... Precisely one month ago, on 11 July 2009, the last active area of the new solar cycle disappeared from the surface of the Sun.

According to Velikovsky, about 4000 years ago a giant volcano on Jupiter erupted and spewed a vast glob of debris into space, leaving the Great Red Spot behind as a permanent scar. The red hot lump ejected from Jupiter (referred to as a comet by Velikovsky) wandered into the inner Solar System, repeatedly crossing the Earth?s orbit and in fact often passing close to our helpless planet in the following millennia. ...

... 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. ...

Abstract -- Calculations are performed for the circular polarization of maser radiation from a turbulent, Keplerian disk that is intended to represent the sub-parsec disk at the nucleus of the galaxy NGC4258. ... This turbulence, along with the Keplerian velocity gradients and the blending of the three hyperfine components to form the 6 16 --5 32 masing transition of water, are key ingredients in determining the appearance of the polarized spectra that are calculated. ...
