    Astronomers are always searching for evidence on the formation of the universe. Using both the Hubble and Spitzer space telescopes, astronomers found and measured a tiny galaxy that appears to have formed 500 years after the formation of the universe. This makes this small object a new record holder. Without the help of a gravitational lens that magnifies the light from the distant object, the telescopes would never have detected the faint object.
