NASA's space sciences chief Ed Weiler says the actual photos fulfill the last of the major goals that NASA had for the Hubble telescope before it launched in 1990.
Ed Weiler, Chief of NASA's Space Sciences, said, "This is an 18 and a half year dream come true."
The planet discovered by Hubble, Fomalhaut b, is one of the smallest exoplanets found yet. It's only about 200 million years old, a baby compared to the more than 4 billion-year-old planets in our solar system.
That's important to astronomers because they can study what Earth and planets in our solar system may have been like in their infancy.
