With a standard <a href="/wiki/Optical_telescope" title="Optical telescope">optical telescope</a>, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive <a href="/wiki/Radio_telescope" title="Radio telescope">radio telescope</a> detects a faint background glow that is almost <a href="/wiki/Isotropic" class="mw-redirect" title="Isotropic">uniform</a> and is not associated with any star, galaxy, or other <a href="/wiki/Astronomical_object" title="Astronomical object">object</a>. This glow is strongest in the <a href="/wiki/Microwave" title="Microwave">microwave</a> region of the electromagnetic spectrum. The accidental <a href="/wiki/Discovery_of_cosmic_microwave_background_radiation" title="Discovery of cosmic microwave background radiation">discovery of the CMB</a> in 1965 by American radio astronomers <a href="/wiki/Arno_Penzias" class="mw-redirect" title="Arno Penzias">Arno Penzias</a> and <a href="/wiki/Robert_Woodrow_Wilson" title="Robert Woodrow Wilson">Robert Wilson</a> was the culmination of work initiated in the 1940s. </p><p>The CMB is landmark evidence of the <a href="/wiki/Big_Bang" title="Big Bang">Big Bang</a> <a href="/wiki/Scientific_theory" title="Scientific theory">theory</a> for the origin of the universe. In the Big Bang <a href="/wiki/Cosmological_model" class="mw-redirect" title="Cosmological model">cosmological models</a>, during the earliest periods, the universe was filled with an <a href="/wiki/Opacity_(optics)" class="mw-redirect" title="Opacity (optics)">opaque</a> fog of dense, hot <a href="/wiki/Plasma_(physics)" title="Plasma (physics)">plasma</a> of <a href="/wiki/Sub-atomic_particle" class="mw-redirect" title="Sub-atomic particle">sub-atomic particles</a>. As the universe expanded, this plasma cooled to the point where protons and electrons combined to form neutral atoms of mostly hydrogen. Unlike the plasma, these atoms could not scatter thermal radiation by <a href="/wiki/Thomson_scattering" title="Thomson scattering">Thomson scattering</a>, and so the universe became transparent. Known as the <a href="/wiki/Recombination_(cosmology)" title="Recombination (cosmology)">recombination</a> epoch, this <a href="/wiki/Decoupling_(cosmology)" title="Decoupling (cosmology)">decoupling</a> event released <a href="/wiki/Photons" class="mw-redirect" title="Photons">photons</a> to travel freely through space. However, the photons have grown less <a href="/wiki/Photon_energy" title="Photon energy">energetic</a> due to the <a href="/wiki/Cosmological_redshift" class="mw-redirect" title="Cosmological redshift">cosmological redshift</a> associated with the <a href="/wiki/Expansion_of_the_universe" title="Expansion of the universe">expansion of the universe</a>. The <i>surface of last scattering</i> refers to a shell at the right distance in space so photons are now received that were originally emitted at the time of decoupling. </p><p>The CMB is not completely smooth and uniform, showing a faint <a href="/wiki/Anisotropy" title="Anisotropy">anisotropy</a> that can be mapped by sensitive detectors. Ground and space-based experiments such as <a href="/wiki/Cosmic_Background_Explorer" title="Cosmic Background Explorer">COBE</a>, <a href="/wiki/Wilkinson_Microwave_Anisotropy_Probe" title="Wilkinson Microwave Anisotropy Probe">WMAP</a> and <a href="/wiki/Planck_(spacecraft)" title="Planck (spacecraft)">Planck</a> have been used to measure these temperature inhomogeneities. The anisotropy structure is determined by various interactions of matter and photons up to the point of decoupling, which results in a characteristic lumpy pattern that varies with angular scale. The <a href="/wiki/Distribution_(mathematics)" title="Distribution (mathematics)">distribution</a> of the anisotropy across the sky has <a href="/wiki/Frequency" title="Frequency">frequency</a> components that can be represented by a <a href="/wiki/Power_spectrum" class="mw-redirect" title="Power spectrum">power spectrum</a> displaying a sequence of peaks and valleys. The peak values of this spectrum hold important information about the physical properties of the early universe: the first peak determines the overall <a href="/wiki/Curvature_of_the_universe" class="mw-redirect" title="Curvature of the universe">curvature of the universe</a>, while the second and third peak detail the density of normal matter and so-called <a href="/wiki/Dark_matter" title="Dark matter">dark matter</a>, respectively. Extracting fine details from the CMB data can be challenging, since the emission has undergone modification by foreground features such as <a href="/wiki/Galaxy_cluster" title="Galaxy cluster">galaxy clusters</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Features">Features</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_microwave_background&amp;action=edit&amp;section=1" title="Edit section: Features"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Cmbr.