PHOTOS: Hubble's Sexiest Spiral Galaxies
Most globular clusters are quite old. Initial estimates of IC 4499 from the 1990s suggested this bunch of stars was surprisingly young. But follow-up observations with Hubble have shown that IC 4499, like most of the galaxy's globular clusters, is about 12 billion years old, according to NASA. That's quite ancient, considering the universe got its start approximately 13.8 billion years ago. For comparison, Earth's sun was born about 4.6 billion years ago.
The Hubble Space Telescope launched in 1990, and for more than two decades, the telescope has beamed back amazing images of the cosmos from its perch high above the clouds, free of the distortion of Earth's atmosphere.
