Observations of SN 1993J have indicated that types Ib and Ic were triggered by explosions of giant stars through processes similar to those seen in type II supernovae.At the center of spiral galaxy M81 is a supermassive black hole about 70 million times more massive than our sun. 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. 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. Image: Anttler at wikipedia.orgBode’s Galaxy is the largest member of the M81 Group, a group of 34 galaxies lying in The close encounter between the galaxies occurred about 300 million years ago. Image: NASA, ESA and the Hubble Heritage Team (STScI/AURA)Bode’s Galaxy is home to over 250 billion stars. M81 is one of the brightest galaxies that can be seen from the Earth. ; IR: NASA/JPL-Caltech/CfABode’s Galaxy was named after Johann Elert Bode, the German astronomer who discovered it on December 31, 1774, along with the nearby On December 31, I found through the seven-foot telescope, closely above the head of Here we see two different views of the spiral galaxy, Messier 81. Image: Adam Block/Mount Lemmon SkyCenter/University of ArizonaSeveral other members of the M81 Group, including the With prominent, clearly defined spiral arms, Bode’s Galaxy is an excellent example of a grand design spiral. SN 2014J, a On the left is an image taken in blue light, while on the right is a specially-processed version of an image taken with the Spitzer Space Telescope’s infrared array camera (IRAC) at 4.5 microns. 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 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. Image: Hubble data: NASA, ESA, and A.

M81 Galaxy is Pretty in Pink 06.04.07 The perfectly picturesque spiral galaxy known as Messier 81, or M81, looks sharp in this new composite from NASA's Spitzer and Hubble space telescopes and NASA's Galaxy Evolution Explorer. Image: NASA, ESA and the Hubble Heritage Team (STScI/AURA)Bode’s Galaxy can easily be seen in binoculars and amateur telescopes, but is not visible to the naked eye unless viewing conditions are exceptionally good. 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. After seeing it in his large 10-foot telescope on November 26, 1810, he noted, “I viewed the nebula with the large 10 feet. Image: Anttlers at wikipedia.orgA supernova was observed in Bode’s Galaxy in 1993. As a result, all three galaxies have had hydrogen gas stripped away.
of Witwatersrand, South Africa)William Herschel observed the object a number of times. M81 is one of the brightest galaxies seen from Earth. The filaments are made of the gas that is being stripped away from the three galaxies. Located in the northern constellation of Ursa Major (which also includes the Big Dipper), this galaxy is easily visible through binoculars or a small telescope. A member of the M81 Group, it is about five times more luminous than the whole Milky Way and has a center one hundred times more luminous than our galaxy's center. 82 M. can be brought into the north part of the same field of view, although they are half a degree apart.

The galaxy is similar to our Milky Way, but our favorable view provides a better picture of the typical architecture of spiral galaxies.
Further processing using a mathematical technique called Fourier filtering allowed the team to pick out structures on the physical scale on which star formation occurs, revealing these streams of young stars flowing away from their stellar nurseries. A study using data from Chandra and ground-based telescopes, combined with detailed theoretical models, shows that the supermassive black hole in M81 feeds just like stellar mass black holes, with masses of only about ten times that of the sun.
M81 is located at a distance of 12 million light-years.
