Near-Perfect Symmetry Revealed in Red Cosmic Square Ker Than

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.

Interesting info on this potential target planet....

If made of rock as they suspect, its likely 1.5 times the size of Earth

Gravity is 1.6 times stronger than on Earth

It likely doesn't rotate on an axis like Earth does, so one hemisphere would be lit 24/7.

Speaking of time, judging by the wobble of the star, 581c orbits its host star every 1.9 Earth days.

It is 14 times closer to Gliese 581 than we are to the sun, meaning the star would appear in the sky nearly 20times larger than the moon does here.

Being that much closer doesn't have the profound effect on surface temperature that you might think. Gliese 581 is a Red Dwarf. Red Dwarf Stars are much smaller and cooler than our sun. Surface temps are estimated to be as low as our temperate climates and as high as 400 degrees Farenheit.
