A Revolutionary Telescope

Hubble became a household word by expanding our knowledge of the cosmos and for its spectacular images. But the telescope also impacted our technologies, industries, and culture.

Quick Facts

Hubble detector technology has been used to monitor the preservation of America’s most sacred documents - the Declaration of Independence and the Constitution.

A letter "R" on a historic document is shown in pink outlined in blue, as a result of false-color imaging. The R is speckled with blue. The background of the document is primarily yellow, with swaths of green and blue.

Scientists from 45 countries have submitted proposals to make observations on Hubble.

The furthest object observed by Hubble is galaxy GN-z11, whose light took 13.4 billion years to reach us.

Over 21,000 peer-reviewed science papers have been published on Hubble's discoveries. Those papers have been cited in other science papers over a million times.

Science Impacts

Seeing more, seeing farther, seeing deeper

Hubble's view from orbit unleashed a flood of cosmic discoveries that changed astronomy forever. From its explorations of dark matter to its quest to determine the age of the universe, Hubble has helped answer some of the most compelling astronomical questions of our time.

Field is filled with galaxies in colors of white, yellow, blue-white, and red; all on a black background.

Hubble's launch and deployment in April 1990 marked the most significant advance in astronomy since Galileo's telescope. Thanks to five servicing missions and more than 30 years of operation, our view of the universe and our place within it has never been the same. Deep fields, including the Hubble Ultra Deep Field 2014 seen here, are examples of Hubble images that have had profound impact on our understanding of the cosmos.

Hubble Captures a Bright Galactic and Stellar Duo

A spiral galaxy, seen face-on to the viewer. The bright center of the galaxy is crossed by a glowing bar, and it is surrounded by tightly wound spiral arms, forming a circular shape with relatively clear edges. Faraway galaxies are visible around it, along with a few bright stars, on a dark background. One star to the right of the galaxy is very large and extremely bright with long diffraction spikes.

Hubble Goes Hunting for Small Main Belt Asteroids

This is a Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape made up of bright blue stars wound around a yellow-white hub of central stars. The hub has a slash of stars across it, called a bar. The galaxy is tilted face-on to our view from Earth. A slightly s-shaped white line across the top is a Hubble image is of an asteroid streaking across Hubble's view. It looks dashed because the image is a combination of several exposures of the asteroid flying by like a race car.

Hubble Spots a Galaxy Hidden in a Dark Cloud

A spiral galaxy seen nearly face-on. The disk holds many tightly wound spiral arms. They contain small strands of reddish dust, near the center. On the left side, the disk features glowing patches of star formation. The whole right side, and part of the center, is obscured by a large cloud of dark grey gas which crosses the image.

Top of the image holds the phrase, "Hubble Focus." The "o" in focus is Hubble as we look down the tube of the telescope.

Cultural Impact

Putting the stars in “starstruck”

Hubble and its images have become a part of our cultural landscape, appearing in film, music, art and much more. From tattoos to television and shirts to stamps, Hubble is woven into the fabric of daily life.

Hubble images are mounted on the wall over sculptures and between classical pillars at the Walters Art Musuem.

"Mapping the Cosmos: Images from the Hubble Space Telescope," brings together over 20 Hubble images as part of the Walters Art Museum exhibit "Maps: Finding Our Place in the World." The exhibit was created through a unique collaboration between the Walters, scientists and experts at the Space Telescope Science Institute (STScI), and Professor Elizabeth Rodini and her students in the "Behind the Scenes at the Walters Art Museum" class at Johns Hopkins University.

Technology Benefits

From capturing visions of space to improving life on the ground

Scientists and engineers have created a wealth of new technology for Hubble, both while it was being built and to further its mission. Many of these advances found applications on Earth.

Chris' skates were sharpened with a tool that was inspired by mirror-polishing techniques used to produce high-quality optics for Hubble and other NASA observatories. Innovations made to improve Hubble's vision and longevity often made their way into earthly technology.
