  Messier Object 86
M86 has been discovered and cataloged by Charles Messier on March 18, 1781 when he also cataloged 7 more nebulous objects in the same region of the sky, all member galaxies of the Virgo Cluster, and in addition, globular cluster M92.
This bright giant galaxy is either an elliptical of type E3 or a lenticular galaxy of type S0_1(3); modern classifications apparently tend more to the lenticular classification, NED gives both classes.

This bright giant galaxy is either an elliptical of type E3 or a lenticular galaxy of type S0_1(3); modern classifications apparently tend more to the lenticular classification.
M86 is the galaxy which has the fastest approaching velocity, and thus the highest blue shift, of all Messier galaxies (and thus all Messier objects): It is approaching us at 419 km/sec !
But this is not totally uncommon in huge clusters of galaxies as the Virgo cluster, because due to its enormous mass, this huge agglomeration of mass has a strong gravitational field.

Like spiral galaxies, they contain a disk, but like elliptical galaxies, they are usually short on dust, gas, and pretty spiral arms.
Lenticulars are relatively little studied, possibly because of their seemingly benign nature.
The image was taken to help determine how lenticular galaxies formed, and what happens in their centers.

Irregular galaxies, which account for about 5 percent of the galaxies we observe nearby, are forming, colliding, dynamically disturbed systems that do not fit in any of the other three categories.
Lenticulars are denoted S0 (or SB0, with a bar), and subdivided to classes 1, 2, and 3, based on dust absorption within their disks.
Among the 22 galaxies we have 16 spirals (M58, M61, M63, M65, M81, M88, M90, M91, M95, M96, M98, M99, M100, M104, M106 and M108), 4 ellipticals (M49, M59, M87 and M105), and 2 lenticulars (M84 and M86).

 Galaxy M86   (Site not responding. Last check: 2007-10-14)
M86 is in the center of the Virgo Cluster of galaxies.
Although the Virgo Cluster is moving away from Earth at about 1,100 km/sec, M86 is fastest Messier odject approaching Earth with velocity of 419 km/sec and thus the highest blue shift of Messier galaxies.
The fastest moving Virgo Cluster galaxy is NGC 4388 at 2535 km/sec and is receding Earth with a red shift volocity of 1,400 km/sec.

 Galaxy classification - Wikipedia, the free encyclopedia
Astronomers classify galaxies based on their overall shape (elliptical, spiral or barred spiral) and further by the specific properties of the individual galaxy (for example degree of ellipse, number of spirals or definition of bar).
From this, astronomers have constructed a theory of galaxy evolution which suggests that ellipticals are, in fact, the result of collisions between spiral and/or irregular galaxies, which strip out much of the gas and dust and randomize the orbits of the stars.

 Gas and Galaxy Evolution: Abstracts
Galaxies in the core region are expected to have a different merger history than the galaxies populating the outskirts.
The scientific applications of such a survey are numerous: studies of the systematics of rotation curves (and hence dark matter content) of galaxies as a function of galaxy type and luminosity, studies of the HI morphologies as a function of galaxy type and luminosity, studies of the stability of warps in the HI disks.
Early-type galaxies are generally considered to be gas poor, but it has become clear in the past few years that many galaxies of this type do have an ISM that is similar to that in spirals, the main difference being that they have less of it.

The Virgo cluster membership of M86 is also suggested by its more or less obvious interaction with the intergalactic gaseous matter in the Virgo cluster, which was reported from X-ray observations, discovered by Forman et.al.
This, however, is probably a perspectivic effect, as otherwise their outlayers would be even much more distorted; there is probably some radial distance, or distance difference from us, between these two galaxies; it is not known which one is a bit closer to, and which a bit farther away from us.
On M86's fast motion through the intergalactic medium of the Virgo Cluster (the "Intra-Cluster Matter", ICM), the galaxy's interstellar matter collides at high velocity with this material, and is probably "ram-pressure stripped" from the galaxy (Rangarajan et.al.

 Messier 86 - Wikipedia, the free encyclopedia
M86 (also known as Messier Object 86, Messier 86 or NGC 4406) is a lenticular galaxy in the constellation Virgo.
M86 lies in the heart of the Virgo Cluster of galaxies and forms a most conspicuous group with another giant, Lenticular Galaxy M84.
It displays the highest blue shift of all Messier objects, as it is approaching the Milky Way at 419 km/s.

They clearly exhibit a bulge and disk similar to spiral galaxies, but do not show any signs of spiral arms or significant quantities of interstellar material.
They consist primarily of old, population II stars and for this reason, are often misclassified as elliptical galaxies when viewed face-on.
The origins of S0 galaxies are still unknown, but one idea is that they were originally spiral galaxies which either lost or used up their interstellar material through interactions with another galaxy.

 Messier Object 86
This group may be viewed in one field even at medium power, so that it is often photographed and we have more images including M84 and M86.
Deep images of this group have revealed that these galaxies are actually much larger than indicated in conventional images, as the one in this page.
In addition, we have images of the whole central part of the Virgo Cluster: M87 together with Markarian's chain around M84 and M86.

 Galaxies M84 and M86
M86 and M84 are two giant lenticular galaxies at the heart of the Virgo cluster of Galaxies.
Located in Markarian's Chain, M84 was studied by the Hubble Space Telescope in 1997 and was found to contain a massive central object, estimated at 300 million solar masses, located less than 26 light years from the center of the galaxy.
NGC 4438, a spiral galaxy at the left of the photo, appears to be distorted by an interaction with nearby NGC 4435.

 Messier Object 86   (Site not responding. Last check: 2007-10-14)
This bright giant galaxy is either an elliptical of type E3 or a lenticular galaxy of type S0_1(3).
However, the present author thinks it is just this high approach velocity which indicates that M86 is most probably a true cluster member, although this would indicate that it is moving at a peculiar velocity of more than 1500 km/sec, by chance in a direction pointing toward us.
But this is not totally uncommon in huge clusters of galaxies as the Virgo cluster, because in the strong gravitational field of this huge agglomeration could easily accelerate it to the high velocity observed; it would be much more difficult to find an explanation for such a high velocity for a field galaxy !
