M33 Pinwheel (Triangulum) Galaxy from DSC Headcorn
|
M33, known as the Pinwheel Galaxy or the Triangulum Galaxy is a face-on galaxy located relatively close to the Milky Way at approximately 2.3 million light-years, in the Constellation Triangulum. It can be seen in binoculars as a faint glow as its light is spread out over a large field of view. M33 is a member of our local group of galaxies, the third largest at 50,000 light-years in diameter, and is probably a satellite galaxy of M31, the Andromeda Galaxy. M33's galactic arms appear turbulent with many HII regions, glowing in red, and hot blue stars, which high resolution images bring out nicely.
