SUMMARY:Our Changing View of the TeV Sky\, Physics Department Colloqui
 um\, Jordan Goodman\, University of Maryland
DESCRIPTION:The advent of ground-based atmospheric and water Cherenkov
  gamma-ray detectors\, as well as\, the Compton and Fermi satellites h
 as revolutionized our view of the TeV sky. Twenty years ago there was 
 only one known TeV gamma-ray source\, the Crab. Today there are well o
 ver 100 detected sources - steady and variable\, point-like and diffus
 e. We have also made great strides studying Gamma Ray Bursts\, the mos
 t energetic processes in the Universe. Most recently\, we have even di
 scovered that charged TeV cosmic rays have unexpected anisotropies in 
 their arrival directions suggesting the existence of local cosmic ray 
 sources. The next generation detectors\, CTA\, HAWC and\, IceCube will
  undoubtedly give us a better understanding of these exciting phenomen
 a and almost certainly reveal more surprises.  In this talk\, I will r
 eview some of these results and show results from the Milagro gamma ra
 y observatory. In addition I describe our next generation HAWC observa
 tory currently under construction at high-altitude in Mexico.
