@skymapapp: The brightest thing in the eastern sky before sunrise. On October 3, look east in the last few hours before dawn, about two and a half fists above the horizon. Jupiter is creamy white, rock steady, and brighter than anything else up there. If you have binoculars, hold them steady — you can see up to four of its moons in a little line beside it. Same four Galileo saw. Have you ever caught Jupiter's moons with just binoculars? #stargazing #jupiter #Astronomy #binoculars #nightsky
