Cartwheel Galaxy
This false-color composite shows the Cartwheel galaxy as seen by the Galaxy Evolution Explorer (blue); the Hubble Space Telescope (green); the Spitzer Space Telescope (red); and the Chandra X-ray Observatory (purple). Approximately 100 million years ago, a smaller galaxy plunged through the heart of Cartwheel galaxy, creating ripples of brief star formation.

PASADENA, Calif. -- A collection of NASA missions will be involved in a live event Friday, April 3, that will allow the public to get an inside look at how these missions are run. "Around the World in 80 Telescopes" is a 24-hour webcast that is part of the "100 Hours of Astronomy" event for the International Year of Astronomy 2009.

During the webcast, viewers will be able to visit some of the most advanced telescopes on and off the planet. For NASA's space-based missions, the webcast will be broadcast from control centers throughout the United States. To view the webcast, visit http://100hoursofastronomy.org/ .

As part of the webcast, most of the missions will release a never-before-seen image from the telescope or observatory. The new images can be found on the Web sites listed below. Please note these times correspond to the beginning of each mission's segment on the live webcast and when each new image will be available.

NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington. Science operations are conducted at the Spitzer Science Center at the California Institute of Technology, also in Pasadena. Caltech manages JPL for NASA. Graphics and more information about Spitzer are online at http://www.spitzer.caltech.edu/spitzer and http://www.nasa.gov/spitzer .

Caltech leads the Galaxy Evolution Explorer mission and is responsible for science operations and data analysis. JPL manages the mission and built the science instrument. The mission was developed under NASA's Explorers Program managed by the Goddard Space Flight Center, Greenbelt, Md. Researchers sponsored by Yonsei University in South Korea and the Centre National d'Etudes Spatiales (CNES) in France collaborated on this mission.
