Description: <jats:title>A Nova Source of Gamma Rays</jats:title> <jats:p> Novae are thermonuclear explosions that occur at the surface of a white dwarf when material is pulled onto it from a companion star in a binary system. They are different from supernovae because the explosion does not completely destroy the white dwarf. Novae have not been widely considered as high-energy gamma-ray sources. Using the Fermi Large Area Telescope, <jats:bold> Abdo <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="817" related-article-type="in-this-issue" vol="329" xlink:href="10.1126/science.1192537">817</jats:related-article> ) now report the detection of a nova explosion in gamma rays. The observations provide evidence for the acceleration to relativistic energies of particles in the shock wave following the explosion. </jats:p>
