When the Event Horizon Telescope (EHT) unveiled the first image of a black hole in 2019, the world got its first glimpse into ...

Gamma rays are the highest-energy form of electromagnetic radiation, billions of times more energetic than visible light.

Scientists with the HESS Observatory have identified the most energetic cosmic electrons ever observed. What could this mean ...

Yet, compared to the results of standard physics models derived from particle accelerator experiments such as at the Large Hadron Collider and the Super ... the high-energy cosmic ray particle ...

Secondly, space-based instruments are too small to capture enough of these particles, partly due to the particles' uneven energy distribution in space. In other words, cosmic ray sources ...

The galaxy M87, located in the Virgo constellation, provided the first-ever photo of a black hole in 2019, when the Event Horizon Telescope captured an image of the supermassive black hole at the ...
