  2. Background radiation - Wikipedia

    en.wikipedia.org/wiki/Background_radiation

    Displayed background gamma radiation level is 9.8 μR/h (0.82 mSv/a) This is very close to the world average background radiation of 0.87 mSv/a from cosmic and terrestrial sources. Cloud chambers used by early researchers first detected cosmic rays and other background radiation. They can be used to visualize the background radiation

    The European Space Agency's Planck satellite has been gathering data since its launch in 2009, slowly building up a map of the cosmic microwave background radiation -- a distant remnant of the Big ...

  4. Cosmic microwave background - Wikipedia

    en.wikipedia.org/wiki/Cosmic_microwave_background

    The power spectrum of the cosmic microwave background radiation temperature anisotropy in terms of the angular scale (or multipole moment). The data shown comes from the WMAP (2006), Acbar (2004) Boomerang (2005), CBI (2004), and VSA (2004) instruments. Also shown is a theoretical model (solid line).

    en.wikipedia.org/wiki/CMB_cold_spot

    Image generated with Celestia. The circled area is the cold spot in the WMAP. The CMB Cold Spot or WMAP Cold Spot is a region of the sky seen in microwaves that has been found to be unusually large and cold relative to the expected properties of the cosmic microwave background radiation (CMBR).

  6. Cosmic background radiation - Wikipedia

    en.wikipedia.org/wiki/Cosmic_background_radiation

    The Sunyaev–Zel'dovich effect shows the phenomena of radiant cosmic background radiation interacting with "electron" clouds distorting the spectrum of the radiation. There is also background radiation in the infrared, x-rays, etc., with different causes, and they can sometimes be resolved into an individual source. See cosmic infrared ...

  7. Google Earth - Wikipedia

    en.wikipedia.org/wiki/Google_Earth

    Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.

  8. Cosmic infrared background - Wikipedia

    en.wikipedia.org/wiki/Cosmic_infrared_background

    A hitherto unrecognised population of intergalactic stars have been shown to explain the CIB as well as the other elements of the diffuse extragalactic background radiation. If intergalactic stars were to account for all of the background anisotropy, it would require a very large population, but this is not excluded by observations and could in ...

  9. Cosmic Background Explorer - Wikipedia

    en.wikipedia.org/wiki/Cosmic_Background_Explorer

    The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape our understanding of the cosmos.
