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 ...

An undated artistic impression depicts the effect of a powerful blast of gamma rays that provoked a significant disturbance in Earth’s ionosphere, the result of a gamma-ray burst (GRB) from a ...

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 ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

The sun also emits much more powerful gamma rays, which are the most energetic waves on an electromagnetic spectrum. Each gamma ray photon carries a billion times as much energy as an ultraviolet ...

Gamma rays are the most energetic form of electromagnetic radiation. In just a few seconds, a gamma-ray burst blasts out the same amount of energy that the Sun will radiate throughout its entire life.

It was previously predicted that the Sun could produce gamma rays – electromagnetic radiation with the highest energy – through interactions with cosmic rays from distant sources, ...

Gamma-ray bursts were traced to the nucleus of an ancient galaxy about 3 billion light-years away from Earth. By Laura Baisas Published Jun 23, 2023 9:00 AM EDT Get the Popular Science daily ...

Electromagnetic waves emerge from the invisible currents flowing through the dynamic fabric of space-time, woven tightly between galaxies, stars, and dark matter. This visual journey reveals how ...

Because those effects last longer than that of gamma rays, it could be more lethal, according to Space.com — although, the Earth would need to be close, about 16 light years away, to feel it.

The forthcoming solar maximum of the current solar cycle that began in Dec. 2019, , solar cycle 25, could help explain why the sun shined brighter in gamma rays at its poles during the peak ...
