Hubble telescope celebrates 34th anniversary with an iridescent Dumbbell Nebula (image)

To write that the Hubble Space Telescope is legendary would be an understatement.

In the 34 years this telescope has been in orbit, it has produced breathtaking images of the cosmos. One that sticks out, for instance, is the iconic Hubble Ultra-Deep Field, aka the deepest visible-light view of our universe ever created. Thanks to the Hubble telescope, astronomers know our universe is about 13.7 billion years old and that many galaxies host supermassive black holes at their centers. It’s because of this spaceborne eye on the cosmos that scientists were also able to map the mysterious substance dark matter in 3D.

“Most of Hubble’s discoveries were not anticipated before launch,” NASA’s Hubble mission team said in a statement. “The space telescope is the most scientifically productive space astrophysics mission in NASA history. The demand for using Hubble is so high it is currently oversubscribed by a factor of six-to-one.”
