Early on the morning of May 17, a thin, waning crescent moon will rise in the east and will be hiding a surprise: Jupiter will appear from behind the moon’s dark edge at 4:23 a.m. This will occur while the moon is near the true horizon, which means you will need a very clear view to the east to see it. If you have a telescope, you can also watch two of Jupiter’s moons emerge from behind our moon starting around 4:11 a.m.
