December 2006 Astronotes 1 Hubble sees Red! ... Hubble did the maths and discovered that M31 was very distant indeed (2.2 million light years away is the accepted figure today), so far in fact that it must be a galaxy in its own right. ... M31 Andromeda Galaxy A Hubble Space Telescope view of the galaxy's core is now called Hubble's Law, and it made his name. ... If you measure the redshift of a galaxy, you will know its velocity, and by Hubble's Law, you will automatically know its distance away. ...

. Authors . Problem . Method . Advises . Contact Analysis of an accuracy of CCD asteroid observations carried out by professional and amateur astronomers . An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400
