NASA's Juno mission to Jupiter is now in its 10th year. To celebrate, the team has released a new infrared image of Jupiter's largest moon Ganymede.
What was known before was that auroras occurred when ions collided with the Jovian atmosphere, and that there is plasma among its magnetic field lines. Yao found that these ions crash into the atmosphere and release ions in X-ray form when these magnetic field lines trigger waves in the plasma. “The key question was what could periodically force ions to crash into Jupiter’s atmosphere,” Yao tells SYFY WIRE. “Then the question became: how are compressional waves and ion precipitations connected? Electromagnetic ion cyclotron waves are an ideal connection from theoretical plasma physic...
18:02 Expert survivalist rates 10 wilderness survival scenes in movies and TV Juno flew within 645 miles of Ganymede last week - the closest any spacecraft has gotten to the moon in more than two decades. (The last approach was by NASA's Galileo spacecraft in 2000.) Less than a day later, Juno conducted its 34th flyby of Jupiter, snapping photos along the way. Advertisement Citizen scientist Gerald Eichstädt compiled images from both of those journeys into a time-lapse video that shows what it's like to pass by the celestial bodies. The video lasts three minutes and 30 seconds, but in realit...
NASA's Juno spacecraft has sent back the first new images of Ganymede in over 20 years, showing the complex surface of Jupiter's largest moon in great detail.
