Now that you know how many galaxies are in our expanding Universe, you might be wondering about their speeds.

This hypnotic galaxy is responsible for giving birth to a million stars in the universe! The gracefully curving arms of the majestic spiral galaxy, which is called "M51", look like a huge spiral staircase leading you to the very heart of space.
"The lessons of science should be experimental also. The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow outvalues all theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry." -Ralph Waldo Emerson
"The cave you fear to enter holds the treasure you seek." -Joseph Campbell
Space, as you know, is mostly empty, as the typical distance between galaxies far exceeds the size of the galaxies themselves.
But in a few select regions of the Universe, where the mass density is unusually above average, galaxies cluster together by the thousands. The closest huge cluster to us like this is the Coma Cluster, containing more galaxies than 95% of all known galaxy clusters.
