Massive Radio Telescope Starts Observing the Skies


New submitter cyachallenge writes with this excerpt from New Scientist: "RadioAstron, effectively the largest radio telescope ever built, is up and running. The telescope's main component, a 10-metre radio dish aboard the spacecraft Spectr-R, launched in July to an oblong orbit that extends between 10,000 and more than 300,000 kilometres from Earth. By coordinating observations with radio telescopes on Earth in a technique called interferometry, the telescope can make observations as sharp as a single dish spanning the entire distance between the two farthest dishes. When Spectr-R is at its farthest from Earth, the system acts like one enormous telescope about 30 times as wide as our planet, boasting about 10,000 times the resolution of the Hubble Space Telescope."
