A team of scientists from Japan's RIKEN Center for Advanced Photonics have revealed how carbon nanotubes emit more energetic light than the light they absorb. Since materials typically emit less ...

Every now and again, the night sky lights up with a spectacular explosion that blazes with the most energetic light our Universe can produce. Known as gamma-ray bursts, they can release in a few ...

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 ...

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 ...

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 ...

The cosmos keeps outdoing itself. Extremely energetic light from space is an unexplained wonder of astrophysics, and now scientists have spotted this light, called gamma rays, at higher energies than ...

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 ...
