It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

Scientists have long known that thunderstorms can produce gamma rays, extremely high-energy light that is more often associated with astrophysical phenomena, such as exploding stars and matter ...

Microscopy techniques based on electrons and X-ray photons have been used to 'look' inside matter for decades. In the past few years, advances in instrumentation and software have led to ...

Using the Large High-Altitude Air Shower Observatory (LHAASO), an international team of astronomers have detected very-high-energy (VHE) gamma-rays around the pulsar PSR J0248+6021, which may be ...

Research done at a mountaintop cosmic-ray observatory in Armenia has shed new light on how thunderstorms can create flashes of gamma rays by accelerating electrons. Further study of the phenomenon ...

What is Scanning Transmission X-ray Microscopy (STXM)? Scanning Transmission X-ray Microscopy (STXM) is a powerful imaging technique that combines the principles of X-ray spectroscopy and microscopy ...

What is Scanning X-Ray Fluorescence (XRF) Microscopy? Scanning X-Ray Fluorescence (XRF) Microscopy is a powerful analytical technique that enables the visualization and quantification of the elemental ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
