Title:
Starburst Galaxy M94
Explanation:
What could cause the center of M94 [ http://sirtf.caltec…] to be so bright? Spiral galaxy [ http://antwrp.gsfc.…] M94 has a ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow. A leading progenitor hypothesis [ http://adsabs.harva…] holds that an elongated knot [ http://www.cs.ubc.c…] of stars known as a bar [ http://antwrp.gsfc.…] rotates in M94 and has generated a burst of star formation in the form of an outward moving ring. M94 [ http://www.seds.org…], pictured above [ http://www.noao.edu…] digitally sharpened, spans about 30,000 light years [ http://starchild.gs…], lies about 15 million light years away, and can be seen with a small telescope toward the constellation [ http://www.astro.wi…] of Canes Venatici [ http://www.astronom…].
