NGC4656

Unusual Spiral Galaxy in Coma

Uploaded 6/20/2001

This peculiar edge on spiral galaxy boasts massive star forming regions and few if any resolved HII regions. This 11.0 magnitude object is 15' x 3' in size, and as seen here, the color in the central regions is more greenish from the combined light of populations I and II stars, gradiating to blue to the upper right. This was confirmed in the Wray Atlas, which barely recorded this low surface brightness object. I couldnt see this object visually in the 80mm finder, even at high power, which usually shows many galaxies faintly. Note the small yellow colored spiral to the right complete with tiny little arms in a face on orientation. I
