Speaking of telescopes..

As I was saying.. Galileo wasn’t able to describe the four satellites of Jupiter other than noting moving points of light, but when you’re whizzing past them with a battery of modern scientific devices you can get a much better view. Nasa’s New Horizons mission is heading further out towards the dwarf planet Pluto [that’s not a real planet – Ed], although it was a fully fledged planet when they started, and they’ve been testing out the onboard equipment while passing through Jupiter’s backyard.They also took some very nice images of Io.. moving ones too

Jupiter’s Little Red Spot

And Galileo’s moving points of light.. aka Io, Europa, Ganymede and Callisto.
