A special class of type Ia supernovae that is not subject to ordinary and
additional intragalactic gray absorption and chemical evolution has been
identified. Analysis of the Hubble diagrams constructed for these supernovae
confirms the accelerated expansion of the Universe irrespective of the chemical
evolution and possible gray absorption in galaxies.
