Abstract

The Fermi Space Telescope observing the whole sky every three hours in gamma-ray energy range, from few KeV to 100's of GeV, has been spectacularly successful and has provided some unexpected results along with great deal of new data on astrophysical sources that it was designed to observe. I will describe some basic characteristics of the telescope and list all the areas of astrophysics where it has made a significant contributions. I will discuss in more detal several of the most spectacular results, such as Gamma-ray flares from crab nebula, Gamma-ray Bursts and limits on Lorentz Invariance, and limits on Dark Matter. I will also describe observation and new results in areas where I have personally had major interest. Among these are Cosmic ray electrons and positrons, Clusters of Galaxies, Blazars and Cosmic Gamma-ray Background Radiation, and Solar Flares.
