Hubble Spies a Cosmic Eye

An oval-shaped spiral galaxy. Its core is a compact, glowing blue spot. A bright bar of light, lined with dark reddish dust, extends horizontally to the edge of the disk. A spiral arm emerges from each end of the bar and follows the edge of the disk, lined with blue and red glowing patches of stars, to the opposite end and a little off the galaxy. A scattering of blue stars are between us and the galaxy.

Hubble Images a Grand Spiral

A close-up of a spiral galaxy, seen face-on. Its center is a bright white point, surrounded by a large yellowish oval with thin lines of dust swirling in it. From the sides of the oval emerge two bright spiral arms which wind through the round disk of the galaxy, filled with shining pink spots where stars are forming and more dark reddish dust. Many stars are visible in the foreground, over and around the galaxy.

NASA’s Hubble Celebrates Decade of Tracking Outer Planets

A montage of Hubble Space Telescope images of our solar system's four giant outer planets: Jupiter, Saturn, Uranus, and Neptune, taken under the OPAL (Outer Planet Atmospheres Legacy) program over 10 years, from 2014 to 2024.

A spiral galaxy filling the view. Its disk holds many bright red spots where stars are forming, dark reddish threads of dust that obscure light, and bluish glowing areas that hold concentrations of older stars. It has a large, glowing yellow oval area at the center, from which two spiral arms wind through the galaxy’s disk. One side of the disk appears rounded (bottom of the image) while the opposite side appears somewhat squared-off (top of the image).

A Hubble Space Telescope Imaging Spectrograph (STIS) coronagraph image of quasar 3C 273. It looks the same as the WFPC2 image, but in shades of blue. A black circle (labeled “core light blocked”) blocks the glare of the quasar. Blue-colored filamentary material is visible near the black hole. The extragalactic jet is still visible.

NASA’s Hubble Takes the Closest-Ever Look at a Quasar

Article2 weeks ago

A spiral galaxy seen directly from the side, such that its disk looks like a narrow diagonal band across the image. A band of dark dust covers the disk in the center most of the way out to the ends, and the disk glows around that. In the center of the galaxy, a whitish circle of light bulges out above and below the disk. Each end of the disk curves slightly. The background is black and mostly empty.

Artist's concept of early stages of the young star FU Orionis outburst. The star, a bright yellow sphere near the center, and its fluffy disk of gas and dust are slightly tilted, extending from the top left corner to the bottom right. The swirling disk is bright yellow close to the star and gradually transitions to dark orange moving toward the edges of the frame. The top left and right corners reveal a black, starless background.

Mosaic of the Pillars of Creation visualization model, composed of 4 rectangular strips oriented 45 degrees clockwise from vertical. Strips alternate between Hubble and Webb views of the visualization model, with each strip labeled: “Hubble” at lower right corners of first and third strips; “Webb” at upper left corners of the second and fourth strips. Webb strips have drop shadows that make it look like they are overlaid on top of larger Hubble image. Mosaic shows 3 vertical structures (pillars) of thick smoke-like material. Pillar edges are glowing, with thin wisps of material moving away into space. In Hubble strips, pillars are dark brown and opaque, on greenish blue background. In Webb strips, pillars are bright orange to brown with a distinct area of bright red at the top of middle pillar. A red star appears at the tip of a peak in the left pillar and the background is deep blue.

A New View of the Universe

How did a telescope become a household name and change how we look at the cosmos forever?

With over 1.5 million observations and 20,000+ papers published on its discoveries, Hubble is the most productive science mission in the history of NASA. Yet the story of Hubble’s success starts before NASA even existed. It includes adversity, human ingenuity, heroic spacewalks, risk taking, and discovery. Learn the background of one NASA’s most famous missions.

Astronauts aboard Space Shuttle Atlantis snapped a still photo of the Hubble Space Telescope after it was grappled by the shuttle's Canadian-built Remote Manipulator System during Servicing Mission 4. The mission left the telescope at the peak of its scientific capabilities, allowing it to continue furthering our knowledge of the cosmos.

Science, Technology, Culture: Hubble's Growing Legacy

From cultural touchstone to technological influencer, Hubble has left its mark on Earth

Hubble science has rewritten astronomy textbooks as its discoveries continually provide deeper explanations of astronomical objects and unveil new phenomena. But science isn’t the only way Hubble has impacted our world. From image detectors that are now used in the fight against breast cancer to science images that are used in Hollywood blockbuster movies, Hubble is embedded in our everyday lives and pop culture.

The Hubble Telescope in space gripped by the space shuttle's robotic arm.

Held by the space shuttle Discovery’s robotic arm, Hubble is unfurling its solar arrays as it hovers over Earth during its deployment in April 1990. The technology in Hubble and in its ground system has been used for numerous other benefits down here on Earth.

Discovering the Unimagined

Hubble has not only furthered our knowledge of the known universe, it's shocked the astronomical world with never-before-seen phenomena.

When Hubble was launched, no planets around other stars had been discovered, Pluto had only one known moon, and dark energy was not even a concept. With over three decades of observations, Hubble has changed humanity’s understanding of the universe. We now know that black holes exist at the center of almost all galaxies, Jupiter’s massive storm – the Great Red spot – is now shrinking, light can echo just like sound, and the universe is expanding at an accelerating rate. Learn about Hubble’s great discoveries, understand the basics behind Hubble’s scientific capabilities, and explore its incredible images of the cosmos.

a packed field of galaxies and curved blue streaks

Abell 370 is a massive galaxy cluster whose immense gravity distorts and magnifies the light of galaxies behind it. Hubble has used it to push its vision beyond its usual capabilities and see even farther galaxies. Such capabilities have allowed Hubble to change our understanding of all aspects of astronomy.

An Observatory for the Ages

Even after three decades in the harsh environment of space, Hubble is still at the peak of its scientific capability

Designed and built in the 1970’s and 1980’s, Hubble has far surpassed its 15-year life expectancy and produced science never thought possible at the time of its launch. Learn about Hubble’s unique design, the human spaceflight missions that have extended its life, and the ground operations that keep it as productive as ever.
