M108, NGC3556

January 26, 2005
M108 is a type Sc spiral galaxy in the constellation Ursa Major. Almost edge-on, it shows little or no bulge and no noticeably strong center, being a motley collection of features often referred to, in classic understatement, as very dusty. The spiral structure is not very clearly delineated, unsurprisingly. M108 is around 40 to 50 million light-years away in a loose galaxy grouping which includes M109 and possibly M106. This picture was created from observations using the T2KA CCD camera at the Kitt Peak National Observatory's 0.9-meter telescope in January of 1997.
