High energy gamma rays on the sun, as observed by NASA's Fermi Gamma-ray Space Telescope. Yellow and orange represent areas where gamma energy is more concentrated. (NASA Solar Dynamics ...

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 ...

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 ...

The upcoming solar maximum may help scientists solve the puzzle of why the sun's poles emitted ten times more high-energy radiation than expected during the last peak in activity.

Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt (TeV ...

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.

Schematic showing the Milky Way, the gamma-ray-emitting Fermi Bubbles (pink), and the Sagittarius dwarf galaxy and its tails (yellow/green). From the position of the Sun, we view the Sagittarius ...

Gamma-ray bursts were traced to the nucleus of an ancient galaxy about 3 billion light-years away from Earth.
