Out past Neptune are countless small icy and rocky bodies called Trans-Neptunian Objects (TNOs), and many of these have moons as well. While some TNOs could be called dwarf planets because of their ...

There is no other moon quite like our own in the entire solar system. The Moon is unique in a lot of ways, some of which are ...

Ganymede, and Callisto. The Moon is non-luminous, meaning that it does not produce light. We see the Moon because it reflects light from the Sun, and half of the Moon’s surface is always ...

Jupiter's largest moon Ganymede is generating "killer" waves of electrons that astronomers say could damage spacecraft going on future missions. These electromagnetic waves can be found all around ...

NASA doesn't say which spacecraft recorded these weird radio emissions from Jupiter's largest moon, Ganymede, but it was likely the Galileo spacecraft (which orbited the system for about 8 years).

Ganymede lies to its southeast ... re back at Jupiter in Taurus this evening to watch the innermost Galilean moon, Io, now transit the disk alongside its shadow. Already coming around after ...

NASA announced that it has evidence that Jupiter’s moon Ganymede, the largest moon in our solar system, has a vast ocean lurking underneath its icy crust. WSJ's Monika Auger reports.

When conducting measurements, GALA sends short laser pulses down to the surface of the icy moon currently under investigation, Europa, Ganymede or Callisto. At the surface, the pulses are reflected ...

Towards the end of the mission, the JUICE probe dedicates its experiments in detail to the largest moon in our Solar System, Ganymede. The focus is on a suspected ocean under a kilometre-thick ice ...
