Jupiter and the Shadow of Three Moons Were Quite the Spectacle on Friday Night

Did you miss out on three of Jupiter’s largest moons casting shadows on the gas giant? Check out this animation of the triple moon shadow transit from the Griffith Observatory.

The first moon casting its shadow on Jupiter is Callisto, followed by Io and Europa. The triple shadow transit lasted just 25 minutes, but it was an amazing sight for those of you who were able to catch it.

If you did miss it, you will be waiting until 2032 for it to happen again.

Here’s another video showing what the transit looked like through a telescope.

A Few Facts About Jupiter’s Moons

The gas giant has 67 moons.

51 of these are small, coming in at 10 kilometers in diameter. They are also recent discoveries with all of them being discovered since 1975.

The Galilean moons are Io, Europa, Ganymede, Callisto. The four were discovered by Galileo Galilei in January 1610.

Galileo didn’t actually come up with the moon names we use today. That honor went to Simon Marius, who independently discovered the moons around the same time as Galileo. Johannes Kepler, another key astronomer in the 17th century, suggested the names to Marius who published them in his Mundus Jovialis in 1614.
