  Sombrero Galaxy - Biocrawler   (Site not responding. Last check: 2007-11-03)
The Sombrero Galaxy, also known as Messier Object 104 (M104), Spiral Galaxy M104, or NGC 4594, is a spiral galaxy in the Virgo constellation, about 28 million light years away.
The galaxy lies in the constellation Virgo, though it is not considered a member of the Virgo cluster.

 Sombrero Galaxy Poster
The Sombrero Galaxy, so named because it resembles the broad-brimmed Mexican hat, is one of the most famous objects in the sky.
The light from this remarkable spiral galaxy is dominated by the billions of old, faint stars that form the vast "bulge" around its tiny, hidden nucleus.
The effect is enhanced because the disk of the galaxy is seen edge on, and dust in the outer parts of the disk is seen in silhouette.

A dramatic new image of the Sombrero galaxy has been obtained by the third large telescope to be commissioned at the Paranal Observatory in the Andes.
Astronomers call the galaxy the Sombrero because of its resemblance to a Mexican hat and have a special affection for it - it is often seen adorning the walls of observatories and universities all over the world.
The smallest galaxy at the center of the image could be related to the other three or an unrelated background object, she said.

 Hubble Mosaic of the Majestic Sombrero Galaxy
The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy.
This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat.
The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns.

 Sombrero Galaxy (M104, NGC 4594)
A type Sa spiral galaxy in the constellation Virgo whose unusually large central bulge, richly populated with several hundred globular clusters, and dark prominent dust lanes give it the appearance of a Mexican hat; we see it from about 6° south of its equatorial plane.
Discovered by Pierre Méchain in 1781, it became the first galaxy for which a large redshift (equivalent to a recession velocity of about 1,000 km/s) was found, by Vesto Slipher in 1912.
Modern studies have shown the Sombrero to have both a very extended faint halo and a mildly active nucleus indicative of the presence a central supermassive fl hole.

The colour image was made by a combination of three CCD images from the FORS1 multi-mode instrument on VLT ANTU, recently obtained by Peter Barthel from the Kapteyn Institute (Groningen, The Netherlands) during an observing run at the Paranal Observatory.
This galaxy is notable for its dominant nuclear bulge, composed primarily of mature stars, and its nearly edge-on disk composed of stars, gas, and intricately structured dust.
A significant fraction of the galaxy disk is even visible on the far side of the source, despite its massive bulge, cf.

This galaxy was involved in the early measurements of red shift begun at Lowell Observatory in 1912.
These measurements demonstrated that the galaxy was receding from us at a high speed of 700 miles per second, and provided strong support for the theory that it was an object outside our own galaxy.

Sombreros usually have a somewhat high tip and a very wide brim, used for protection from the sun.
Cowboys of the American southwest later adopted the sombrero and modified it into the cowboy hat.
Various functions and distributions encountered in mathematics and the physical sciences show a peak within a depression when plotted, and are thus referred to as a "Mexican hat" by analogy with the shape of a sombrero.

 Seyfert galaxy concept from the Astronomy knowledge base
The central region of a Seyfert galaxy is distinguished by powerful radiation, much of it focused into narrow frequencies.
has definition One of a small class of galaxies (many of which are spirals) of very high luminosity and very blue continuum radiation with small, intensely bright nuclei whose spectra show strong, broad, high-excitation emission lines probably caused by discrete clouds moving at velocities that are higher than the escape velocity.
The energy sources in their nuclei are unexplained; presumably the energy input can be associated with some process that liberates gravitational binding energy to accelerate relativistic particles.

The Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred Sa spiral galaxy in the constellation Virgo.
The Sombrero Galaxy was discovered in 1781 by Pierre Méchain, who described the object in a May 1783 letter to J. Bernoulli that was later published in the Berliner Astronomisches Jahrbuch.
However, it is unclear as to whether the Sombrero Galaxy is part of a formal galaxy group.

This galaxy is a classic in just about any size instrument, provided you have access to dark skies.
The Sombrero galaxy (Messier 104) lies some 40 million light years distant and is named for the appearance that comes about from a dark lane of dust that cuts lengthwise across the galaxy.
In this size scope, the galaxy will often take on the appearance of being cut off sharply on one side, rather than split down the middle, depending on the visibility the southern bulge.
