NASA’s Hubble Space Telescope has the best evidence yet for an underground saltwater ocean on Ganymede, Jupiter’s largest moon. The subterranean ocean is thought to have more water than all the water ...

First, my apologies. I so wanted to alert you to the half moon's pass of the bright star Aldebaran last night. But there were network problems with the blog, and I wasn't able to post. No doubt many ...

The ocean on Ganymede may have more water than all the water on Earth. In this artist’s concept, the moon Ganymede orbits the giant planet Jupiter. NASA’s Hubble Space Telescope observed aurorae on ...

Last year, JWST made spectral observations of Ganymede and infrared observations of Io. Absorption lines of hydrogen peroxide at Ganymede's poles indicate radiolysis of water ice by charged particles ...
