Tycho's Supernova Remnant
What looks like a cell floating in a starry petri dish is the remnant of a supernova that exploded in 1572, and was witnessed by Danish astronomer Tycho Brahe (who not only had a gold-and-silver replacement nose, but a pet elk who liked to drink beer). This image is a composite of data from the Chandra X-Ray Observatory and Spitzer.
