An international team of scientists from the VERITAS collaboration detected pulsed gamma-ray emissions from the Crab nebula at far higher energies than expected. The highly energized gamma rays are coming from an extreme object at the Crab Nebula’s center known as a pulsar This particular pulsar lives at the center of the Crab Nebula… the remnants of a stellar explosion, or supernova, that was recorded by Native American and Chinese astronomers in 1054.

Researchers recently found gamma rays with energies exceeding 100 billion electron- volts, higher energy levels than the current theoretical models can explain.
Andrew McCann, co-author of the study, said the findings were totally unexpected and ‘absolutely jaw-dropping.’
Instead of being baffled by the intense radiation, scientists are excited about redefining how these small, dense objects give off so much light.
Martin Schroedter of the Harvard-Smithsonian Center for Astrophysics said, “If you asked theorists a year ago whether we would see gamma-ray pulses this energetic, almost all of them would have said, ‘No.’ There’s just no theory that can account for what we’ve found.”
Typically, pulsars are ejected from the stellar wreckage during a supernova. But in the case of the Crab system, the pulsar remained at its center, producing radiation that covers the entire electromagnetic spectrum.
The emissions were detected by the VERITAS research program in Arizona.

VERITAS, which began collecting full-scale observations in 2007, is used to examine the remains of exploded stars, distant galaxies and powerful gamma-ray bursts and to search for evidence of mysterious dark matter particles.
