Open star cluster NGC 884 in Perseus, some 7,500 light years away. The cluster consists mostly of supermassive blue stars that emit prodigious amounts of energy. They were created from the hydrogen gas cloud that the stars are themselves illuminating by a process similar to fluorescence (seen clearly as the blue haze surrounding the central stars). The reddish stars visible in this image are red giants that are tens of millions times larger than our Sun. This cluster is part of a larger "double cluster" that also includes NGC 869. Due to a pointing error, I was only able to capture NCG 884.
