Today radio telescopes have achieved a higher resolution and have more abilities to discern fine detail. The astronomical observation is reaching very high levels of quality. Astronomers promise to advance the understanding of quasars, supermassive black holes at the cores of galaxies.
A lot of achievements were obtained by scientists’ conjunction of the Russian RadioAstron satellite with the ground-based telescopes to produce a virtual radio telescope more than 100,000 miles across.
The RadioAstron satellite was combined with the Green Bank Telescope in West Virginia, The Very Large Array in New Mexico, the Effelsberg Telescope in Germany, and the Arecibo Observatory in Puerto Rico. Signals received by the orbiting radio telescope were transmitted to an antenna in Green Bank where they were recorded and then sent over the internet to Russia where they were combined with the data received by the ground-based radio telescopes to form the high resolution image.
