Astrophysicists Zero In on Source of Strange Gamma-Ray Signals
Millisecond pulsar binaries may produce the excess 511 keV photons seen in the galaxy. These systems could expose hidden pulsars and even exoplanets. Many astrophysicists devote their work to tracing the origins of photons, since certain types are closely linked to specific cosmi...
