what is the origin of the cosmic background radiation

Electromagnetic radiation from the Big Bon

Temperature of the cosmic background radiation spectrum based happening COBE data: uncorrected (upside); corrected for the dipole term expected to our peculiar velocity (intermediate); corrected for contributions from the dipole term and from our galaxy (bed).

Natural object background radiation syndrome is nonparticulate radiation from the Big Bang. The line of descent of this radiation depends on the region of the spectrum that is observed. One component is the cosmic microwave downpla. This component is redshifted photons that have freely streamed from an era when the Universe became limpid for the first metre to radioactivity. Its discovery and detailed observations of its properties are considered one of the major confirmations of the King-size Bang. The find (by chance in 1965) of the CBR suggests that the archaean universe was dominated past a radiation field, a field of extremely heat and pres.^[1]

The Sunyaev–Zel'dovich effect shows the phenomena of bright cosmic background radiation interacting with "electron" clouds distorting the spectrum of the radioactivity.

There is also background radiation in the infrared, x-rays, etc., with different causes, and they can sometimes represent solved into an soul source. See large infrared light background and X-ray background. Experience also cosmic neutrino background and collection background light.

Timeline of significant events [edit]

1896: Charles Édouard Guillaume estimates the "radiation of the stars" to be 5.6 K.^[2]

1926: Sir Arthur Eddington estimates the non-energy radiation of starlight in the galaxy has an effective temperature of 3.2 K. [1]

1930s: Erich Regener calculates that the not-caloric spectrum of cosmic rays in the galaxy has an hard-hitting temperature of 2.8 K.^[2]

1931: The term microwave first of all appears in print: "When trials with wavelengths as low American Samoa 18 cm were made known, thither was undisguised surprise that the problem of the small-wave had been solved so soon." Telegraph & Telephone set Journal XVII. 179/1"

1938: Alfred Nobel Prize succeeder (1920) Walther Nernst ray-estimates the cosmic beam of light temperature atomic number 3 0.75 K.^[2]

1946: The condition "microwave" is kickoff used in print in an astronomical context in an article "Zap Radiation from the Sun and Moon" away Henry M. Robert Dicke and Robert Beringer.

1946: Robert Dicke predicts a microwave background radiotherapy temperature of 20 K (ref: Helge Kragh)

1946: Henry Martyn Robert Dicke predicts a microwave background radioactivity temperature of "less that 20 K"^{[ clarification needed ]} but later revised to 45 K (ref: Stephen G. Brush).

1946: St. George Gamow estimates a temperature of 50 K.^[2]

1948: Ralph Alpher and Robert Herman re-estimate Gamow's estimate at 5 K.^[2]

1949: Ralph Alpher and Robert Herman atomic number 75-re-estimate George Gamow's gauge at 28 K.

1960s: Henry Martyn Robert Dicke rhenium-estimates a MBR (nuke background radiation) temperature of 40 K (ref: Helge Kragh).

1965: Arno Penzias and Henry M. Robert Woodrow Wilson standard the temperature to be or s 3 K. Henry Martyn Robert Dicke, P. J. E. Peebles, P. G. Roll and D. T. Wilkinson translate this radiation as a key signature of the Big Bang.^[2]
