  2. X-ray background - Wikipedia

    en.wikipedia.org/wiki/X-ray_background

    The galactic X-ray background is produced largely by emission from hot gas in the Local Bubble within 100 parsecs of the Sun. Deep surveys with X-ray telescopes, such as the Chandra X-ray Observatory , have demonstrated that around 80% of the cosmic X-ray background is due to resolved extra-galactic X-ray sources, the bulk of which are ...

    KXRY (91.1 FM) is a non-commercial class D radio station in Portland, Oregon, United States, operating under the name XRAY.fm.It is a mixed-format progressive, independent radio station which broadcasts progressive talk radio, cultural programs, and music of a wide variety of genres played by its disc jockeys.

  4. X-ray binary - Wikipedia

    en.wikipedia.org/wiki/X-ray_binary

    X-ray binaries are a class of binary stars that are luminous in X-rays. The X-rays are produced by matter falling from one component, called the donor (usually a relatively common main sequence star ), to the other component, called the accretor , which is either a neutron star or black hole .

  5. Astrophysical X-ray source - Wikipedia

    en.wikipedia.org/wiki/Astrophysical_X-ray_source

    The X-ray colors represent the temperature of the X-ray emission from each star: hot stars are blue-white and cooler stars are yellow-red. The brightest object in the optical image is the full moon, which is also in the X-ray image. The X-ray image was actually obtained by the ROSAT satellite during the All-Sky Survey phase in 1990–1991.

  6. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.

    Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.

  8. X-ray specs - Wikipedia

    en.wikipedia.org/wiki/X-ray_specs

    X-Ray Specs were long advertised with the slogan "See the bones in your hand, see through clothes!" Some versions of the advertisement featured an illustration of a young man using the X-Ray Specs to examine the bones in his hand while a voluptuous woman stood in the background, as though awaiting her turn to be "X-rayed".

  9. X-ray pulsar - Wikipedia

    en.wikipedia.org/wiki/X-ray_pulsar

    An X-ray pulsar is a type of binary star system consisting of a typical star (stellar companion) in orbit around a magnetized neutron star.The magnetic field strength at the surface of the neutron star is typically about 10 8 Tesla, over a trillion times stronger than the strength of the magnetic field measured at the surface of the Earth (60 μT).
