Haffner 18 Open star cluster Haffner 18. ESO; Four open clusters have been known from earliest times: the Pleiades and Hyades in the constellation Taurus, Praesepe (the Beehive) in the constellation Cancer, and Coma Berenices.The Pleiades was so important to some early peoples that its rising at sunset determined the start of their year.

RR Lyrae Distance RR Lyrae stars are pulsating stars like Cepheids, but they are low mass stars with short periods (less than a day). download Mean distance of stars whose radial velocities, proper motions and parallaxes have been determined audiobook Recent photometric results have identified a new population among globular cluster stars. This population, referred to as the ``extended P1'', has been suggested to be the manifestation of a new abundance pattern where the initial mass fraction of He changes among cluster stars that share the same CNO values.