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Cmbr.svg/300px-Cmbr.svg.png" decoding="async" width="300" height="240" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Cmbr.svg/450px-Cmbr.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Cmbr.svg/600px-Cmbr.svg.png 2x" data-file-width="600" data-file-height="480" /></a><figcaption>Graph of cosmic microwave background spectrum around its peak in the <a href="/wiki/Microwave" title="Microwave">microwave</a> frequency range,<sup id="cite_ref-Komatsu2022Review_1-0" class="reference"><a href="#cite_note-Komatsu2022Review-1"><span class="cite-bracket">&#91;</span>1<span class="cite-bracket">&#93;</span></a></sup> as measured by the FIRAS instrument on the <a href="/wiki/Cosmic_Background_Explorer" title="Cosmic Background Explorer">COBE</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup> While vastly exaggerated "<a href="/wiki/Standard_error_of_estimation" class="mw-redirect" title="Standard error of estimation">error bars</a>" were included here to show the measured data points, the true error bars are too small to be seen even in an enlarged image, and it is impossible to distinguish the observed data from the <a href="/wiki/Blackbody" class="mw-redirect" title="Blackbody">blackbody</a> spectrum for 2.725&#160;<a href="/wiki/Kelvin" title="Kelvin">K</a>.</figcaption></figure> <p>The cosmic microwave background radiation is an emission of uniform <a href="/wiki/Black_body" title="Black body">black body</a> <a href="/wiki/Thermal_energy" title="Thermal energy">thermal energy</a> coming from all directions.

Alternative explanations included energy from within the solar system, from galaxies, from intergalactic plasma and from multiple extragalactic radio sources. Two requirements would show that the microwave radiation was truly "cosmic". First, the intensity vs frequency or spectrum needed to be shown to match a thermal or blackbody source. This was accomplished by 1968 in a series of measurements of the radiation temperature at higher and lower wavelengths. Second, the radiation needed be shown to be isotropic, the same from all directions. This was also accomplished by 1970, demonstrating that this radiation was truly cosmic in origin.<sup id="cite_ref-PartridgeReview_27-0" class="reference"><a href="#cite_note-PartridgeReview-27"><span class="cite-bracket">&#91;</span>27<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Progress_on_theory">Progress on theory</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_microwave_background&amp;action=edit&amp;section=6" title="Edit section: Progress on theory"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In the 1970s numerous studies showed that tiny deviations from isotropy in the CMB could result from events in the early universe.<sup id="cite_ref-PartridgeReview_27-1" class="reference"><a href="#cite_note-PartridgeReview-27"><span class="cite-bracket">&#91;</span>27<span class="cite-bracket">&#93;</span></a></sup><sup class="reference nowrap"><span title="Page / location: 8.5.1">&#58;&#8202;8.5.1&#8202;</span></sup> Harrison,<sup id="cite_ref-28" class="reference"><a href="#cite_note-28"><span class="cite-bracket">&#91;</span>28<span class="cite-bracket">&#93;</span></a></sup> Peebles and Yu,<sup id="cite_ref-29" class="reference"><a href="#cite_note-29"><span class="cite-bracket">&#91;</span>29<span class="cite-bracket">&#93;</span></a></sup> and Zel'dovich<sup id="cite_ref-30" class="reference"><a href="#cite_note-30"><span class="cite-bracket">&#91;</span>30<span class="cite-bracket">&#93;</span></a></sup> realized that the early universe would require quantum inhomogeneities that would result in temperature anisotropy at the level of 10<sup>−4</sup> or 10<sup>−5</sup>.