NASA’s Hubble extends stellar tape measure 10 times farther into space

Astronomers now can precisely measure the distance of stars up to 10,000 light-years away — 10 times farther than previously possible. Astronomers have developed yet another novel way to use the 24-year-old space telescope by employing a technique called spatial scanning, which dramatically improves Hubble’s accuracy for making angular measurements. The technique, when applied to the age-old method for gauging distances called astronomical parallax, extends Hubble’s tape measure 10 times farther into space.
