Hubble has transformed our view of the universe in its 26 years of life.
The space telescope has helped scientists figure out the age of the universe, found new moons of Pluto, peered more deeply into the cosmos than ever before and led to even more discoveries.
The telescope has also produced some of the most beautiful and scientifically fruitful images ever taken of objects in our galaxy and beyond. The deep field survey revealed thousands of galaxies that have never been seen before, and Hubble's "Pillars of Creation" is arguably the most iconic deep space photo ever taken.
And the telescope isn't done with its work. Scientists think that Hubble could function into the 2020s, even after its successor, the James Webb Space Telescope is expected to come online in 2018
