Public Invited Into Hubble’s Vast Science Archive to Dig Out The Best Unseen Hubble Images

For Your Information:


Over two decades in orbit, the Hubble Space Telescope has made a huge number of observations. Every week, we publish new images on the ESA/Hubble website.

But hidden in Hubble’s huge data archives are still some truly breathtaking images that have never been seen in public. We call them Hubble’s Hidden Treasures — and we’re looking for your help to bring them to light.



We’re inviting the public into Hubble’s vast science archive to dig out the best unseen Hubble images. Find a great dataset in the Hubble Legacy Archive (, adjust the contrast and colours using the simple online tools and submit to our Hubble’s Hidden Treasures Contest Flickr group (, and you could win an iPod Touch in our Hubble’s Hidden Treasures Competition.

For an extra challenge, why not try using the same software that the professionals use to turn the Hubble data into breath-taking images? Download the data from the Hubble Legacy Archive (, process using powerful
open-source software such as the ESO/ESA/NASA FITS Liberator ( and make a beautiful image for our Hubble’s Hidden Treasures Image Processing Contest Flickr group ( And you’ll be in with a chance to win an iPad.

Rules and further information are available on the page:

NASA/ESA and Hubble Give Us The Glittering Jewels of Messier 9


The NASA/ESA Hubble Space Telescope has produced the most detailed image so far of Messier 9, a globular star cluster located close to the centre of the galaxy. This ball of stars is too faint to see with the naked eye, yet Hubble can see over 250 000 individual stars shining in it.

Hubble Reveals a New Class of Extrasolar Planet

Observations by the NASA/ESA Hubble Space Telescope have come up with a new class of planet, a waterworld enshrouded by a thick, steamy atmosphere. It’s smaller than Uranus but larger than Earth.

Hubble Pinpoints Furthest Protocluster of Galaxies Ever Seen

Using the NASA/ESA Hubble Space Telescope, astronomers have uncovered a cluster of galaxies in the initial stages of development, making it the most distant such grouping ever observed in the early Universe.

Hubble Uncovers Tiny Galaxies Bursting with Starbirth in Early Universe

Using its infrared vision to peer nine billion years back in time, the NASA/ESA Hubble Space Telescope has uncovered an extraordinary population of tiny, young galaxies that are brimming with star formation.

Hubble Survey Carries Out a Dark Matter Census

The NASA/ESA Hubble Space Telescope has been used to make an image of galaxy cluster MACS J1206.2-0847. The apparently distorted shapes of distant galaxies in the background is caused by an invisible substance called dark matter, whose gravity bends and distorts their light rays. MACS 1206 has been observed as part of a new survey of galaxy clusters using Hubble.

Huge Glowing Bubbles of Gas, Captured in this image from the NASA/ESA Hubble Space Telescope


Hubble’s famous images of galaxies typically show elegant spirals or soft-edged ellipses. But these neat forms are only representative of large galaxies. Smaller galaxies like the dwarf irregular galaxy Holmberg II come in many shapes and types that are harder to classify. This galaxy’s indistinct shape is punctuated by huge glowing bubbles of gas, captured in this image from the NASA/ESA Hubble Space Telescope.

Four Unusual Views of the Andromeda Galaxy

The Andromeda Galaxy is revealed in unprecedented detail in four archive observations from the NASA/ESA Hubble Space Telescope. They show stars and structure in the galaxy’s disc, the halo of stars that surrounds it, and a stream of stars left by a companion galaxy as it was torn apart and pulled in by the galaxy’s gravitational forces.


Hubble Space Telescope has made its Millionth Observation

The NASA/ESA Hubble Space Telescope has made its millionth observation
since its launch 21 years ago. The telescope was used to search for the
chemical signature of water in the atmosphere of planet HAT-P-7b, a gas
giant larger than Jupiter which orbits the star HAT-P-7.

Scientists Get Into Crash Investigation On A Galactic Scale

A team of scientists has studied the galaxy cluster Abell 2744, nicknamed Pandora’s Cluster. They have pieced together the cluster’s complex and violent history using telescopes in space and on the ground, including ESO’s Very Large Telescope and the Hubble Space Telescope. Abell 2744 seems to be the result of a simultaneous pile-up of at least four separate galaxy clusters and this complex collision has produced strange effects that have never been seen together before.
