A mysterious 'black hole' appeared on the largest planet in the Solar System

The photo taken of Jupiter startled viewers because of a very large black streak, appearing on the surface of this planet like a "hole". 

In an image taken from NASA's Juno spacecraft, a mysterious "black hole" was suddenly observed on the surface of Jupiter - the largest planet in the Solar System.

This is actually the black shadow of Ganymede moon.

However, reality is not as scary as you think. This is not a hole, but just the shadow of Ganymede - Jupiter's largest moon left on its journey.

Ganymede is also the largest moon in the Solar System, more than Pluto, with a radius of 2634.1 km. In the past, Ganymede was even considered a planet.

Ganymede is composed mainly of silicate rocks and ice. But recently, scientists have discovered the appearance of the magnetosphere on this moon. They also believe that between the layers of ice on Ganymede is a thick sea of ​​salt water, located about 200 km deep in the satellite's heart.

According to NASA, to capture this stunning image, Juno spacecraft flew at a distance of 71,000 km from Jupiter's surface, about 15 times closer than Ganymede's orbital distance of 1.1 million km. "JunoCam captured this image from very close to Jupiter, making Ganymede's shadow appear particularly large," NASA said.

NASA also shared that the Juno spacecraft is on a long-term mission to understand Jupiter's weather and dynamics. Studying this planet from a close distance allows scientists to understand how large planets might behave in other Solar Systems.
