  • Interesting fact: It took Leonardo Da Vinci 10 years to paint Mona Lisa. He never signed or dated the painting. Leonardo and Mona had identical bone structures according to the painting. X-ray images have shown that there are 3 other versions under the original.
    • n X-ray ĕks"rā` (Physics) originally, any of the rays produced when cathode rays strike upon surface of a solid (as a copper target or the wall of the vacuum tube); now defined as electromagnetic radiation with a wavelength of 0.1 to 10 nanometers. X-rays are noted for their penetration of many opaque substances, as wood and flesh, their action on photographic plates, and their fluorescent effects. They were called X rays by their discoverer, W. K. Röntgen, but were also referred to for some time as Roentgen rays. The term X-ray has become the most common designation. They also ionize gases, but cannot be reflected, or polarized, or deflected by a magnetic field. They are used in examining objects opaque to visible light, as for imaging bones or other structures inside the human body, and for detecting flaws in metal objects, such as in welds.

The X-ray continuum of Vela X-1 has been studied extensively in X-rays.
The Ionized Stellar Wind in Vela X-1 During Eclipse
The compatibility of the X-ray and γ -ray spectra of SN 1006 supports our notion of an inverse Compton origin of the γ -rays. A con firmation would require the observation of corresponding curvature in the X-ray and TeV γ -ray spectra, though.
Gamma-ray astronomy
Reynolds, 1996), infrared, soft X-ray (estimated from Willinggale et al., 1996), hard X-ray (Ozaki, 1998), GeV γ -rays, and TeV γ -rays are presented (taken from Tanimori et al. (2001)).
Gamma-ray astronomy
The maxima in the count rates in γ -rays and in X-rays apparently coincide, though the X-ray detector had a dropout at the time of the peak in γ -rays.
Gamma-ray astronomy
In case (a) the X-ray beams are wider than the radio beams, therefore, when the line of sight sweeps across the both radio beams (to reproduce the main pulse and the interpulse) it would sweep across the both X-ray beams either, and hence gives double X-ray pulse, which is inconsistent with the observation.
