m83 galaxy

Situated in constellation Hydra, it is the southernmost galaxy in Messier's catalog.


While the radio data highlight the galaxy’s long, octopus-like arms stretching far beyond its main spiral disk (red), the ultraviolet data reveal clusters of baby stars (blue) within the extended arms. The Southern Pinwheel Galaxy, also known as Messier 83 (M83), is a barred spiral galaxy located in Hydra constellation.. M83 lies at a distance of 15 million light years from Earth. From Gamma it is about a fistwidth northwest from Pi about a fistwidth southwest. The Equinox 2000 coordinates are RA= 13h 37m, Dec= -29° 52´ which makes M83 best seen during the spring. The image show clumpy, well-defined spiral arms that are rich in young stars, while the disc reveals a complex system of intricate dust lanes. The bar funnels material to the galaxy’s center, where the most active star formation is taking place. Acknowledgement: Mischa SchirmerMessier 83 location. Astronomers discovered the supernova remnant in radio wavelengths in 1981, in visible light in 1987, and only recently in X-ray. The M83 project is scheduled to launch on Monday, January 13, 2014. As David Malin (et al.) How long did Mars planetary dynamo take to turn off? Centaurus A. Messier 83 (M83), also known as the Southern Pinwheel Galaxy, is a barred spiral galaxy located in the southern constellation M83 lies at a distance of 15.21 million light years from Earth and has an apparent magnitude of 7.54. The newest picture of M83 from the Galaxy Evolution Explorer is shown at the right, and was taken over a longer period of time. Messier 83), a barred spiral galaxy located 15.21 million light years from Earth in the southern M83 is classified as somewhere between an intermediate and normal barred spiral galaxy with well formed spiral arms, dust lanes, a central bar and strong nucleus… Yet loaded with faint features. It is one of the nearest and brightest spiral galaxies, and can even be seen in binoculars. The beautiful spiral galaxy Messier 83 is located in the southern constellation Hydra (the Water Snake) and is also known as NGC 5236 and as the Southern Pinwheel galaxy. A bar of stars, gas, and dust slicing across the core of the galaxy may be instigating most of the star birth in the galaxy’s core. Gieles. About 40,000 light-years across, M83 is a member of a group of galaxies that includes active galaxy Centaurus A. The spectrum of X-rays indicates that there is a pulsar within the remnant. The image, taken in August 2009, is Hubble’s close-up view of the myriad stars near the galaxy’s core, the bright whitish region at far right.Messier Objects: Guide to the Bright Galaxies, Nebulae and Clusters Listed in the Messier CatalogueThis website uses cookies to personalise content and ads, and to analyse user traffic. M83, pictured above in a recently released photograph from a Very Large Telescope , is a prominent member of a group of galaxies that includes Centaurus A and NGC 5253, all of which lie about 15 million light years distant. It peaked at magnitude 14.2.SN 1950B peaked at magnitude 14.5 in 1950 and SN 1957D, detected about 3 arc minutes from the nucleus of M83 on December 13, 1957, reached magnitude 15.0. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered on Centaurus A, a nearby radio galaxy. This deeper view shows more clusters of stars, as well as stars in the very remote reaches of the galaxy, up to 140,000 light-years away from its core.

SN 1983N was spotted on July 3, 1983 and peaked at magnitude 12.5.In addition to the supernova events, almost 300 supernova remnants have been detected in the galaxy.Messier 83 has been a prolific producer of supernovae, with six observed in the past century. This came as a surprise to astronomers because a galaxy’s outer territory typically lacks high densities of star-forming materials. Messier 83 or M83 (also designated NGC 5236) is a spiral galaxy in the constellation Hydra. It was discovered in 1752 by the French astronomer Nicolas Louis de Lacaille.
