One of NASA's grandest achievements, Hubble
has peered into the far recesses of the universe and provided humbling glimpses of stars at the moments of their birth and death.

According to scientists, the most recent discovery made by Hubble
showed that the galaxy, known as UDFj-39546284, likely existed when the universe was just 380 million years old.
For 21 years Hubble
has been the premier space science observatory, astounding us with deeply beautiful imagery and enabling ground-breaking science across a wide spectrum of astronomical disciplines," said NASA Administrator Charles Bolden.
Though the universe is filled with billions upon billions of stars, Hubble
Space Telescope has been trained on a single variable star that in 1923 altered the course of modern astronomy.
