Visit my website at [ Ссылка ] - astrometry is the science of measuring the position, distance and movement of the stars. This science will take a giant leap forward with the launch of ESA's new space telescope, Gaia. This new tool will make it possible to measure a billion stars of our Milky Way.
Please rate and comment, thanks!
