NASA's Starry-Eyed Hubble Telescope Celebrates 20 Years of Discovery.Hubble Space Telescope Hubble Space Telescope (HST), the first large optical orbiting observatory. Built from 1978 to 1990 at a cost of $1.5 billion, the HST (named for astronomer E. P. Hubble) was expected to provide the clearest view yet obtained of the universe. achieves the major milestone of two decades on orbit, NASA NASA: see National Aeronautics and Space Administration.

Independent U.S. and the Space Telescope Science Institute The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST; in orbit since 1990) and for the James Webb Space Telescope (JWST; scheduled to be launched in 2013). , or STScI, in Baltimore are celebrating Hubble's journey of exploration with a stunning new picture and several online educational activities. There are also opportunities for people to explore galaxies as armchair scientists and send personal greetings to Hubble for posterity.
NASA is releasing a new Hubble photo of a small portion of one of the largest known star-birth regions in the galaxy, the Carina Nebula. Three light-year-tall towers of cool hydrogen laced with dust rise from the wall of the nebula. The scene is reminiscent of Hubble's classic "Pillars of Creation Pillars of Creation can refer to:
- The Pillars of Creation, a fantasy novel by Terry Goodkind
- Columns of interstellar gas and dust in the Eagle Nebula

NASA's best-recognized, longest-lived and most prolific space observatory was launched April 24, 1990, aboard the space shuttle Discovery during the STS-31 mission. Hubble discoveries revolutionized nearly all areas of current astronomical research from planetary science to cosmology.
Over the years, Hubble has suffered broken equipment, a bleary-eyed primary mirror, and the cancellation of a planned shuttle servicing mission. But the ingenuity and dedication of Hubble scientists, engineers and NASA astronauts allowed the observatory to rebound and thrive. The telescope's crisp vision continues to challenge scientists and the public with new discoveries and evocative images.
"Hubble is undoubtedly one of the most recognized and successful scientific projects in history," said Ed Weiler, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "Last year's space shuttle servicing mission left the observatory operating at peak capacity, giving it a new beginning for scientific achievements that impact our society."
Hubble fans worldwide are being invited to take an interactive journey with Hubble by visiting http://www.nasa.gov/externalflash/Hubble20/. They can also visit http://www.hubblesite.org to share the ways the telescope has affected them. Follow the "Messages to Hubble" link to send an e-mail, post a Facebook message, or send a cell phone text message. Fan messages will be stored in the Hubble data archive along with the telescope's science data. For those who use Twitter, you can follow @HubbleTelescope or post tweets using the Twitter hashtag #hst20.
The public also will have an opportunity to become at-home scientists by helping astronomers sort out the thousands of galaxies seen in a Hubble deep field The Hubble Deep Field (HDF) is an image of a small region in the constellation Ursa Major, based on the results of a series of observations by the Hubble Space Telescope. It covers an area 144 arcseconds across, equivalent in angular size to a tennis ball at a distance of 100 observation. STScI is partnering with the Galaxy Zoo consortium of scientists to launch an Internet-based astronomy project where amateur astronomers can peruse and sort galaxies from Hubble's deepest view of the universe into their classic shapes: spiral, elliptical el·lip·tic or el·lip·ti·cal
1. Of, relating to, or having the shape of an ellipse.
2. Containing or characterized by ellipsis.
a. , and irregular. Dividing the galaxies into categories will allow astronomers to study how they relate to each other and provide clues that might help scientists understand how they formed.

For educators and students, STScI is creating an educational website called "Celebrating Hubble's 20th Anniversary." It offers links to facts and trivia about Hubble, a news story that chronicles the observatory's life and discoveries, and the IMAX IMAX
a film projection process that produces an image ten times larger than standard "Hubble 3D" educator's guide. An anniversary poster containing Hubble's "hall-of-fame" images, including the Eagle Nebula and Saturn, also is being offered with downloadable classroom activity information.

To date, Hubble has observed more than 30,000 celestial targets and amassed more than a half-million pictures in its archive. The last astronaut servicing mission to Hubble in May 2009 made the telescope 100 times more powerful than when it was launched.
