M101
04/04/2024

M 101 (NGC 5457), the Pinwheel Galaxy, is a type Sc spiral galaxy in Ursa Major.  Discovered in 1781 by Mechain and catalogued the same year by Messier, M 101 is one of the finest examples of a face-on spiral in the heavens.  A giant pinwheel of stars resembling the Milky Way in size and shape, this spiral appears almost face-on to our view.  M 101 has multiple spoke-like arms that extend outward to a diameter of one third degree.   The arms are dotted with bright nebulae, star clouds, and dust lanes.  At a distance of 18 million light-years, the galaxy would measure about 100,000 light-years in size.

NGC 4567 (Siamese Twins)
04/04/2024

NGC 4567 - Siamese Twins sometimes called the Butterfly Galaxies in the constellation Virgo.  These unbarred spiral galaxies are in the early stages of galactic collision and merger.  They are about 60 million light years away and it's estimated that in about 500 million years they will coalesce into a single, large elliptical galaxy.
