"A Look to the Heavens"

"Almost every object in the below photograph is a galaxy. The Coma Cluster of Galaxies pictured here is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies houses billions of stars - just as our own clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us.
In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other! Most galaxies in Coma and other clusters are ellipticals, while most galaxies outside of clusters are spirals. The nature of Coma's X-ray emission is still being investigated."

"A philosopher once asked, "Are we human because we gaze at the stars, or do we gaze at them
because we are human?" Pointless, really... ”Do the stars gaze back?" Now that's a question..."
