A team of X-ray astronomers resolved the thirty-years-old puzzle of the origin of the Galactic X-ray background emission. Combining data from various space-based X-ray instruments (RXTE/PCA, INTEGRAL/IBIS, CHANDRA/ACIS, ROSAT/PSPC) and infrared instruments (COBE/DIRBE) they showed that the Galactic X-ray background predominantly consists of emission of a large number of point sources,
mostly cataclysmic variables and coronally active stars.
