  APOD: 2007 March 14 - Barred Spiral Galaxy M95
First and foremost, M95 is one of the closer examples of a big and beautiful barred spiral galaxy.
USA, are sprawling spiral arms delineate by open clusters of bright blue stars, lanes of dark dust, the diffuse glow of billions of faint stars, and a short bar across the galaxy center.
What intrigues many astronomers, however, is the circumnuclear ring around the galaxy center visible just outside the central bar.

  * M95 - (Astronomy): Definition
This impressive barred spiral galaxy in Leo was discovered by Mechain in March 1781 and Messier observed it on the 24th of that month.
M95 était l'une des galaxies retenues dans le projet clé du en vue de la détermination de la constante de Hubble: le HST a été utilisé pour rechercher des variables Cépheïdes et en déduire la distance de cette galaxie.
The spiral galaxies M65, M66, M95, M96, and the elliptical galaxy M105 are nearby.

 Spiral (and other Disk) Galaxies
spiral galaxies often have an ellipsoidally formed "bulge" which may be very luminous (as in case of the Sombrero galaxy M104) or rather inconspicuous; some spirals seem to lack this component at all.
Spiral galaxies, "normal" and barred, with conspicuous bulges (especially near their center) are classified "Sa" or "SBa", those which have prominent bulges and pronounced arms are clssified "Sb" or "SBb", and those which are dominated by the arms are "Sc" or "SBc".
Some of the galaxies, mostly those who had no closer encounters for a longer period of time, and those who have lost most of their interstellar matter for some reason, do not show any conspicuous pattern within their disks; these are often called "S0" or "lenticular" galaxies.

 Barred spiral galaxy at AllExperts
A barred spiral galaxy is a spiral galaxy with a band of bright stars emerging from the center and running across the middle of the galaxy.
Spiral arms appear to emerge from the ends of the "bar" in these galaxies, whereas they appear to emerge directly from the core in ordinary spiral galaxies.
When observing a distant spiral galaxy with a rotational axis perpendicular to the line of sight, or one that appears "edge-on" to the observer, the shape of the bulge can be easily observed, and therefore quickly classified as either a barred spiral or a regular spiral.

The central bulge of the Galaxy is a dense cluster of older stars that are predominantly of spectral class M. Splaying out from the central bulge is a series of "arms" of younger stars that are of all spectral classes.
However, the gravitational attraction of the Galaxy itself holds a spherical influence, and although the majority of the material is in the disk, there is a "halo" of objects called globular clusters that independently orbit the central bulge.
As a spiral arm of stars and gas catches and moves through a density wave, the gas clouds are affected in such a manner that new stars collapse from them.

 Galaxies
Galaxies are large systems of stars and interstellar matter, typically containing several million to some trillion stars, of masses between several million and several trillion times that of our Sun, of an extension of a few thousands to several 100,000s light years, typically separated by millions of light years distance.
The most massive galaxies are giants which are a million times more massive than the lightest: Their mass range is from at most some million times that of our Sun in case of the smallest dwarfs, to several trillion solar masses in case of giants like M87 or M77.
Our Milky Way Galaxy, a spiral galaxy, is among the massive and big galaxies with at least 250 billion solar masses (there are hints that the total mass may even be as large as 750 billion to 1 trillion times that of the Sun) and a disk diameter of 100,000 light years.

 A Map of the Milky Way
The reason why the arms of spiral galaxies are so prominant is that the brightest stars are found in the spiral arms.
Spiral arms are the major regions of star formation in spiral galaxies and this is where most of the major nebulae are found.
The first good map of the spiral form of the Milky Way was produced by Oort, Kerr and Westerhout in 1958 (an early version of their map exists here.) They mapped the neutral hydrogen (HI) in the plane of the Galaxy.

 Galaxy Hopping Though Leo the Lion
Galaxies of course are usually much harder both to locate and to catch much detail.
You may even be able to see both galaxies in the same field of view if your eyepiece has that much coverage by placing M105 at one side in the field of view and looking to the south-south-west.
You won’t have to go far from M96 to find its neighboring galaxy, M95, since it is about 1 or 2 fields of view away in your telescope.

 Galaxies
Spirals, on the other hand, have retained much of their gas and are continuing to form stars.
It has become apparent that collisions, both between galaxies themselves and between the fragments that conglomerated together to build galaxies, are important in the formation/evolution of galaxies.
The idea of this "bottom-up" accumulation of larger galaxies from smaller fragments is also supported by current calculations of the formation of structure in the early Universe.

Near the center of this galaxy, the sky would be dominated by this object, and full with the members of this galaxy, while at the edges, only one hemisphere would be filled with them, the other showing only few outlying stars and the intergalactic space.
The galaxy is nicknamed the Whirlpool because of its swirling structure.
The galaxy’s spirals are believed to have been deformed by close encounters with its neighbors.

M95 is a spiral galaxy, in Leo discovered by Pierre Méchain on 20th March 1781, and catalogued by Charles Messier four days later.
Messier described it as a "nebula without star, in the Lion [Leo], above star 1 (53 Leonis): its light is very faint.." It is one of several galaxies in Leo which comprise the M96 group, and includes Messier objects M96 and M105.
M95 was one of the key galaxies used by the Hubble Space Telescope in determining the value of the Hubble constant.

Sure there are galaxies to be seen at any time of the year, but as Leo arrives on the scene, the number and diversity of galaxies grows considerably.
The galaxy is believed to be an outer member of the massive Virgo Cluster of Galaxies which we'll visit again in a few weeks.
Since each of these galaxies are visible simultaneously, and all three of these galaxies are within a 1/2 magnitude range, this is a great view to study the contrasting appearance of galaxies.

 A Map of the Milky Way
The first method is to study the density of the neutral hydrogen (HI) in the plane of the Galaxy which is enhanced in the spiral arms.
These various maps can be analysed to show the precise spiral form of the Galaxy, see Jacques Vallée's various studies of the Milky Way (1, 2, 3).
Galaxies do not have precise boundaries - the stars slowly become less plentiful as you move away from the galaxy.

 M 95
M95 was one of the galaxies in the key project of the Hubble Space Telescope for the determination of the Hubble constant: the HST was employed to look for Cepheid variables and thereby determine this galaxy's distance.
This is in semi-good agreement with the value of about 41 million light years (after correction for Hipparcos results) which had been obtained earlier by Nial R. Tanvir for its neighbor M96, and implies a distance of all the galaxies in the Leo I or M96 group of about 38 million light years.
Messier observed M95 on March 23th, 1781 "Nebula without a star in Leo, above the star l (53 leonis).
