REVIEW ARTICLE The NASA Spitzer Space Telescope
The National Aeronautics and Space Administration’s Spitzer Space Telescope formerly the Space Infrared Telescope Facility is the fourth and final facility in the Great Observatories Program, joining Hubble Space Telescope 1990 , the Compton Gamma-Ray Observatory 1991–2000 , and the Chandra X-Ray Observatory 1999 . Spitzer, with a sensitivity that is almost three orders of magnitude greater tha...
متن کاملThe Spitzer Space Telescope First-Look Survey: Neutral Hydrogen Emission
The Spitzer Space Telescope (formerly SIRTF) extragalactic First-Look Survey covered about 5 deg centered on J2000 α = 1718, δ = 5930 in order to characterize the infrared sky with high sensitivity. We used the 100-m Green Bank Telescope to image the 21 cm Galactic H I emission over a 3 × 3 square covering this position with an effective angular resolution of 9.8 and a velocity resolution of 0....
متن کاملSpitzer Space Telescope Mid-ir Light Curves of Neptune
We have used the Spitzer Space Telescope in February 2016 to obtain high cadence, high signal-tonoise, 17-hour duration light curves of Neptune at 3.6 and 4.5 μm. The light curve duration was chosen to correspond to the rotation period of Neptune. Both light curves are slowly varying with time, with full amplitudes of 1.1 mag at 3.6 μm and 0.6 mag at 4.5 μm. We have also extracted sparsely samp...

متن کاملFreshly Formed Dust in the Cassiopeia a Supernova Remnant as Revealed by the Spitzer Space Telescope
We performed Spitzer Infrared Spectrograph mapping observations covering nearly the entire extent of the Cassiopeia A supernova remnant (SNR), producing mid-infrared (5.5Y35 m) spectra every 500Y10 00. Gas lines of Ar, Ne, O, Si, S, and Fe, and dust continua were strong for most positions. We identify three distinct ejecta dust populations based on their continuum shapes. The dominant dust cont...
