THE HUBBLE ULTRA-DEEP FIELD AS SEEN FROM EARTH


 
A note for people who may not know, almost every speck of light (~3,000) in that original deep field photo is a galaxy. Each galaxy containing between 10 million and 100 trillion stars.

Using a very conservative average of 1 trillion stars per galaxy - that one small square of the nights sky has 1 quadrillion (1015) stars in it.
