... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

... BRIEF SCIENCE JUSTIFICATION: Luminous Blue Variable stars (LBVs) represent an extremely rare class of stars that define an important and poorly understood phase in the evolution of the most massive and most luminous stars. ... But there is yet another fundamental problem associated with the post-main-sequence evolution of massive stars. ... The LBV phase may now be the critical phase where most of the star's mass-loss must now occur prior to stars becoming WR stars or exploding as supernovae. ...
