NASA's Hubble Space Telescope is going to celebrate its 25th anniversary on April 24 and the California-based space agency has decided to mark the day in a big way.

As part of the celebrations, NASA has invited the public to join celebrations around the nation and other parts of the world. "Hubble 3D," an IMAX movie telling the story of the world's best-known space telescope, will be screened at theaters throughout the United States.

The Smithsonian Institution-managed National Air and Space Museum will be featuring the Hubble observatory in a number of displays shown through the end of April.

"On April 23 from 9 to 9:45 a.m. EDT, NASA will unveil the official Hubble 25th anniversary image at the Newseum in Washington. NASA Administrator Charlie Bolden, Associate Administrator for the Science Mission Directorate John Grunsfeld, and Hubble Senior Project Scientist Jennifer Wiseman, will speak about Hubble's achievements," NASA posted in an announcement.

David Gaynes, director of the soon-to-be-released documentary on Hubble Space telescope called "Saving Hubble", said, "Hubble's wide support among the general public, to say nothing of the space and astronomy communities, is obviously a testament to the success of the mission, but the achievement of Hubble is even greater than the sum of all the science and wonder the mission has generated - so great it's hard to articulate the feeling, though so many of us recognize it and attempt to describe it."
