Astronomers Find First Ever Gamma Ray Clock
Bonn, Germany (SPX) Nov 28, 2006
Astronomers using the H.E.S.S. telescopes have discovered the first ever modulated signal from space in Very High Energy Gamma Rays -- the most energetic such signal ever observed. Regular signals from space have been known since the 1960s, when the first radio pulsar (nicknamed Little Green Men-1 for its regular nature) was discovered.
