... December 8, 1999 . Moon Struck . ... Explanation: Craters produced by ancient impacts on the airless Moon have long been a familiar sight . But now observers have seen elusive optical flashes on the lunar surface - likely the fleeting result of impacting meteoroids. ... It has been estimated that the brightest flashes were made by meteoroids weighing around a tenth of a kilogram, resulting in lunar craters about one meter across. ... About APOD > . ...

... Since GCVS IV, there was no new GCVS edition. ... Main reasons for the automatic-survey new variables remaining outside the GCVS for a long time: different level of detail of the classification systems, no perfect software for automatic classification available; individual approach to each star that was always used in the GCVS cannot be applied any longer, but the experience of automatically- updated catalogs evidences for the number of errors ...
... 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. ...
... December 8, 1996 . Degas Ray Crater on Mercury . ... Explanation : Like the Earth's Moon, Mercury is scarred with craters, testifying to an intense bombardment during the early history of the Solar System. ... In the above mosaic the bright rays emanating from the 27 mile wide Degas crater almost appear to be painted on . The rays consist of light colored material blasted out during the crater's formation. Numerous smaller, younger craters are seen superposed on the Degas crater itself. ...
... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ... Brandt and Blitz (1993) published the distances and radial velocities for a total of 206 H II-regions. ... Astron. ...
