An extremely energetic cosmic ray, an extragalactic particle with an energy exceeding about 240 exa-electron volts (EeV) — has been detected by the Telescope Array experiment’s surface detector.
According to the findings, its arrival direction shows no obvious source.
Although low-energy cosmic rays emanate from the sun, the origins of rarer ultrahigh-energy cosmic rays (UHECRs) are thought to be related to the most energetic phenomena in the Universe, such as those involving black holes.
The Telescope Array is a large-scale cosmic ray experiment located in the desert of Millard County, Utah, United States.
It is designed to study the highest-energy particles in the universe, known as ultra-high-energy cosmic rays (UHECRs).
The Telescope Array consists of two main components:
Surface detector array: An array of 507 scintillation surface detectors, each 3 m2 located on a 1.2 km (3/4 mile) square grid. The surface detectors measure the distribution of charged particles at the Earth's surface when an air shower strikes.

Fluorescence detectors: Three fluorescence detectors located on a 30 km triangle. The fluorescence detectors measure the scintillation light generated as the air shower passes through the gas of the atmosphere.
The Telescope Array has observed UHECRs with energies greater than 1018eV, which is more than a hundred million times the energy of the most powerful particle accelerators on Earth.
The origin of these particles is still a mystery, but they are thought to come from the most distant reaches of the universe.
The Telescope Array is a valuable tool for understanding the universe and its origins.
It is also helping to develop new technologies for detecting UHECRs and other high-energy particles.
