A few nights ago I noticed that Jupiter was once more visible from my window. This is after many months of silence and to see its bright spot on the horizon was an immediate excitement. The moon was also nearby, with its disk growing larger each night. On that night I pointed my telescope at Jupiter and saw its Galilean moons once again: Europa, Io, Callisto, and Ganymede. The first three were bunched together on the right of Jupiter (from Earth’s perspective) and were not easily differentiated from Jupiter’s glare. Ganymede was visible, however, and I managed to take a photo of the system which was clear enough to isolate the large moon’s grey-white surface:
I was amazed at how the moon’s surface colors were visible. I wonder how much clearer this image would be outside of the city!
