Introduction
HST is a space-based great observatory that observes at ultraviolet through near infrared wavelengths. High resolution imaging and wide-ranging spectroscopic capabilities enable forefront research across all domains of astrophysics. Time on HST is awarded through an open peer-reviewed competition.
The Hubble Space Telescope's launch in 1990 sped humanity to one of its greatest advances in that journey. Hubble is a telescope that orbits Earth. Its position above the atmosphere gives it a view of the universe that typically far surpasses that of ground-based telescopes.
Thirty-three years since launch, the Hubble Space Telescope continues its role at the forefront of astronomy, ranging from our own Solar System to the high-redshift universe.
Through the middle of the next decade, HST will remain the only space-based telescope providing spectroscopy and high-resolution imaging at UV, optical, and near-infrared wavelengths. With the launch of JWST in 2021, the bold science questions pursued with HST will be bolstered by the complementary capabilities of the two observatories.
