PHYSICS NEWS UPDATE
The American Institute of Physics Bulletin of Physics News
Number 319 April 29, 1997 by Phillip F. Schewe and Ben Stein

A NEW CELESTIAL SOURCE OF POSITRONS has been
identified. Positrons (antielectrons) are routinely made on Earth
at several labs (SLAC, LEP, HERA) and in deep space (the
galactic center and cosmic rays). The Gamma Ray Observatory
(GRO) has now found a new positron source. At a meeting in
Williamsburg, VA yesterday, GRO scientists announced the
observation of a diffuse fountain of positron-emitting material
projecting 3000 light years out of the plane of our galaxy. The
researchers are happy to have found a new galactic feature but
are puzzled as to why the flare, starting near or at the core of the
Milky Way, flows north out of the plane but not south. (See
