Astronomers have succeeded in precisely determining the astronomical yardstick for the Galaxy based upon precise distance measurements from advanced radio telescopes. The new findings are that the distance from the sun to the Galactic center is 26,100 light-years, and that the Galactic rotation velocity in the solar system is 240km/s.
