 Researchers in Utah have discovered a rare cosmic ray that they think originated outside of the Milky   Way.

Taking the name of the Japanese sun goddess, "Amaterasu particle," it has been given.

A representative for Telescope Array referred to the particle's origin as a "mystery."

Researchers studying space science at the Universities of Utah and Tokyo have discovered an extremely rare, ultra-high-energy cosmic ray that they believe originated outside of the Milky Way galaxy.

Known as the "Amaterasu particle" after the sun goddess of Japan, it is an undetectable subatomic particle.

The results, which were released in the journal Science, show that its energy is comparable to that of the "Oh-My-God" particle, which set a record in 1991.

Co-speaker for Telescope Array and study co-author John Matthews stated: "When it comes to the Oh-My-God particle and this new particle, you can follow their paths back to their sources and nothing with high enough energy could have created them. What the heck is going on is the riddle behind this.

Charged particles known as cosmic rays, which are always present on Earth, mostly come from the sun. High-energy cosmic rays, such as the Amaterasu particle, are considered to originate from extragalactic and other galaxies, however they are an exception.

The Telescope Array, an observatory in Utah's West Desert, recognized the newly found particle. With 507 surface detectors across 270 square miles, the satellite observation station witnessed around 30 ultra-high-energy cosmic ray events, with the Amaterasu particle emerging as the most noteworthy one.

When it struck the atmosphere on May 27, 2021, it set off 23 surface detectors. Its calculated energy was roughly 244 exa-electron volts, which was not quite as high as the 320 exa-electron volts of the "Oh-My-God" particle.

The Amaterasu particle and the other detected particles appear to come from emptiness or voids.

Such ultra-high-energy particles seem to originate from virtually empty areas, in contrast to low-energy cosmic rays, whose sources may be tracked. The Local Void, a barren area that borders the Milky Way galaxy, is thought to be the source of the Amaterasu particle.

The Telescope Array's expansion presents a chance to learn more about this unusual occurrence. Almost the size of Rhode Island is covered by another 500 detectors at the observatory, which is intended to record particle showers caused by cosmic rays and shed more light on cosmic riddles.
