And not only is the nucleus a fascination, but the smooth spiral structure as well. After all, look at how many stars it gathered in when the two combined! This nebula is a little oval, the center clear, and one can see it well in an ordinary telescope of 3.5 feet.”, All historical observers note the bright nucleus, but to for Emil Dreyer to give it an exclamation point in his own personal notes is a rarity… says he: “Remarkable, extremely bright, extremely large, extended in position angle 156 degrees, gradually, then suddenly very much brighter toward the middle where there is a bright nucleus.”. Creative Commons Attribution 4.0 International License. The gravitational influence of M81 has left all three galaxies stripped of hydrogen gas. SN 1993J was the only supernova observed in Messier 81. M82 or the Cigar galaxy, shines brightly at infrared wavelengths and is remarkable for its star formation activity. Image: NASA, ESA and the Hubble Heritage Team (STScI/AURA). As Ioannis Bagetakos (et al) explained in a 2007 study: “The data show a stunning amount of detail in the form of 330 expanding shells and holes in the neutral ISM of M81. M110 is a satellite of the much larger Andromeda Galaxy (M31). The unprecedented spatial resolution and sensitivity of Spitzer at infrared wavelengths show a clear separation between the several key constituents of the galaxy: the old stars, the interstellar dust heated by star formation activity, and the embedded sites of massive star formation. Bode’s Galaxy, also known as Messier 81 (M81), is a grand design spiral galaxy located in the constellation Ursa Major. At one time, several billion years ago, the pair interacted with each other. Amateur astronomy. 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. This 22-second animation uses an "infrared spotlight" to highlight differences between a visible-light image of Messier 81 and the Spitzer/MIPS+IRAC infrared view. This image reveals M81's bright yellow nucleus, blue spiral arms, pink starforming regions, and … One of the brightest galaxies in planet Earth's sky is similar in size to … Easy to assemble. Due to this, it is sometimes referred to as "Bode's Galaxy". Type: SA(s)ab This beautiful galaxy is tilted at an oblique angle on to our line of sight, giving a “birds-eye view” of the spiral structure. 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. $894.81. Messier 81, also known as NGC 3031 or Bode's Galaxy, is a grand design unbarred spiral galaxy located approximately 11.8 million light years away from Earth in the constellation of Ursa Major. A comparison with the holes found in two other spirals and two dwarf galaxies reveals that the ISM in M81 shares a lot of similarities with the two spirals, whereas the structure of its ISM is different to that in dwarf galaxies. 4.1 out of 5 stars 2,008.

John A Read. During the 18th century, famed French astronomer Charles Messier noticed the presence of several “nebulous objects”  while surveying the night sky. The hot, young blue stars heat the dust, increasing the level of emissions in the infrared. Our observations reinforce the idea that the amount of energy typically deposited in the ISM is the same, irrespective of galaxy type, but that the properties of HI holes depend on the characteristics of the host galaxy, notably the thickness of the neutral gas layer.” “Also, there seems to be a clear indication that HI holes in spiral galaxies are shorter-lived, most likely due to the combined effects of shear and spiral density waves.”. 4.6 out of 5 stars 1,737. I did log it as "difficult," which proves the importance of experience. It is one of the most distant permanent objects that can be viewed with the naked eye.
