TL;DR: The Spitzer Space Telescope, NASA's great Observatory for infrared astronomy, was launched 2003 August 25 and is returning excellent scientific data from its Earth-trailing solar orbit as mentioned in this paper.

TL;DR: In this paper, the IRAS Revised Bright Galaxy Sample (RBGS), a complete flux-limited survey of all extragalactic objects with total 60 μm flux density greater than 5.24 Jy, covering the entire sky surveyed by IRAS at Galactic latitudes > 5°.

TL;DR: The Infrared Astronomical Satellite (IRAS) as discussed by the authors consists of a spacecraft and a liquid helium cryostat that contains a cooled IR telescope, whose focal plane assembly is cooled to less than 3 K, and contains 62 IR detectors in the survey array.

TL;DR: In this article, the authors use the Spitzer Space Telescope First Look Survey (FLS) to assess the fraction of active galactic nuclei (AGNs) with mid-infrared luminosities that are comparable to quasars and that are missed in optical quasar surveys because of dust obscuration.

TL;DR: In this paper, the spectral absorption lines in one of the high-velocity stars in the vicinity of the Galaxy's central supermassive black hole have been detected, indicating that the star is behind the black hole at the time of closest approach and countervolving against the Galaxy.
