Red Square Nebula

I'd show the picture, but it looks like the copyright might not allow that. So look here. Amazing!

Space.com reported yesterday about the new discovery, described in the April 13 issue of Science.

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.

But the Red Square isn't the only stellar object of its kind.

The researchers propose that similar conditions are contributing to the extreme symmetry of another system, the Red Rectangle, whose central star is cooler than that of the Red Square.

The new findings suggest the system's perfect form results from an even outflow of gas. 'The reason the Red Square remains so symmetrical is that there is no material that has interfered with the outflow, so it has preserved the symmetry it was born with,' Lloyd said.


Each new find (with its photos) becomes another opportunity for wonder, for breath-stopping awe. It never gets old.
