The Juno probe from NASA takes a look at the volcanic world of Jupiter’s moon Io.

The Juno mission, which is run by the space agency, has been getting closer and closer to Jupiter’s moon Io, which is known for its volcanoes and lava and is geologically active.

Early in March, Juno was about 32,044 miles away from Io. On May 16, it went by the moon again, but this time it was only 22,060 miles away, so it could get better pictures.

In the following year, the gap between Juno and Io will continue to get closer and closer, until it is only 930 miles (1,500 km) away.

When you compare this to the Hubble telescope, which orbits about 332 miles above Earth, you can see how close this is.

Scott Bolton, who is in charge of the Juno mission, told Mashable in March, “We’re getting closer and closer.”

During Juno’s 51st trip around Jupiter, these pictures were taken. Even though Juno is not heading straight for Io, it is doing close flybys of the nearby gas giant as it continues its path around it.

Planetary experts can learn a lot from the pictures that were taken.

In a release, Bolton said, “Io is the most volcanic celestial body we know of in our solar system.”

“By looking at it from different angles over time, we can see how the volcanoes change, like how often they erupt, how bright and hot they are, if they are part of a group or stand alone, and if the shape of the lava flow changes.”

The Juno probe takes a look at Jupiter’s volcanic moon Io.
Io’s volcanic scenery is caused by the fact that it is stuck in the middle of a battle between the huge planet Jupiter and two other important moons, Ganymede and Europa, which may have a large ocean.

Io, a moon a little bigger than ours, gets very hot inside because of this ongoing tug-of-war between its gravity and that of the sun. Huge amounts of heat try to get to the surface, which is why there is liquid lava and a lot of volcanic activity.
