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.

Staff Selection Commission implements Aadhaar-based authentication for its recruitment exams
New Delhi (PTI): The Staff Selection Commission (SSC) has decided to implement Aadhaar-based biometric authentication in its all forthcoming examinations in order to verify candidates' identity on a voluntary basis, officials said on Sunday.
They said the new measure will come into force for recruitment tests conducted from next month onwards.
The SSC is one of the largest recruitment agencies of the central government with its main mandate to conduct selections for non-gazetted posts in various central ministries and departments, among others.
"The Commission has decided to implement Aadhar Based Biometric Authentication in its forthcoming examinations.
"Accordingly, candidates will be able to authenticate themselves using Aadhaar at the time of online registration, while filling up online application form for the examinations and while appearing at the test centre to take examinations conducted by the Commission from May 2025 onwards," a recent public notice issued by the recruitment body said.
Such Aadhaar authentication is voluntary and is intended as a measure to promote the ease of engaging with the examination process, the SSC said.
Aadhaar is a 12-digit number issued by the Unique Identification Authority of India (UIDAI) to all eligible citizens on the basis of biometric and demographic data.
The officials said that Aadhaar-based authentication will also help in ensuring that government jobs aspirants do not fake their identity or use other fraudulent means to take recruitment exams conducted by the Commission.
In a notification issued on September 12 last year, the Union Personnel Ministry had said that the SSC is allowed to perform Aadhaar authentication on voluntary basis.
The SSC shall adhere to all relevant provisions of the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits and Services) Act, 2016, "the rules and regulations made thereunder, and directions issued by the ‘Unique Identification Authority of India’," it added.
The Commission conducts seven mandated all India open competitive examinations, including the Combined Graduate Level Examination (CGLE) besides three limited departmental competitive examinations.
The Personnel Ministry had on August 28 last year issued an identical notification, a first for any recruitment agency, to approve Aadhaar-based authentication by the Union Public Service Commission (UPSC).
Lakhs of candidates appear in government jobs recruitment tests conducted across the country by the SSC and UPSC.
The UPSC had last year also decided to use facial recognition and artificial intelligence-based CCTV surveillance systems to prevent cheating and impersonation in its various tests.
The UPSC conducts 14 major exams annually, including the prestigious civil services examination to select officers of the Indian Administrative Service (IAS), Indian Foreign Service (IFS) and Indian Police Service (IPS), besides a number of recruitment tests and interviews every year for induction to Group 'A' and Group 'B' posts of the central government.
