Català: L'espectre monopolar de la radiació de fons còsmica de microones utilitzant el conjunt de dades original de l'equip FIRAS, disponible a http://lambda.gsfc.nasa.gov/product/cobe/firas_monopole_get.cfm. L'eix vertical "MJy/sr" correspon 106 jansky per estereoradian, on hi ha un jansky 10-26 Watts per metre quadrat per Hertz. L'eix horitzontal ("1/cm") correspon al recíproc de la longitud d'ona de les microones (en cm), que és proporcional a la freqüència de les microones. Les barres d'error són massa petites per mostrar-les en una pantalla d'ordinador, però es van incloure barres d'error molt exagerades per mostrar els punts de dades mesurats. Fet amb GNUPlot.
Comentari de la NASA sobre la imatge original: "Espectre de fons còsmic de microones (CMB) representat en ones per centímetre en funció de la intensitat. La corba sòlida mostra la intensitat esperada d'un espectre de cos negre de temperatura única, tal com prediu la teoria del Big Bang calent. Un cos negre és un cos hipotètic que absorbeix tota la radiació electromagnètica que cau sobre ell i no reflecteix cap. Les dades FIRAS es van prendre a 34 posicions igualment espaciades al llarg d'aquesta corba. Les dades FIRAS coincideixen amb la corba tan exactament, amb incerteses d'error inferiors a l'amplada de la corba del cos negre, que és impossible distingir les dades de la corba teòrica. Aquestes mesures precises de CMB mostren que el 99,97% de l'energia radiant de l'Univers es va alliberar durant el primer any després del propi Big Bang. Totes les teories que intenten explicar l'origen de l'estructura a gran escala que es veu avui a l'Univers s'han d'ajustar ara a les limitacions imposades per aquestes mesures. Els resultats mostren que la radiació coincideix amb les prediccions de la teoria del Big Bang en un grau extraordinari. Vegeu Mather et al. 1994, Astrophysical Journal, 420, 439, "The Cosmic Microwave Background Spectrum from the Full COBE FIRAS Data Sets", Wright et al. 1994, Astrophysical Journal, 420, 450, "Interpretation of the COBE FIRAS CMBR Spectrum", i Fixsen et al. 1996, Astrophysical Journal, 473, 576, "The Cosmic Microwave Background Spectrum from the Full COBE FIRAS Data Sets" per obtenir més informació." English: The monopole spectrum of the Cosmic Microwave Background Radiation using the original data set by the FIRAS team, available at http://lambda.gsfc.nasa.gov/product/cobe/firas_monopole_get.cfm. The vertical axis "MJy/sr" corresponds to 106 jansky per steradian, where a jansky is 10-26 Watts per square-meter per Hertz. The horizontal axis ("1/cm") corresponds to the reciprocal of the microwave wavelength (in cm), which is proportional to the microwave frequency. The error bars are too small to be displayed by a computer screen, but vastly exaggerated error bars were included to show the measured data points. Made with GNUPlot.
NASA's comment on the original picture: "Cosmic Microwave Background (CMB) spectrum plotted in waves per centimeter vs. intensity. The solid curve shows the expected intensity from a single temperature blackbody spectrum, as predicted by the hot Big Bang theory. A blackbody is a hypothetical body that absorbs all electromagnetic radiation falling on it and reflects none whatsoever. The FIRAS data were taken at 34 positions equally spaced along this curve. The FIRAS data match the curve so exactly, with error uncertainties less than the width of the blackbody curve, that it is impossible to distinguish the data from the theoretical curve. These precise CMB measurements show that 99.97% of the radiant energy of the Universe was released within the first year after the Big Bang itself. All theories that attempt to explain the origin of large scale structure seen in the Universe today must now conform to the constraints imposed by these measurements. The results show that the radiation matches the predictions of the hot Big Bang theory to an extraordinary degree. See Mather et al. 1994, Astrophysical Journal, 420, 439, "Measurement of the Cosmic Microwave Background Spectrum by the COBE FIRAS Instrument,"Wright et al. 1994, Astrophysical Journal, 420, 450,"Interpretation of the COBE FIRAS CMBR Spectrum," and Fixsen et al. 1996, Astrophysical Journal, 473, 576,"The Cosmic Microwave Background Spectrum from the Full COBE FIRAS Data Sets" for details." Deutsch: Das Monopolspektrum der kosmischen Hintergrundstrahlung. Es wurden die Originaldaten des FIRAS Teams zugrundegelegt, zu finden hier: http://lambda.gsfc.nasa.gov/product/cobe/firas_monopole_get.cfm. Die echten Fehlerbalken sind zu klein, um von einem Bildschirm dargestellt werden zu können, wesentlich größere Fehlerbalken wurden dargestellt, um die gemessenen Datenpunkte sichtbar zu machen. Erstellt mit GNUPlot.
