The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy.

Hubble performs in response to detailed instructions from people on the ground. The antennas allow technicians to communicate with the telescope, telling it what to do and when to do it. Four antennas receive and send information to a set of satellites, which in turn communicate with Earth.
Hubble is powered by sunlight. Each wing-like array has solar cells that convert the Sun’s energy into electricity. Some of that electricity runs the telescope, some is stored in onboard batteries for the periods when Hubble is in Earth’s shadow.
Several computers and microprocessors reside in Hubble’s body and in each science instrument. There are two main computers. One talks to the instruments, sends commands and other information, and transmits data; the other handles pointing control, gyroscopes and other system-wide functions.
Hubble has blanket of multilayered insulation, which protects the telescope from temperature extremes.
Hubble uses a combination of gyroscopes, reaction wheels and Fine Guidance Sensors to orient itself.
Learn about the Hubble Space Telescope, a Cassegrain reflector telescope that orbits above the Earth and observes the universe in visible, near-infrared and ultraviolet light. Discover its history, instruments, discoveries and how to propose for time on the telescope.

The giant planet Jupiter, in all its banded glory, is revisited by the NASA/ESA Hubble Space Telescope in these latest images, taken on 5–6 January 2024, that capture both sides of the planet. Hubble monitors Jupiter and the other outer Solar System planets every year under the Outer Planet Atmospheres Legacy programme (OPAL).
May 19, 2022 · Hubble Space Telescope has calibrated more than 40 cosmic distance markers to help scientists precisely measure the expansion rate of the universe. The results reveal a discrepancy between the local and early universe expansion rates, and suggest new physics beyond dark energy.
