Spiral Galaxy NGC 918 and Supernova 2009 js
Image taken with an STL-1301E CCD camera thru Kopernik's 20 inch F/8.1 telescope at 00:20 UT on November 18, 2009. The field of view is 12x15 arc minutes with North at the top.


Supernova 2009 js:

Discovered November 6th, 2009, by Koichi Itagaki and the Lick Observatory Supernova Search group.

Follow this Link to a NASA Web site on supernovas. It has a very nice animation and a description of what these objects are.


Spiral Galaxy NGC 918:

Spiral Galaxy NGC 918 is in the Constellation of Aries. The galaxy has a small galaxy and perhaps a small bar. There are two main spiral arms and at least one minor arm. There's a very bright foreground star just north of the nucleus. A rough distance estimate for NGC 918 is 61 million light years.

Reflection Nebulosity: The large patchy dim areas that extend throughout the Kopernik image is an area of reflection nebula resulting from thin dust clouds above the plane of the Milky Way Galaxy that are reflecting the starlight of the galaxy.
