SUMMARY:Seven Years of Wise\, Astronomy Colloquium\, Ned Wright\, UCLA
DESCRIPTION:WISE\, the Wide-field Infrared Survey Explorer\, surveyed 
 the entire sky in 4 mid-infrared bands at 3.4\, 4.6\, 12 and 22 micron
 s with vastly greater sensitivity than previous all-sky surveys at the
 se wavelengths. WISE surveyed everything more than 1 AU from the Sun\,
  including asteroids\, comets\, nearby brown dwarfs and star forming r
 egions both in the Milky Way and in distant galaxies. The 12 and 22 mi
 cron channels were very powerful for detecting Ultra-Luminous Infrared
  Galaxies\, and WISE has detected some of the most luminous galaxies i
 n the Universe. The WISE short wavelength channels are very powerful f
 or detecting old cold brown dwarfs\, and WISE has detected objects as 
 cool as 250 K\, and the 3rd and 4th closest stellar systems to the Sun
 . WISE was launched 14 Dec 2009 and completed 4-band full sky coverage
  on 17 July 2010. "Warm WISE" ran with its 3.4 & 4.6 micron bands unti
 l 1 Feb 2011. "Warm WISE" was reactivated as NEOWISE-R to search for m
 ore Near Earth Objects\, and has surveyed from 13 Dec 2013 to the pres
 ent\, but the decay of its orbit will shortly end its useful lifetime.
  Future space missions like NEOCam and the Origins Space Telescope can
  achieve orders of magnitude improvements in sensitivity over warm tel
 escopes like HST\, Herschel and WFIRST by using cold optics and modern
  detectors.<br><br>
