Topic: Spiral Galaxy M106


  
  M106   (Site not responding. Last check: 2007-11-04)
Gravitational interaction with nearby galaxies has caused this distortion, as well as triggered a bout of star formation throughout its extent, seen as brush-stroke clusters of young, blue-hot stars, and mottled pinkish patches of hydrogen gas, energized from within by yet more nascent suns.
M106 belongs to an intriguing class of objects known as active galaxies.
In M106, these jets are apparently directed into the main disk of the galaxy, and the jets of matter ram into material in the disk.

 m106
M106 is approximately 25 million light years from the Earth and is located in the constellation Canes Venatici and very close to the better known constellation of Ursa Major.
M106 is intermediate between a "barred" spiral and a "normal" spiral galaxy which gives it a very eye-catching appearance.
It is a very active galaxy and shines extremely bright in the radio as well as the high energy portion of the spectrum and is thus classified a "Seyfert" galaxy.

This is an example of "multiple arm" spirals due to two apparent sets of arms, one close in to the center, and the outer, looser set.
Spiral galaxy M90 was discovered by Messier in 1781 and is about 80,000 light years across.
M106 is a fine spiral galaxy about equal in mass to our own Milky Way, 160 billion solar masses.

 M106 Galaxy
The core of the galaxy exhibits prominent x-ray and radio emissions, and twin jets have been found along the length of the galaxy.
At 25 million lights years away, M106 is the closest example of a Seyfert galaxy, where large amounts of gas are thought to be falling into a massive fl hole in the center of the galaxy.
The other smaller galaxy in the field to the lower right of M106 is NGC 4248, a 12.7v magnitude spiral galaxy about 3 x 1 arc minutes in size.

 M106   (Site not responding. Last check: 2007-11-04)
While M106 is usually classified as peculiar "normal" spiral of type Sb (or Sbp), Tully classifies it as SABbc, i.e., intermediate between Sb and Sc, and intermediate between normal and barred spirals.
These knots are most probably young star clusters which are dominated by their very hot, brightest and most massive stars; the occurrence of these hot stars indicates that these clusters cannot be very old, as such massive stars have only a short lifetime of a few million years.
In 1943, Carl K. Seyfert had listed this galaxy among the galaxies with emission line spectra from their nuclei, which are now called Seyfert galaxies, but modern studies of Seyfert galaxies normally do not include it.

A NASA image of a spiral galaxy, one of the main classes of galaxy, of which Andromeda and our own Milky Way are examples.
Spiral galaxies are characterized by a central bulge surrounded by a flattened disc containing (normally) two spiral arms composed of hot young stars and clouds of dust and gas.
In about half of spiral galaxies (barred spirals) the arms originate at the ends of a bar across the central bulge.

 Canes Venatici - Wikipedia, the free encyclopedia
One of the more significant galaxies in Canes Venatici is the Whirlpool Galaxy, M51 (NGC 5194 and NGC 5195), a spiral galaxy that is seen face on.
This was the first galaxy recognised as having a spiral structure, this structure being first observed by Lord Rosse in 1845.
The companion galaxy (top of picture) is being disrupted by the gravitational forces of M51.

M106 (NGC 4258) is a Sb spiral galaxy in the constellation Canes Venatici.
M106 is around 25 million light years away and may be a member of a loose galaxy grouping which includes M108 and M109, although some have placed it in a different group.
A somewhat peculiar spiral, sometimes considered to have hints of a bar, M106 is also a Seyfert galaxy, showing strong emission lines in spectra of its nucleus.

Nevertheless, only few modern studies of Seyfert galaxies include it, although its nucleus is classified as Seyfert 1.9, according to the NED data of this galaxy.
M106 is one of Pierre Méchain 's findings, which were later appended as additional objects to Charles Messier 's catalog.
In case of M106, it was Helen Sawyer Hogg who added it together with M105 and M107 in 1947, but it appears reasonable to assume that already Méchain had intended to add it to a future edition.
