One of the top discoveries from Hubble include the age of the universe. From 1996 and 1997 images, the distance from Earth to galaxy NGC 4603 was determined to be 108 million light years. Extrapolating backward theorizes that the Big Bang happened between 9 and 14 billion years ago. In recent years the Hubble has helped make even more precise measurements.

1997 images from Hubble showed that three different galaxies contained black holes helping scientists to theorize that nearly all galaxies contained black holes.Credit: Karl Gebhardt (University of Michigan), Tod Lauer (NOAO), and NASA
