NASA's Hubble Space Telescope is one of the most powerful scientific
instruments ever conceived. Hubble’s most important discoveries
have provided answers to questions that astronomers did not yet know
how to ask, and found objects that were not yet imagined. This

Hubble far exceeds its original science goals and unveiled an even
more complex and mysterious universe than once envisioned.
