The Markarian's Chain region of the Virgo supercluster contains 3 giant elliptical galaxies (M84, M86, M87) and dozens of smaller spiral, elliptical and irregular galaxies. These stellar cities - containing from billions to several trillion stars each lie at a distance of around 60 million light years from us. Our own Milky Way and its Local Group are merely a small suburb on the outskirts of The Virgo supercluster, which contains upward of 1,000 individual galaxies. Dark matter causes the galaxies to form gravitationally bound chains, one of which can be seen in the image.
