Messier 81 is a grand design spiral galaxy located in the constellation Ursa Major. It is also known as Bode's Galaxy and lies at an approximate distance of 11.8 million light years from Earth. Messier 81 contains 250 billion stars with a supermassive black hole at the centre. Messier 81 has two well resolved spiral arms that contain large quantities of interstellar dust,associated with numerous starburst regions. The hot,young,blue stars in the star forming regions of Messier 81 heat the dust,increasing the emissions from these regions. This image was taken by the NASA/ESA Hubble Space Telescope. | |
