Papillon Galaxy (IC 708), Steve Biegun

Papillon Galaxy

The Papillon Galaxy is elliptical with a 14th magnitude. Papillon is a small and round spot that looks hazy because of it's bright core. The galaxy is given the french term for "butterfly," because of it's large bipolar shape. It was discovered by M Heydari-Malayeri at the Paris Observatory fairly recently. It is roughly about 2 light years wide.

The angular size of the galaxy is 0.393 arc minutes. It is roughly 170,000 light years away, and the linear size is 1.14 light years. It is as a small hazy could in this picture because the bright core is shrouded in dark dust and glowing gas. Closer, however, the galaxy is distinctly red from emissions of hydrogen and slightly yellow from ionized oxygen. This is an image that shows early star birth in progress. The bipolar shape might be caused by gas thrown out of massive tars in the middle of the gaseous cloud. The intense heat of the stars radiates and pushes the gas in opposite directions.
