... Here is an image a supernova in NGC4704. The image taken at 6.4.1998 at 21.08 UT, CCD ST-7, 840s. Track and Accumulate exposure (21x40s), no filter, dark and flat corrected, temp -20c, telescope used 152/2063 refractor. Image were taken at the center of our city, Jyvaskyla. ... Dark lines in image are error of track and accumulate process and even dark and flat field were corrected, there still remain some noise. ... Back to Supernovae in NGC and IC galaxies. ...

... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...