<sup id="cite_ref-PartridgeReview_27-2" class="reference"><a href="#cite_note-PartridgeReview-27"><span class="cite-bracket">&#91;</span>27<span class="cite-bracket">&#93;</span></a></sup><sup class="reference nowrap"><span title="Page / location: 8.5.3.2">&#58;&#8202;8.5.3.2&#8202;</span></sup> <a href="/wiki/Rashid_Sunyaev" title="Rashid Sunyaev">Rashid Sunyaev</a>, using the alternative name <i>relic radiation</i>, calculated the observable imprint that these inhomogeneities would have on the cosmic microwave background.<sup id="cite_ref-31" class="reference"><a href="#cite_note-31"><span class="cite-bracket">&#91;</span>31<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="COBE">COBE</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Cosmic_microwave_background&amp;action=edit&amp;section=7" title="Edit section: COBE"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>After a lull in the 1970s caused in part by the many experimental difficulties in measuring CMB at high precision,<sup id="cite_ref-PartridgeReview_27-3" class="reference"><a href="#cite_note-PartridgeReview-27"><span class="cite-bracket">&#91;</span>27<span class="cite-bracket">&#93;</span></a></sup><sup class="reference nowrap"><span title="Page / location: 8.5.1">&#58;&#8202;8.5.1&#8202;</span></sup> increasingly stringent limits on the anisotropy of the cosmic microwave background were set by ground-based experiments during the 1980s. <a href="/wiki/RELIKT-1" title="RELIKT-1">RELIKT-1</a>, a Soviet cosmic microwave background anisotropy experiment on board the Prognoz 9 satellite (launched 1 July 1983), gave the first upper limits on the large-scale anisotropy.<sup id="cite_ref-PartridgeReview_27-4" class="reference"><a href="#cite_note-PartridgeReview-27"><span class="cite-bracket">&#91;</span>27<span class="cite-bracket">&#93;</span></a></sup><sup class="reference nowrap"><span title="Page / location: 8.5.3.2">&#58;&#8202;8.5.3.2&#8202;</span></sup> </p><p>The other key event in the 1980s was the proposal by <a href="/wiki/Alan_Guth" title="Alan Guth">Alan Guth</a> for <a href="/wiki/Cosmic_inflation" title="Cosmic inflation">cosmic inflation</a>.

The acoustic oscillations arise because of a conflict in the <a href="/wiki/Photon" title="Photon">photon</a>–<a href="/wiki/Baryon" title="Baryon">baryon</a> plasma in the early universe. The pressure of the photons tends to erase anisotropies, whereas the gravitational attraction of the baryons, moving at speeds much slower than light, makes them tend to collapse to form overdensities. These two effects compete to create acoustic oscillations, which give the microwave background its characteristic peak structure. The peaks correspond, roughly, to resonances in which the photons decouple when a particular mode is at its peak amplitude. </p><p>The peaks contain interesting physical signatures. The angular scale of the first peak determines the <a href="/wiki/Shape_of_the_universe" title="Shape of the universe">curvature of the universe</a> (but not the <a href="/wiki/Topology" title="Topology">topology</a> of the universe).

The fine-scale structure is superimposed on the raw CMBR data but is too small to be seen at the scale of the raw data. The most prominent of the foreground effects is the dipole anisotropy caused by the Sun's motion relative to the CMBR background. The dipole anisotropy and others due to Earth's annual motion relative to the Sun and numerous microwave sources in the galactic plane and elsewhere must be subtracted out to reveal the extremely tiny variations characterizing the fine-scale structure of the CMBR background. The detailed analysis of CMBR data to produce maps, an angular power spectrum, and ultimately cosmological parameters is a complicated, computationally difficult problem. </p><p>In practice it is hard to take the effects of noise and foreground sources into account.

However, they did not refer to such a background, but only to 'radiation from cosmic matter'. Also, this work was unrelated to cosmology and is only mentioned because it suggests that by 1950, detection of the background radiation might have been technically possible, and also because of Dicke's later role in the discovery".
