Juno, which has been orbiting Jupiter since 2016, has more and more taken photos of Io’s neighborhood in latest months as its orbit round Jupiter adjustments.
This newest picture was taken simply 1500 kilometers above the moon’s floor. In it, you may see a few of Io’s a whole bunch of towering mountains, a few of which may exceed 10 kilometers in peak, and their lengthy, sharp shadows.
Io is regarded as essentially the most volcanically lively physique within the photo voltaic system, with a whole bunch of lively volcanoes. These volcanoes are typically smaller than the most important mountains, averaging just one to 2 kilometers in peak, and are troublesome to see in photos.
However by evaluating the info with photos from Juno’s earlier 56 lunar passes, astronomers are beginning to perceive how these volcanoes have modified over time and why they’re so lively. You may know.
Juno has additionally been exploring Jupiter’s different moons, together with Europa and Ganymede, amassing knowledge and taking the closest photos. NASA’s Galileo spacecraft In February, Juno will once more fly very shut, about 1,500 kilometers above Io’s floor.
Juno will fly near Io seven extra occasions earlier than leaving orbit for Jupiter on the finish of 2025, however that will not be the tip of studying about Jupiter’s moons. NASA’s Europa Clipper spacecraft, scheduled to launch in October this yr, is designed to fly simply 25 kilometers above the floor of Europa, thought-about one of the vital promising websites for all times on Earth. It will present essential details about the mysterious inland sea. Photo voltaic system. The spacecraft is scheduled to reach at Europa in 2030.
