A decade later the center for radio astronomy research had gravitated to the southern Moscow region (about 75 miles south of Moscow), in Pushchino (informally called Pushchino-on-Oka). Here a new observatory, the Pushchino Radio Astronomy Observatory was developed within twenty years as part of the LPI Astro Space Center. It has become one of the largest radio astronomy observatories in Russia and in the world (2001).
