... The overall globular cluster population is divided by gap in the metallicity function at [Fe/H]=-1.0 into two discrete groups with well-defined maxima at [Fe/H]=-1.60?0.03 dex, and -0.60?0.04 dex. ... Clusters with extremely blue horizontal branches occupy a spherical volume of radius ~ 9 kpc, have high rotational velocities ( V rot =77?33 km/s), have substantial and equal negative radial and vertical metallicity gradients, and are, on average, the oldest group (the old-halo subsystem). ...

... Юпитер - самая большая планета Солнечной системы. ... Поскольку Юпитер очень удален от Солонца то температура на нем довольно низкая, около -145њС. Вокруг Солнца Юпитер облетает за 12 земных лет. Интересной особенностью является то, что ось вращения Юпитера почти перпендикулярна плоскости орбиты, в результате чего на Юпитере нет смены времен года. ...

. Attached is an image of the Nova in M32. It was made under uncomfortable conditions, as our summer here in Germany makes a clear sky a rare event. To create this image, 5 images of 45 seconds each were summed. It was taken on September 12, at 21h 45m UT. Udo Zlender - Udo.Zlender@gmd.de . Back to Supernovae in NGC and IC galaxies.
