Sharpest image ever of M81

The sharpest ever image of the spiral galaxy M81 was released last week at the American Astronomical Society Meeting in Honolulu, Hawaii.
A spiral-shaped system of stars, dust, and gas clouds, the galaxy’s arms wind all the way down into the nucleus. Though the galaxy is located 11.6 million light-years away, the Hubble Space Telescope’s view is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas.
The image was captured in bits using the HST Advanced Camera for Surveys over 2004 through to 2006.
You can download the stunning image from spacetelescope.org in a number of different sizes including a monster 700Mb tiff file!
