M101 - The Pinwheel Galaxy
In the constellation of Ursa Major, at about 25 million light years from us lies the Pinwheel Galaxy. This beautiful galaxy has 170,000 light years across, about twice of our Milky Way.
In the photo, two types of color clusters hint on the objects present: the red-pinkish ones are the hydrogen rich nebulas where star forming is taking place and the blue ones on the spiral arms are clusters of young and hot blue stars.
This photo is a cropped reprocessing of my previously published photo.
Shot at Santa Susana, Portugal on Mar.26th and Barcarena, Portugal on Apr.1st and Apr.28th 2022.
