Earth hit by most powerful cosmic gamma ray photon blast ever recorded Jasper Hamill Wednesday 31 Jul 2019 10:11am Share this article via facebook Share this article via twitter Share this article via messenger 13 SHARES The Crab Nebula, which is located in an arm of the Milky Way 6,500 light-years from Earth Scientists have recorded the most powerful ‘gamma-ray’ blast to ever hit our planet. The cosmic beam was detected by the Tibet AS-gamma Experiment, a collaboration between Japanese and Chinese researchers. Gamma rays are electromagnetic waves with a very short wavelength which are produced during dramatic events in space such as the death of stars in massive supernova explosions. Other electromagnetic waves include radio waves and microwaves. If a strong gamma-ray hit a human, it could kill them or damage their cells and cause cancer. Luckily, Earthlings are protected from gamma rays, which tend to break apart into small particles when they crash into our atmosphere before showering down on Earth, where they can be detected by scientists.

They also placed 64 concrete barrels filled with water which can also detect the gamma-ray remnants. This experiment allowed to detect the power and source of the gamma-ray photons – the name of the tiny, basic particles in light and other forms of electromagnetic radiation including gamma-rays. They were measured at 100 tera-electron volts (TeV)l, which is one trillion electron volts or roughly 10 times the maximum energy recorded by the Large Hadron Collider when it is used to smash particles together. It was calculated that the photons emanated from the Crab Nebula – a cloud of dust and gas left behind when a star went kaboom in a supernova so bright it was observed by Chinese astronomers working in the 11th century AD. Scientists cannot fully explain why the nebula produces such powerful gamma rays, but it’s believed the system is home to a rapidly spinning star called a pulsar, which rotates at high speeds and emit powerful beams of electromagnetic radiation.
