Hubble Space Telescope
Introduction to the Hubble Space Telescope
The Hubble Space Telescope (HST) is a space-based observatory orbiting Earth. Hubble observes the universe in multiple wavelengths of light, from ultraviolet to visible to near-infrared.
The Hubble Space Telescope’s launch in 1990 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.
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.

NASA’s Hubble Sees White Dwarf Eating Piece of Pluto-Like Object
September 18, 2025An illustration showing a glowing white object in the upper left corner. This object is encircled by hundreds of thin, concentric, pale-yellow rings on an angle from bottom left to top right. The rings are palest closest to the central, glowing white object. A curving trail of gray, rock-like fragments marches across the right side, through the thin rings and joins the rings at far right. Several large fragments of varying sizes appear in the foreground. These objects have white, comet-like tails streaking away from the glowing white object in the rings’ center. The curving trail of fragments bends toward the glowing white object. At the bottom left corner is the label Artist’s Concept. -
NASA's Hubble Uncovers Rare White Dwarf Merger Remnant
August 13, 2025An illustration of a white dwarf star merging with a red giant star. The red giant is an arch across the bottom of the illustration, with a textured surface. The white dwarf is a white pinpoint object at upper center right. The white dwarf in embedded inside a teardrop-shaped cocoon of white gas. It is enveloped in a white open ellipsoid that is the bow shock from speeding through the red giant’s outer atmosphere. The words "artist’s concept" are at lower left. -
As NASA Missions Study Interstellar Comet, Hubble Makes Size Estimate
August 07, 2025At the center of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the comet’s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. Several short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.
