NASA's Juno captures closest views of erupting volcanoes on Jupiter's moon Io. Watch!

<p>NASA's Juno mission has made a significant observation of mineral salts and organic compounds on the surface of Ganymede, Jupiter's largest moon. This data was gathered by the Jovian InfraRed Auroral Mapper (JIRAM) spectrometer during a close flyby of Ganymede. The findings are crucial as these observations will now be able to throw light on Ganymede's origin and its deep-ocean composition.</p>

<p>The results of the observation were published in the journal Nature Astronomy on October 30.</p>

<p>Ganymede is even larger than the planet Mercury. This moon, one among more than 80 moons of the planet Jupiter, has attracted scientific interest due to its vast internal ocean hidden beneath an icy crust.</p>

<p>The observation is a breakthrough for scientists as previous observations from NASA's Galileo spacecraft, the Hubble Space Telescope, and the European Southern Observatory's Very Large Telescope had only hinted at the presence of salts and organic compounds. At the time, the spatial resolution of those observations was insufficient to draw definitive conclusions.&nbsp;</p>

<h2><strong>Juno flies over&nbsp;Jupiter's moon,</strong>&nbsp;<strong>Ganymede</strong></h2>

<p>On June 7, 2021, the Juno spacecraft flew over Ganymede at an altitude of 650 miles.</p>

<p>The JIRAM instrument captured infrared images and spectra of the moon's surface. JIRAM, built by the Italian Space Agency, was originally designed to study Jupiter's atmosphere but has also been used to explore the surfaces of Jupiter's Galilean moons - Io, Europa, Ganymede, and Callisto.</p>

<p>The JIRAM data collected during the flyby achieved a remarkable spatial resolution for infrared spectroscopy which exceeded 0.62 miles per pixel.</p>

<p>Using this data, Juno scientists identified and analysed unique spectral features of non-water-ice materials, including hydrated sodium chloride, ammonium chloride, sodium bicarbonate, and possibly aliphatic aldehydes.</p>

NASA's Juno observes mineral salts, organic treasures on Jupiter’s moon Ganymede

<p>You may have seen various photos of Jupiter taken from a distant telescope from Earth. But have you ever seen the mighty planet up close? NASA has released new footage of Jupiter that was taken by the Juno spacecraft that has been hovering over the gas giant since 2016. The US agency has shared an incredible animated sequence created by citizen scientist Andrea Luck using raw JunoCam image data. This clip shows a close shot of the giant planet when the spacecraft flew just 2,050 miles (3,300 kilometres) above the&nbsp;gas giant's cloud tops on April 9.</p>

<p>This was Juno's 41st flyby above the radiation-spewing planet, during which the spacecraft soared at a top speed of 131,000 mph (210,000 km/h) relative to Jupiter, NASA said on May 27.</p>

NASA shares breathtaking close-up clip of Jupiter from Juno spacecraft. Watch!

<p>The National Aeronautics and Space Administration (NASA) has detected&nbsp;FM radio signals from Jupiter's moon Ganymede for the first time.</p>

<p>However, the US space agency clarified that it is a ''natural function'' rather than a sign of extraterrestrial life, that is the existence of aliens.</p>

<p>The signals from Ganymede originated from electrons due to electromagnetic fields. The process causes electrons within to whirl and oscillate much slower than their spin rate.</p>

<p>As a result, all electromagnetic and radio waves get amplified and are picked up by spacecraft hovering in space. These electrons also create auroras in the ultraviolet spectrum.</p>

<p>NASA will extend two of its planetary discovery missions including&nbsp;its Juno which detected the "cyclotron maser instability (CMI)" from&nbsp;Ganymede in the first place.</p>

<p>"Electrons spiralling in Jupiter's magnetic field are thought to be the cause of the radio noise we hear," NASA said in a statement.&nbsp;</p>

<p>Like Earth, Ganymede has a liquid iron core that generates a magnetic field, though Ganymede’s field is embedded within Jupiter’s magnetic field. That sets up an interesting dynamic with telltale visuals – twin bands of glowing aurora around Ganymede’s northern and southern polar regions. As Jupiter rotates, its magnetic field shifts, causing Ganymede’s aurora to rock.</p>

<p>NASA Planetary Science Division Director Jim Green called the finding “an astounding demonstration.” “They developed a new approach to look inside a planetary body with a telescope,” Green said.</p>

<p>Ganymede boasts a lot of water, perhaps 25 times the volume of Earth’s oceans. Its oceans are estimated to be about 500 miles (800 km) deep.</p>

<p>Ganymede is one of five moons in the solar system thought to have oceans hidden below icy surfaces. Two other moons, Europa and Callisto, orbit the big gas planet Jupiter. The moons Titan and Enceladus circle the ringed gas planet Saturn.</p>
