Description

Distance approx. 21 million lightyears

I took the opportunity to take an image of this impressive spiral galaxy. Within the spiral arms of M101 are numerous HII regions where star formation is taking place.Both the dwarf galaxy NGC5477, which is a companion galaxy of M101, and the lenticular galaxy NGC5473 can be seen in the right half of the image.
