It is clear that one day our future may not only exist on the Earth, but also on other planets with our solar system. To find this next part of the journey NASA has been looking to space for any answers that might help us towards our expected planetary move.
This search got a little closer this week as NASA has revealed that their Hubble telescope has found a subsurface ocean within Jupiter’s biggest moon, Ganymede.
The news was revealed by a team of scientists who found evidence that underneath the moon’s ice crust their is water hiding. This is because Ganymede is the only moon in our solar system that has its own magnetic field, on top of that the moon is also connected to Jupiter’s field due to it being so close to the planet, creating the moon’s own northern lights that circle Ganymede’s northern and southern poles.
This effect is exactly what the scientists needed to find the moon’s underwater ocean, and by observing how big each aurora’s movement is with the Hubble telescope, they found out what is happening on Ganymede, revealing that there could be a 60-mile saltwater ocean underneath Ganymede’s 95 mile think ice crust.
“This discovery marks a significant milestone, highlighting what only Hubble can accomplish,” said John Grunsfeld, associate administrator of NASA’s Science Mission Directorate at NASA Headquarters, Washington. “In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth.”
NASA have also said that they will also be looking at other icy moons for other opportunities, including Titan, Europa and Enceladus.
