Description

Messier 106 (bright galaxy at left-center and also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici.  M 106 is at a distance of about 22 to 25 million light-years away from Earth.  It is one of the largest and brightest nearby galaxies, similar in size and luminosity to the Andromeda Galaxy.  M106 contains an active nucleus classified as a Type 2 Seyfert, and the presence of a central supermassive black hole has been demonstrated from radio-wavelength observations of the rotation of a disk of molecular gas orbiting within the inner light-year around the black hole.  NGC 4217 (bottom-center) is a possible companion galaxy of Messier 106.  A Type II supernova was observed in M106 in May 2014.

NGC 4248 is the galaxy at the center of the image with the twin galaies NGC 4231 and NGC 4232 just right.  The right upper corner contains galaxies NGC 4218 and NGC 4220.  

The appeal of this image to me, in addition to the raw beauty of M 106, is in the framing of multiple galaxies.  The distances and time involved serve to remind me of the wonder that is life.  So many stars, so many planets, so much time....
