In this week’s StarDate Susitna, producer Kathleen Fleming informs listeners about the New Moon, the opposition of Jupiter, and observing Jupiter’s 4 Galilean Moons. Below is a picture of Galileo’s notes when, in 1610, he saw that Jupiter has moons! When you look for the 4 big moons in a line to the right and left of the planet, you can find out which is which by using this interactive tool from SkyandTelescope.org. https://skyandtelescope.org/observing/jupiters-moons-javascript-utility/. The link to the “interactive Jupiter’s Moons tool” is about half way down the page.
