... Advises . Contact Advises . As an advise for amateurs we would like to underline: if it's possible, try to observe 3 asteroid positions per night and do not neglect to observe the Numbered Minor Planets in your telescope field of view as a "by product" of your observational programs. ... We think such estimations ought to be produced every morning after CCD observations of the moving celestial objects by observer himself. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... Piotrovich Main Astronomical Observatory, Pulkovo, St. Petersburg, Russia Received May 24, 2006; in final form, July 7, 2006 Abstract--We have used two astrometric methods developed at the Main Astronomical Observatory of the Russian Academy of Sciences--the method of apparent-motion parameters (AMP) and a direct geometrical method (DGM)--to derive the orbit of the star S2 around the Galactic center, and thereby the mass of the supermassive black hole at the Galactic center. ... Relative positions. ...

Главная Проекты Mars Exploration Rover . ... With far greater mobility than the 1997 Mars Pathfinder rover, these robotic explorers will be able to trek up to 100 meters (about 110 yards) across the surface in a Martian day. ... The rovers will be identical to each other, but will land at different regions of Mars. ... Where Pathfinder had scientific instruments on both the lander and the small Sojourner rover, these larger rovers will carry all their instruments with them. ...
