It's a cluster of galaxies about 200 million light years in diameter. The Milky way is in the cluster. Check out some pictures at the link below.

Virgo Supercluster

The Virgo Supercluster or Local Supercluster is the galactic supercluster that contains the Local Group, the latter which, in its turn, contains the Milky Way and Andromeda galaxies.

Disk and halo

The Supercluster consists of two components: disk component and halo component. The flattened disk component has a pancake-like shape, and contains 60% of the Virgo Supercluster's luminous galaxies. The halo component consists of many elongated objects, and contains 40% of the Virgo Supercluster's luminous galaxies.

Diameter

The diameter of the Supercluster is about 200 million light years; it contains about 100 groups and clusters of galaxies and is dominated by the Virgo cluster near its center. Our Local Group is located near the edge and is being drawn inward toward the Virgo cluster.

Divisions

The Virgo Supercluster is subdivided into groups of clusters called galaxy clouds. Three clouds are on the disk component: Virgo cluster, Canes Venaciti Cloud and Virgo II Cloud. The halo consists of many elongated clouds pointing toward the Virgo Cluster.

The Virgo Cluster is a cluster of galaxies at a distance of approximately 59 ± 4 Mly (18.0 ± 1.2 Mpc)[2] away in the constellation Virgo. Comprising approximately 1300 (and possibly up to 2000) member galaxies, the cluster forms the heart of the larger Local Supercluster, of which the Local Group is an outlying member. It is estimated that its mass is 1.2×1015 M☉ out to 8 degrees of the cluster's center or a radius of about 2.2 Mpc.[2]

Many of the brighter galaxies in this cluster, including the giant elliptical galaxy Messier 87, were discovered in the late 1770s and early 1780s and subsequently included in Charles Messier's catalogue of non-cometary fuzzy objects. Described by Messier as nebulae without stars, their true nature was not recognized until the 1920s.

The cluster subtends a maximum arc of approximately 8 degrees centered in the constellation Virgo. Many of the member galaxies of the cluster are visible with a small telescope.

The cluster is a fairly heterogeneous mixture of spirals and ellipticals. As of 2004, it is believed that the spirals of the cluster are distributed in an oblong prolate filament, approximately 4 times as long as wide, stretching along the line of sight from the Milky Way.[3] The elliptical galaxies are more centrally concentrated than the spiral galaxies.

The cluster is an aggregrate of at least three separate subclumps centered on the galaxies M87, M86, and M49. Of the three subclumps, the one centered on M87 is the dominant one, with a mass of approximately 1014 solar masses, which is approximately an order of magnitude larger than the other two subclumps. [4]

The large mass of the cluster is indicated by the high peculiar velocities of many of its galaxies, sometimes as high as 1,600 km/s with respect to the cluster's center.

The Virgo cluster lies within the Local Supercluster, and its gravitational effects slow down the nearby galaxies. The large mass of the cluster has the effect of slowing down the recession of the Local Group from the cluster by approximately ten percent.

*sigh*
http://en.wikipedia.org/wiki/Virgo_Supercluster
wikipedia strikes again.

I think wikipedia should get honorable mention and a level 7 status here since it has like 80% of the answers to these questions.
