The recently discovered cosmic ray — which was first detected on May 27, 2021 at the Telescope Array in Millard County, Utah – had an estimated energy of 240 EeV.

What happens when two rare ring galaxies collide? They form an infinity symbol—or the face of a cosmic owl, depending on how ...

Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.

Two international teams zoned in on a potential answer to a decades-long mystery surrounding ephemeral cosmic X-rays.

The Telescope Array is uniquely positioned to detect ultra-high-energy cosmic rays. It sits at about 1,200 m (4,000 ft), the elevation sweet-spot that allows secondary particles maximum ...

Once completed, 500 new detectors will allow the Telescope Array to capture cosmic ray-induced particle showers across 2,900 square kilometers (about 1,120 square miles) — an area nearly the ...

Astronomers have traced a mysterious blast of X-rays to a star that, like a cosmic action hero, just refused to die.

The Telescope Array project is already off to a good start. In 2014, the project noticed that cosmic rays seemed to be in a greater cluster in the sky just south of the Big Dipper. "What we're ...

The $25 million Telescope Array cosmic ray observatory was built to detect these high-energy visitors, known as cosmic rays, whose origin remains a mystery. The observatory is a joint venture of ...

Names are a strange thing in astronomy. Sometimes scientists come up with grandiose, simple name, like the Extremely Large ...
