NASA’s Astronomy Picture of the Day

In today's image, we see an image of an astronaut floating free in space. He is using a Manned Maneuvering Unit (MMU) Which allows the astronaut to move in space, untethered to the spacecraft.

In today's image, we see the supernova remnant Cassiopeia A. This would have been seen to explode back in the mid-late 1600s but was never definitively observed - perhaps because of excess dust in the region.
