Júpiter vai ficar "sem luas", Na noite de 3 setembro de 2009
Na virada da noite de 2 para 3 setembro de 2009, um acontecimento notável celeste terá lugar. Júpiter vai ficar "sem luas".

On the night of September 2-3, 2009, a remarkable celestial event will take place. From 4:43 to 6:29 Universal Time on the 3rd (which is 12:43 to 2:29 a.m. EDT on the 3rd, or 9:43 to 11:29 p.m PDT on the 2nd), a casual look at Jupiter through a telescope will show no moons at all. It's quite common for one of the four Galilean moons be hidden, and it's not rare to see only two moons. But only a few times in a century do all four moons hide simultaneously behind or in front of Jupiter.
