Astronomers have made a shocking discovery that’s rewriting the way we think about cosmic powerhouses. While scientists ...

According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic ...

In the earliest moments of the Universe, the first photons were trapped in a sea of ionized gas. They scattered randomly with ...

A 3D map of our cosmic neighborhood has revealed hot and cold regions as well as an "escape tunnel" from our local bubble.

These telescopes would be connected to a different set of detectors to measure some property of the arriving cosmic photons, such as their arrival time, to electronically switch the entangled ...

there is hope that studying these ‘photons from hell next door’ will provide insight into the internal workings of their vastly more powerful cosmic cousins.

Gamma rays around this energy level are known to zip around the cosmos, but scientists thought they mostly originated in ...

Roughly 400,000 years after the Big Bang, the universe cooled just enough to allow photons to escape from the primordial cosmological soup. Over the next 14 billion years, these ancient photons ...
