Energy levels of Crab Pulsar defy explanation

An international team of scientists has detected pulsed gamma rays from the neutron star at the heart of the Crab Nebula with energies far higher than theoretical pulsar models can explain. The emissions were detected by the VERITAS (Very Energetic Radiation Imaging Telescope Array System) array of four 12-meter Cherenkov telescopes in Arizona and the […]

Fermi Telescope reveals new type of pulsar

A new class of pulsar detected by NASA’s Fermi Gamma-ray Space Telescope is solving the mystery of previously unidentified radio-quiet gamma-ray sources. The report in Science describes 16 pulsars discovered by Fermi based only on their emissions of high-energy gamma rays. Previously, most of the 1,800 known pulsars were found through their periodic radio emissions. […]

Plethora Of Pulsar Poles Perplexes Physicists

Physicists using the Arecibo Telescope in Puerto Rico have uncovered radio interpulses from the Crab Nebula pulsar that feature never-before-seen radio emission spectra. The discovery has led scientists to speculate that this could be the first cosmic object with a third magnetic pole. “We never see the strange frequency structure in the main pulse and […]
