Crab Nebula Blasted Earth With The Highest Energy Gamma Rays
Around 7,500 years ago, a massive stellar explosion occurred within the Perseus Arm of the Milky Way, some 6,500 light-years from Earth. Astronomers first noticed this explosion within the ancient sky back in 1054 as a point of light which slowly faded away, leaving behind an enormous cloud of gas and dust. These remnants can be seen today and are referred to as the "Crab Nebula" and deep within the center of the cloud lies a really powerful, rapidly spinning neutron star.
It lately blasted Earth with the highest energy gamma rays ever detected from an astrophysical source.
In work printed in Physical Review Letters on July 29, astronomers have detailed the detection of this mega energy blast by a particular observatory located 4,300 meters (14,000 feet) above sea degree, within the mountains of Tibet. The Tibet air shower array, because its known, is made up of a series of underground pools, tuned to detect high energy cosmic particles that collide with the Earth.
Because it happens, the extremely dense, spinning neutron star at the center of the Crab Nebula has the facility necessary to accelerate these cosmic particles and fling them at the Earth. Nevertheless, the particles arent going to scorch a gap through your physique if they hit you, as a result of once they smash into particles within the Earths atmosphere they break down into a rain of subatomic particles. That rain is what the Tibet air shower array, with its 600 plus detectors, is able to observe.
