Latest Fred Lawrence Whipple Observatory Stories
Astrophysicists have detected pulsed gamma-ray emissions from the Crab pulsar with energies that exceed 100 billion electron-volts (GeV). These gamma-ray pulses surpass what current theoretical models of pulsars can explain.
An international collaboration of 390 scientists reports the discovery of an outburst of very-high-energy (VHE) gamma radiation from the giant radio galaxy Messier 87 (M 87), accompanied by a strong rise of the radio flux measured from the direct vicinity of its super-massive black hole.
Astronomers announced that they have penetrated the heart of the universe's most powerful explosion -- a gamma-ray burst (GRB) -- using the PAIRITEL (Peters Automated Infrared Imaging Telescope) robotic telescope on Mt. Hopkins, Arizona.
