Why are Quasars so Bright? - - Russian RadioAstron Space Telescope and Arecibo Link Together to Find an Answer
Remarkable new observations derived by linking Arecibo Observatory's 305 meter dish with Russia's RadioAstron Space Radio Telescope has provided results that are causing much head scratching in radio astronomical circles. The achievable resolution from this combination of observatories is equivalent to seeing a golf ball on the Moon or a fingernail on the surface of the Earth from a spy satellite in geosynchronous orbit. What used to be a well understood explanation for the mechanism that generates intense radio signals from tiny and very distant quasar nuclei has now been tested in previously impossible ways. The results make it difficult to interpret the data in terms of conventional theories.
