We have discovered and studied the host galaxy of the “dark” gamma-ray burst GRB051008, a burst for which no optical afterglow has been detected. We studied the properties and determined the redshift of the host galaxy and analyzed its neighborhood. We perform a comparative analysis of the properties of GRB051008 and its host galaxy with the properties of other known dark gamma-ray bursts. We analyze the causes of the lack of optical afterglow in this gamma-ray burst.
