On April 10th, 2017, there was a special meeting in the night sky: the Moon was seen close to Jupiter and Jupiter’s four largest moons, known as the Galilean moons. Photographer Göran Strand went out and captured the beautiful photo above of the entire group in a single frame.
“It’s a very beautiful sight in the sky tonight with the Moon and Jupiter so close together,” the Swedish astrophotographer writes. “At the time for this photo (19:33 UTC) they were 1°45′ apart.”
At the bottom of the frame, from top to bottom, we see Callisto, Europa, Ganymede, Io, and Jupiter.
