Each of these arclets represents a young star stream in the disk of the galaxy. Its major axis lies np [north preceding, NW] to sf [south following, SE]; and it certainly is brightest in the middle. Charles Messier, (born June 26, 1730, Badonviller, France—died April 12, 1817, Paris), French astronomer who was the first to compile a systematic catalog of nebulae and star clusters. [23] At approximately 11.7 Mly (3.6 Mpc) from the Earth, it makes this group and the Local Group, containing the Milky Way,[23] relative neighbors in the Virgo Supercluster. Messier 81 (M81) sau NGC 3031, cunoscută și sub numele de Galaxia lui Bode, este o galaxie spiralată aflată la aproximativ 12 milioane de ani-lumină, în constelația Ursa Mare. Messier 87 Galaxy Facts. 8-inch and larger telescopes are required to make out the spiral structure in M81. Messier 81 (M81, NGC 3031) in Ursa Major is one of the most conspicuous galaxies in the sky, and one of the nearest beyond the Local Group. The galaxy is sometimes called "Bode's Galaxy". The galaxy lies at an approximate distance of 11.8 million light years from Earth and has an apparent magnitude of 6.94. Messier 62 The latest encounter is thought to have occurred around a hundred million years ago, during which Messier 82, as the smaller of the two galaxies, was significantly disrupted. Dubhe. The magnificent spiral arms of the nearby galaxy Messier 81 are highlighted in this NASA Spitzer Space Telescope image. Toggle Navigation . A line drawn through three stars in the sp [south preceding, SW] to a fourth in the nf [north following, NE] passes directly through the nebula. In 1991-92, he earned his second Hart Memorial Trophy and Ted Lindsay Award. At an apparent magnitude of 6.8 it is just at the limit of naked-eye visibility. Messier 8: Lagoon Nebula There are 21 stars located in the constellation of Ursa Major, which host planets. Messier 52 Messier 60 Willner (Harvard-Smithsonian Center for Astrophysics. The galaxy’s size and proximity  – it is one of the nearest galaxies beyond the Local Group – often make it a target of study by professional astronomers, while amateur astronomers and astrophotographers like to observe the galaxy because it is large and has a relatively high brightness. The M81 Group includes the Cigar Galaxy (Messier 82) and NGC 3077, two galaxies that are strongly affected by their large neighbour. Due to this, it is sometimes referred to as "Bode's Galaxy".

Messier 81 triggering starburst. It has the designation NGC 3556 in … Messier 81 has two well resolved spiral arms that contain large quantities of interstellar dust, associated with numerous starburst regions. Messier 71 Colour composite of Messier 81 from images obtained with Hubble's Advanced Camera for Surveys. Messier 82: Cigar Galaxy Admiral William Henry Smyth observed M81 in March 1837 and offered the following description: No. The hot, young, blue stars in the star forming regions of M81 heat the dust, increasing the emissions from these regions. The central bulge of this galaxy is significantly larger than the Milky Way 's bulge. Messier 81 was discovered by Johann Elert Bode in 1774. Bode’s Galaxy has 70 globular cluster candidates, detected in 1995, and an estimated total number of about 210 globulars. Toggle Navigation.
