 May 20 2009  NGC 4088 with Supernova 2009dd |
|
Spiral galaxy NGC 4088 is a member of the M109 Group of galaxies in Ursa major. It has a companion, NGC 4085, about 11 arc min to the south (just below the bottom edge of this picture).
NGC 4088 is 100,000 light years in diameter, and 60 million light years away. It is a "grand design spiral" with two distinct arms; however, one of its arms appears to have a disconnected segment. This feature has earned it a place in the Arp Atlas of Peculiar Galaxies. The NE part of the galaxy rotates more slowly than the SW part, possibly due to tidal interactions with NGC 4085.
The small galaxy at bottom left (MCG +09-20-092) is not a companion of NGC 4088. According to its red shift, this galaxy is apparently 750 million light years away.
On April 13, 2009, a very bright supernova was discovered in NGC 4088, and assigned the identifier of SN2009dd. The supernova can be seen clearly in this image, very close to the galaxy's core.
This was my first image using www.MyTelescope.com. It is composed of 19 stacked images, each 30 seconds long. Binning was set at 2 x 2. I would like to thank Michael and Glynn of "My Telescope" for their assistance and customer support with this image. |
