A trio of photons emitted seven billion years ago from a gamma ray burst threaten to scrap decades of research by theoretical physicists.

Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. Gamma rays are high-energy photons produced by some of the most violent ...

4. Photons from particle accelerators are used in chemistry and biology. Visible light’s wavelengths are larger than atoms and molecules, so we literally can’t see the components of matter. However, ...

Exceptionally powerful X-ray jets have been detected emanating from two supermassive black holes. These cosmic structures date back to a time when the Universe was still young. These discoveries, ...

Now, this same black hole is once again captivating scientists with an extraordinary gamma-ray flare that’s emitted photons hundreds of billions of times more powerful than visible light.

A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

This light has more energy than the particles smashed in the large ... “We have discovered gamma-ray photons reaching 20 TeV from the Vela pulsar,” the corresponding author for this ...

AEROSPACE ENGINEER EUGEN SÄNGER hypothesized in the 1950s that if matter could be completely converted into light particles (called photons), the photons themselves could be a power source to ...

As long as one is sure all the photons, or particles of light, left their source at exactly the same time, ... "But nothing that we know can un-disperse gamma-ray photons," Nemiroff said.
