The effects of this gamma-ray burst were studied with the help of the China Seismo-Electromagnetic Satellite (CSES), also called Zhangheng, a Chinese-Italian mission launched in 2018.

On the other side of the spectrum, light with wavelengths slightly shorter than 380 nanometers is known as ultraviolet. Beyond that come X-rays and beyond that still come gamma rays.

SAN FRANCISCO — The most energetic particles in the electromagnetic spectrum could pose a danger to commercial airline passengers. About every 3000 hours of flying time, a plane is hit with a ...

GRBs emit light across the entire electromagnetic spectrum — from radio waves to gamma rays — and the 2019 burst pumped as much energy into its extreme gamma-ray photons as it did into its ...

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the ...

A new NASA animation shows what the sky over Earth would look like to humans if we had evolved to see high-energy gamma-ray light rather than just the visible light spectrum.

Gamma rays are the most energetic waves of light on the electromagnetic spectrum. Large bursts of gamma radiation from distant galaxies can help us learn about the volatile early days of the universe.

And while lasers can now produce coherent light in the visible, ultraviolet, and x-ray ranges of the electromagnetic spectrum, doing so beyond the x-ray range—which is where gamma rays exist ...

Scientists using the H.E.S.S. observatory in Namibia have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera ...

A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our galaxy dubbed the “Fermi bubbles”, has puzzled astronomers since it was ...
