For years, astronomers have tried to place telescopes above atmosphere, to catch a glimpse of an otherwise hidden infrared universe. This section explores the heritage of infrared astronomy, which culminates with NASA's Spitzer Space Telescope, the most sensitive infrared space observatory ever launched. Learn about infrared astronomy's:
NASA's Spitzer Space Telescope is a technological marvel, featuring many innovations never before used on a space mission. It may seem like a contradiction, but Spitzer needs to be simultaneously "cold" and "warm" to function properly. Learn how Spitzer achieves this balance with the:
The Universe is continually radiating a wealth of information to Earth, sending signals in a wide-spectrum of light. However, not all of these messages reach the ground. In space, any object that has a temperature above zero Kelvin (- 459.67 degrees Fahrenheit, or -273.15 degrees Celsius) radiates in the infrared. Learn how NASA's infrared Spitzer Space Telescope contributes to the study of:
Ten years after a Delta II rocket launched NASA's Spitzer Space Telescope, lighting up the night sky over Cape Canaveral, Fla., the fourth of the agency's four Great Observatories continues to illuminate the dark side of the cosmos with its infrared eyes.
NASA is extending three missions affiliated with the Jet Propulsion Laboratory in Pasadena, Calif. -- Kepler, the Spitzer Space Telescope and the U.S. portion of the European Space Agency's Planck mission -- as a result of the 2012 Senior Review of Astrophysics Missions.
NASA's Spitzer Space Telescope has been awarded the prestigious 2011 Stellar Award by the Rotary National Award for Space Achievement Foundation, which recognizes missions whose accomplishments hold the greatest promise for furthering future activities in space.
NASA's Spitzer Space Telescope team has been selected to receive the 2010 Maria and Eric Muhlmann Award from the Astronomical Society of the Pacific.
On Friday, Oct. 23, engineers with NASA's Spitzer Space Telescope successfully swapped the spacecraft from the main nitrogen thruster string to a backup thruster string.
Testing and characterization activities continue for NASA's Spitzer Space Telescope warm mission, a process that began after the observatory's cryogen ran out on May 15.
