Astronomers have spotted gamma ray emissions coming from the Crab Pulsar at far higher energies than expected.

This challenges notions of how these powerful electromagnetic rays - like light, but far more energetic - are formed, researchers suggest in Science.

They found emissions at more than 100 gigaelectronvolts - 100 billion times more energetic than visible light.

The Crab Nebula that hosts the pulsar continues to amaze astronomers, despite being one of the most studied objects.

The remnant of a supernova that lit up the skies on Earth in 1054, it has been taken in modern times to be a constant source of light - so constant that telescopes were trained on it for calibrations.

But earlier this year, the Crab was spotted emitting gamma-ray flares that have confounded astronomers.

Within the nebula lies the Crab Pulsar - a tiny, rapidly spinning neutron star that sprays highly energetic electromagnetic rays out at its poles like a lighthouse beam, sweeping past the Earth 30 times a second.

The pulsar's enormous magnetic field is known to gather up particles and accelerate them - in a process much like particle accelerators here on Earth.

As those particles move in curved paths, they emit the gamma rays that we can measure.

How frikin hard is it to get frikin crabs with frikin LASER BEAMS attached to their heads?

(Anyone else think of War of the Worlds all of a sudden?)

first it must be sharks with lasers on their head

First thought:

Har-har and I'm an I dare call myself an optical engineering major.
