SUMMARY:The new world of Gamma Ray Astronomy\, Astronomy Colloquium\, 
 Lucy Fortson\, University of Minnesota
DESCRIPTION:With the third generation ground-based gamma-ray telescope
 s delivering over a hundred new TeV emitting objects and with the new 
 Fermi satellite providing greatly improved sensitivity in the GeV ener
 gy regime\, gamma ray astronomy is entering a golden age. I will first
  review the basics of ground-based gamma-ray astronomy and the Air Che
 renkov Telescope method of detection. I will then describe VERITAS - a
 n array of four gamma ray telescopes located at Mt. Hopkins\, Arizona 
 - and some of the recent results from the first few years of the VERIT
 AS observing program\, paying attention to the observations of several
  new TeV emitting active galactic nuclei. I will close with a look at 
 the future of ground-based gamma ray astronomy with the CTA - the prop
 osed array of 36-100 Cherenkov Telescopes.<br>
