Above are the discovery images for one of Jupiter's newest moons S/2011 J2. You can see the motion of the satellite over 40 minutes between the two exposures while the background stars and galaxies do not move. Images courtesy of Scott Sheppard

Jupiter, the largest planet in our Solar System, has quite a bit of moons. And recently, that moon count increased after Scott Sheppard, a faculty member at the Department of Terrestrial Magnetism at Carnegie Institution of Science, observed the satellites on the massive Magellan telescope.

Can you guess how many confirmed Jovian moons there are?

66!

Of course, that depends on who you ask. Some say more, others say less, but we’ll stick with NASA (and Jason Major!) on that one. 🙂

What does this mean for science? What will the new moons be called? Well, read more of my article on Universe Today.
