Astronomers have detected the highest-energy light ever seen, streaming in from near the center of the Milky Way. Hundreds of gamma ray signals were detected with ultra-high energies, with the most ...

Researchers have detected what is now the most energetic light that has ever been found by humans. Astrophysicists have been trying to work out why and how the universe produces this energetic light ...

Blue light has acquired a dubious reputation in recent years, frequently blamed for everything from disrupted sleep patterns to digital eye strain. This high-energy light, emitted abundantly by our ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...

The sweeping beams of cosmic lighthouses called pulsars are much more energetic than previously thought, calling into question the bulbs that power them. A new analysis, from the High Energy ...

A group of international researchers has discovered the highest-energy light ever observed from the sun. In a new paper published last week in the journal Physical Review Letters, scientists found the ...
