Summary
DescriptionA Quarter Century of Infrared Astronomy.jpg |
English: Infrared astronomy, especially from space, explores up a vast portion of the spectrum beyond the red end of visible light. Through this window the universe emits a tremendous variety of information about the physical and chemical composition of various regions, about their energetic states, and about the current and historical activity of star formation. Infrared and submillimeter wavelengths still hold the most promise for studying the earliest moments in the history of the universe when diffuse gas was transformed into the first stars and galaxies. This era is thought to have occurred around the first percent of the age of the universe.
While celebrating this rich legacy of infrared astronomy, infrared astronomers are also enjoying a golden age of sorts, with an unprecedented number of missions currently in-flight: NASA's Spitzer Space Telescope is continuing its warm mission; the European Space Agency Herschel and Planck telescopes are in their prime mission phase; NASA's Wide Field Infrared Survey Explorer (WISE) just launched and is expected to start mapping the sky in early 2010. All of these missions have links to IPAC. I The Spitzer Space Telescope is an infrared observatory built and operated by the Jet Propulsion Laboratory of the California Institute of Technology for the U.S. National Aeronautics and Space Administration. It was launched on 25 August 2003 into a Sun-centered orbit, and ran out of the liquid helium that kept it cold on 15 May 2005. Today, it still observes the cosmos at 3.6 and 4.5 m, using one out of three original instruments. The picture shows 3.6 m emission as blue, 8 m as green, and 24 m as red. Dust glows with different colors depending on its composition and heating, whereas the colors of the stars indicate their age, blue for mature stars, and red for those still surrounded by natal cloud material. The field of view is again about 3/4 of a degree on a side. In early 1998, IPAC was designated as the science operations center for the Spitzer Space Telescope, NASA's Infrared Great Observatory. The Spitzer Science Center (SSC), is an autonomously managed entity within IPAC, which relies on the skills and knowledge of IPAC experts in supporting Spitzer. |
