The first optical map of this region was produced by the Las Campanas survey headed by Sandage, which measured the apparent velocities of about 1300 of this region's currently known 2000 objects.

Due to the appearance the plot of its constituent objects in redshift space, this region's main body is sometimes called the "finger of God." This region's center contains a string of galaxies called Markarian's chain and this region's low-velocity tail contains the most blueshifted galaxies known around the M86 galaxy. The galaxy M87 lies at the heart of this region, into which the Milky Way, and the rest of the Local Group, is falling at a rate of about 250 km/s. This region is at the center of a supercluster with which it shares its name, and which is sometimes called the Local Supercluster. For 10 points, identify this closest major cluster of galaxies to the Milky Way, which lies in the constellation whose alpha star is Spica.
