00:04 NASA's Juno spacecraft is at it again, delivering some of the most high-resolution and amazing photos of Jupiter's wildest moon.
00:11 These are close-up images of Io, our solar system's most volcanic hotspot.
00:16 And if you look more closely, you can actually see volcanic eruptions spewing material out into space.
00:21 The images were captured just 930 miles above the surface of the moon,
00:25 with experts identifying dozens of volcanic eruptions via infrared imaging.
00:30 So why is Io so volcanically active? Well, it all has to do with gravity.
00:34 Io is sandwiched between Jupiter and two other moons, Europa and Ganymede.
00:38 According to NASA, that effectively causes a gravitational tug-of-war between the moons and the planet, creating a frictitious situation.
00:45 The result is a constantly deforming moon with more than 400 active volcanoes.
00:50 In fact, Insider reports that Io's largest active volcano is around twice the size of Earth's,
00:55 despite the moon being only around a quarter of our planet's diameter.
00:59 Juno is expected to continue its passes of Jupiter and its rings and moons until September 2025.
