New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a ...

Gamma rays are much shorter in wavelength than visible ... Astronomers have sent x-ray telescopes into orbit to scan the sky, to catch the first x-ray afterglow of a burst as soon as possible.

equipped with gamma ray detectors, will hover at half the height of the High Roller on Dec. 29 and Dec. 31. It’s a technology used before major events, including a scan done recently in ...

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 ...

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...

A new way to locate peat soils using gamma ray detectors mounted on aircraft has been developed by Irish scientists. Most of Ireland’s peatlands emit carbon because of land drainage and peat ...

The research modeled cancer risk in 61.5 million U.S. patients who had undergone CT scans, estimating that around 103,000 cancer cases could eventually result from the radiation exposure over their ...

CT scans are vital for effectively diagnosing ... short-wavelength radiation that includes ultraviolet (UV), X-rays and gamma rays. These are more energetic than visible light.
