Hubble Space Telescope

The Hubble Space Telescope is a large space-based observatory orbiting Earth, launched in 1990 by NASA and the European Space Agency. Named after astronomer Edwin Hubble, it observes the Universe across visible light, ultraviolet, and near-infrared wavelengths, peering deeper into galactic history than ground-based instruments can reach.

Hubble revolutionized astronomy by escaping atmospheric distortion. Early images revealed the cosmic distance ladder, refined estimates of the Universe's age, and captured the deepest fields ever seen—revealing thousands of distant galaxies in tiny patches of sky. Its discoveries about Dark Energy and Dark Matter reshaped our understanding of cosmic expansion itself.

The telescope required an in-orbit repair mission in 1993 to correct its primary mirror flaw, demonstrating human ingenuity and the power of redundant design. Multiple servicing missions have upgraded its instruments, extending its scientific lifespan far beyond original expectations.

Though aging, Hubble continues producing transformative science alongside newer observatories like the James Webb Space Telescope. Its legacy proves that Expertise and persistence can unlock the Universe's deepest secrets.
