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:
Engineers are studying data returned by NASA's Spitzer Space Telescope, to determine what caused the observatory to enter safe mode on Friday, Aug. 18 at 2:52 p.m. Pacific time. After an unexpected reboot of Spitzer's main onboard computer, the spacecraft autonomously followed pre-programmed procedures, switched to the backup electronics system, and entered safe mode. The engineering and science teams have so far found no hardware or software problem to explain the unplanned reboot. In response to the safe mode entry, the Spitzer team has carefully maneuvered the spacecraft, which is in an Earth-trailing orbit around the sun, to point its high-gain antenna toward Earth. This change in attitude enables engineers to receive critical engineering data as quickly as possible. The project's engineers are carefully analyzing the data, trying to determine the next course of action to bring the spacecraft back to nominal operations.
Dr. Michael Werner, project scientist of NASA's Spitzer Space Telescope, has been selected to give the Royal Astronomical Society's distinguished 2006 George Darwin Lecture.
Self-help books and grade school teachers have been promoting this tip for decades: To keep success in sight, make a list of goals.
Among the thousands of top interdisciplinary scientists, policy makers, journalists, and general science enthusiasts who are gathering in St. Louis, Mo. from February 16-20 for the 2006 American Association for the Advancement of Science (AAAS) meeting is Spitzer Space Telescope Project Scientist Dr. Michael Werner.
When Doreen Spitzer learned that her son was going to visit the science center named after her late husband, Dr. Lyman Spitzer, Jr., she asked for two things: a Spitzer Space Telescope calendar and a comprehensive report of the visit.
It's another sunny Tuesday morning in Southern California and a handful of infrared scientists have flocked to the roof of the Spitzer Science Center for this week's "First Seven Minutes" meeting.
Four days after its launch on August 25, 2003, NASA's Spitzer Space Telescope opened its infrared eyes for the first time and immediately performed beyond all expectations by providing the world with one of the deepest infrared images ever taken. Two years later, Spitzer continues to surpass expectations by uncovering a hidden universe teeming with warm stellar embryos, chaotic planet-forming disks, majestic galaxies, hidden black holes, remnants of dead stars, and much more.
On August 15, 2005 at approximately 7:11 p.m. Pacific Daylight Time, NASA's Spitzer Space Telescope will begin its 10,000th hour of science observations.
For the second time, Spitzer Legacy science teams have released their most recent data and value-added projects to the public via the World Wide Web.
