Virtual Earth-Space Telescope

Scientists have created a
 virtual Earth-space telescope system with the highest resolution of any astronomical observation ever made.

About the telescope:
Researchers created this telescope by combining the Russian RadioAstron satellite

 with the ground-based telescopes. 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. This combined system produces a virtual radio telescope more than 100,000 miles across.

What has been found out?
With this, scientists have unveiled an unusually hot quasar jet in the Milky Way.
§  Scientists have pointed out these quasar jets at a quasar called 3C 273, more than 2 billion light-years from Earth.
§  Quasars like 3C 273 propel huge jets of material outward at speeds nearly that of light. These powerful jets emit radio waves. The emission was about 100 billion degrees.
§  The observations also showed, for the first time, substructure caused by scattering of the radio waves by the tenuous interstellar material in our own Milky Way Galaxy.

What are Quasars?
Quasars are supermassive black holes at the cores of galaxies. Quasars, also called quasi-stellar radio sources, are the most energetic and distant members of a class of objects called active galactic nuclei (AGN).
§  Their spectra contain very broad emission lines, unlike any known from stars, hence the name “quasi-stellar.” Their luminosity can be 100 times greater than that of the Milky Way.
§  Quasars are believed to be powered by accretion of material into supermassive black holes in the nuclei of distant galaxies, making these luminous versions of the general class of objects known as active galaxies.
§  Quasars also emit visible light, ultraviolet rays, infrared waves, X-rays, and gamma-rays.
