Fearful symmetry.

The image is of the Red Square Nebula, recently discovered in the constellation Serpens by astronomers using the Palomar and Keck telescopes in California and Hawaii, respectively. Credit for the photograph, which I downloaded from AOL News, goes to Peter Tuthill of Sydney University and Palomar/Keck; James Lloyd of Cornell University is credited as co-discoverer of the Nebula.

Like the Helix Nebula featured in an earlier post, the Red Square is debris from a dying star; however, it's very neatly distributed debris. You can read more about it in New Scientist here.
