Hubble Space Telescope (HST)
Named in honor of the trailblazing astronomer Edwin Hubble, the Hubble Space Telescope is a large, space-based observatory that has changed our understanding of the cosmos since its launch and deployment by the space shuttle Discovery in 1990. The Hubble Space Telescope marked the beginning of a new era in humanity’s exploration of the universe. From above Earth’s obscuring atmosphere, Hubble can obtain extremely high-resolution images and detailed spectroscopic data of the cosmos, from our solar system to the distant, early universe. Scientists submit proposals to use Hubble through an open, peer-reviewed, anonymous competition.
Hubble’s capabilities have grown immensely in its over 30 years of operation. This is because new, cutting-edge scientific instruments have been added to the telescope over the course of five astronaut servicing missions. By replacing and upgrading aging parts, these servicing missions have greatly extended the telescope’s lifetime.
Through the middle of the next decade, HST will remain the only space-based telescope providing spectroscopy and high-resolution imaging at ultraviolet, visible, and near-infrared wavelengths. Since the James Webb Space Telescope launched in 2021, the two observatories have been working in tandem to push astronomy forward and pursue the boldest scientific questions of our time.
