There are a lot of things in Earth's night sky, and every now and again, they line up in such a way to give us all a little bit of a giggle. On the nights of Thursday 24 and Friday 25 April, just such an alignment is going to take place,

According to Culbertson, Venus will be the higher of the two “eyes” while Saturn will be the lower, and the thin, crescent moon grin will appear slightly lower and farther north. The smile will be visible to the naked eye, although a backyard telescope or pair of binoculars should allow you to get a better look at the moon’s details.
