“One of the passengers who emerged as the claimant of the bag was Rajan Pathak. Pathak said that he boarded the train from Mirzapur and since there were many family members travelling together, they didn't know who carried which bag,” Kumar said.
“In such a scenario, the bag full of valuables was left at the seat. Pathak returned to the station midway and met the station officials to claim his bag,” he added.
According to station officials, they verified Pathak’s claim to be the owner by asking details of the bag and items that it contained.
After satisfying themselves that Pathak is the actual owner, they handed over the bag to him.
“Rajan Pathak is a priest from Vindhyachal Dham. He appreciated the honesty of the coach attendant and thanked the railways for wonderful service,” Kumar said.
