Using data from NASA's Kepler telescope, Russian astronomers have investigated an X-ray binary known as Scorpius X-1 (or Sco X-1 for short). Results of the study, published September 2 on the arXiv pre-print repository, provide ...
Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion-year lifetime. These transient phenomena present one of the most ...

Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the ...
A nanocomposite that absorbs X-rays and then, with nearly perfect efficiency, re-emits the captured energy as light, could help to improve high-resolution medical imaging and security screening. The material's near-100 percent ...
