Dying Star Bursts in Near-Perfect Symmetry

If symmetry is a sign of splendor, then the newly discovered Red Square nebula is one of the most beautiful objects in the universe.

Seen in the infrared, the nebula resembles a giant, glowing red box in the sky, with a bright white inner core. A dying star called MWC 922 is located at the system’s center and spewing its innards from opposite poles into space. (A nebula is an interstellar cloud of gas, dust and plasma where stars can both emerge and die.)

“This spectacular event is the death of a star,” said study team member James Lloyd of Cornell University.

After MWC 922 ejects most of its material into space, it will contract into a dense stellar corpse known as a white dwarf, shrouded by clouds of its own remains.

The Red Square nebula discovery is detailed in the April 13 issue of the journal Science.
