M82, the Cigar Galaxy

Bright M82 is fairly easy to find — once you catch on to a certain trick. Hubble views new supernova in Messier 82 [6]. Located 12 million light-years away, M82 appears high in the northern spring sky in the direction of the constellation Ursa Major, the Great Bear.

We find that these young stellar clusters have inferred masses and sizes comparable to globular clusters. We find that purely foreground extinction cannot reproduce the global relative intensities of H recombination lines from optical to radio wavelengths. In spite of its inclusion in the Messier Catalogthis peculiar galaxy was actually discovered by J. Seaquist et al explained in a study:. Most NASA images are in the public domain.

Be to sure to check out our complete Messier Catalog. In the infrared light, M82 is the brightest galaxy so far glaxy. M82 is the was discovered on the same night as M81 by Johann Elert Bode, who found the pair on December 31, Most of the pale, white objects sprinkled around the body of M82 that look like fuzzy stars are actually individual star clusters about 20 light-years across and contain up to a million stars.


Because of the relative brightness, both stand up well galasy urban lighting conditions and a great deal of Moon interference. Astronomers have postulated that this fluctuating emission comes from the first known intermediate-mass black holeof roughly to solar masses. Seen at Berlin, by M.

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. Originally mistaking these objects for comets, he began to catalog them so that others would not make the same mistake.

M82 – Cigar Galaxy

Phi, is pronounced to be double, both companions being of the 5th magnitude, and only half a second asunder. Messier 82 Alternative Designations: Seen at Berlin, by M. Once you are there, both M82 and larger, brighter companion galaxy M81 are easy to spot in a finderscope galqxy small binoculars.

Recently, over new, young globular clusters have been discovered with the Hubble Space Telescope. From detailed population synthesis and the mass-to-K-light ratio, we conclude that the near-infrared continuum emission across the starburst regions is dominated by red supergiants with average effective temperatures ranging from to K and roughly galxy metallicity.

Takahashi Epsilon Hyperbolic Astrograph Camera: M82 was first discovered by Johann Elert Bode on December 31, together with M81; he described it as a “nebulous patch”, about galaxyy. In the core of M82, the active starburst region spans a diameter of pc.

Galaxxy are several minute companions [stars] in the field, of which a close double star in the sp [south preceding, SW] quadrant is No. By using this site, you agree to the Terms of Use and Privacy Policy. With a low power, No. Saturn’s storm from Hubble. A starburst galaxy in the constellation Ursa Major.

It has an apparent visual magnitude of 8.

Stars in M82’s disk seem to have been formed in galaxj burst million years ago, leaving its disk littered with hundreds of clusters with properties similar to globular clusters but youngerand stopped million years ago with no star formation taking place in this galaxy outside the central galaxxy and, at low levels since 1 billion years ago, on its halo.

M82 is being physically affected by its larger neighbor, the spiral M
