M81 may be undergoing a surge of star formation along the spiral arms due to a close encounter it may have had with its nearby spiral galaxy NGC 3077 and a nearby starburst galaxy (M82) about 300 million years ago.Messier 81 is the largest member of the M81 Group of galaxies, a group that contains 34 galaxies located in Bode’s Galaxy has 70 globular cluster candidates, detected in 1995, and an estimated total number of about 210 globulars.A distance of 11 million light years was determined in 1993 using the Hubble observations of 32 Cepheid variables in the galaxy.
The object was already too low to be seen to an advantage.”John Herschel catalogued M81 as h 649 and later added it to the General Catalogue as GC 1949. Messier 81 (M81), also known as Bode’s Galaxy, is a grand design spiral galaxy located in the constellation The galaxy lies at an approximate distance of 11.8 million light years from Earth and has an apparent magnitude of 6.94.

Though the galaxy is 11.6 million light-years away, NASA Hubble Space Telescope’s view is so sharp that it can resolve individual stars, along with open star clusters, globular star clusters, and even glowing regions of fluorescent gas. Willner (Harvard-Smithsonian Center for Astrophysics.Bode’s Galaxy’s infrared emissions mostly come from the interstellar dust found within its spiral arms. This image combines data from the Hubble Space Telescope, the Spitzer Space Telescope, and the Galaxy Evolution Explorer (GALEX) missions. The gravitational interaction has also resulted in the formation of filamentary structures in the group. As the closest starburst galaxy to Earth, M82 is the prototypical example of this galaxy type. Messier 81 (M81), also known as Bode’s Galaxy, is a grand design spiral galaxy located in the constellation Ursa Major. M81 is a "grand design" spiral galaxy, which means its elegant arms curl all the way down into its center. M81, also known as Bode's galaxy, is a large bright spiral galaxy located 11.8 million light-years away in the constellation of Ursa Major. 81 is a fine bright oval nebula, of a white colour, in the With a low power, No. The starburst activity is thought to have been triggered by interaction with neighboring galaxy M81. The Hubble data were taken at the blue portion of the spectrum. A few tens of million years ago, which is semi-recently on the cosmic time The GALEX ultraviolet data were from the far-UV portion of the spectrum (135 to 175 nanometers). M81’s active galactic nucleus contains a supermassive black hole with about 70 million solar masses, or 15 times the mass of the black hole in the Milky Way Galaxy, and has been an object of extensive study. The distance was later corrected using data from ESA’s Hipparcos satellite.Messier 81 (left) and Messier 82 (right) in visible light. (Harvard-Smithsonian Center for Astrophysics); Spitzer data: NASA/JPL/Caltech/S. This galaxy is a striking example of a grand design spiral and exhibits near perfect and well defined spiral arms.
The interaction has also caused the gas to fall into the central regions of This beautiful galaxy is tilted at an oblique angle on to our line of sight, giving a “birds-eye view” of the spiral structure.
M81 is one of the brightest galaxies seen from Earth. The infrared images also permit quantitative measurements of the galaxy’s overall dust content, as well as the rate at which new stars are being formed. The two nebulae precede Lambda, in the end of The apparent place here taken, is that of a small star between the two nebulae, which was differentiated with 29 Ursae Majoris, and every care taken in the reduction. 82 M. can be brought into the north part of the same field of view, although they are half a degree apart. Named SN 1993J, the supernova was first detected by the Spanish amateur astronomer Francisco Garcia Diaz on March 28 of that year.
The hot, young, blue stars in the star forming regions of M81 heat the dust, increasing the emissions from these regions.This beautiful galaxy is tilted at an oblique angle on to our line of sight, giving a “birds-eye view” of the spiral structure. The processed image reveals myriads of tiny arclets, a representative sample of which are arrowed.

This discovery supports Einstein’s relativity theory that states black holes of all sizes have similar properties. Bode’s Galaxy, also known as Messier 81 (M81), is a grand design spiral galaxy located in the constellation Ursa Major .
