Moons of Jupiter

Around 6:45 last night, while I was quietly doing some reading before dinner, Professor Shank came running into the library to announce, "I've got the telescope out and there's a clear view of Jupiter and four of its moons. You've gotta come see this!" So along with about eight other students, I grabbed my coat and headed out to the garden with the professor. With the naked eye there was a clear view of Jupiter just below the bright moon. He first adjusted the telescope to get a glimpse of the moon, and the magnification was enough so that you could see craters. Then we took a look at Jupiter and you could see four tiny dots surrounding it. 400 years ago this month Galileo observed exactly what we did, from the same city, with a telescope of the same magnification, and was the very first to do so! How cool!?
