Happy Friday

This is the galaxy cluster Heic 1217, hidden in the above photograph are three tiny specks of red representing the most distant and youngest galaxy ever seen.  This galaxy cluster is dense enough to act as a gravitational lens, bending and magnifying the galaxies behind it.  Hubble and the Spitzer space telescope found three separte images of the same galaxy named MACS J0647.7+7015.  We see this tiny galaxy only 420 million years after the big bang.
