NASA's Chandra X-ray Observatory has released four stunning images of cosmic wonders, depicted in red, white and blue to coincide with the United States' 250th anniversary on July 4.

The four images reveal superheated gas in a distant galaxy cluster, the swirling spiral galaxy known as Messier 94, a glowing nebula found in our own Milky Way galaxy, and the Cassiopeia A supernova remnant, respectively.
