Within the Bose-Einstein statistics it is shown that the blackbody radiationcontains coalescent photons along with single photons. Coalescent photons werefirst observed in the famous Hong-Ou-Mandel experiment of 1987. For the sake ofconvenience, $N$ coalescent photons are referred to as the $N$-photon cluster.In this work, statistics of photon clusters and probability that a photoncluster contains $N$ photons are found versus radiation frequency andtemperature. Spectra of photon-cluster radiation are calculated as functions ofblackbody temperature for different cluster ranks. Derivation of the Planck'sradiation law is discussed in view of the existence of photon clusters inblackbody radiation.
