... 2001 January 8 . Help NASA Classify Martian Craters . Credit: Sonie Lau , NASA Ames . Explanation: The large Martian crater above just left of center: is this a fresh crater, a degraded crater, or a ghost crater? ... Additionally, there are so many craters on Mars that NASA just doesn't have enough people to classify them all! Therefore, you can help humanity's understanding of the surface of Mars by volunteering to classify craters . ... About APOD | ... NASA Technical Rep.: ...

... 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 ...

... 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. ...

... 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. ...
