Image of rapidly varying objects such as BL Lacerta 0716 714 obtained from observations RadioAstron with the European VLBI Network at 6.2 cm wavelength map restored with a circular pattern of 0.5 milliarcseconds. Contours made in terms of equal intensity with the increase for each subsequent half, from 0.25 mJy / beam, the peak - 0.43 Jan / beam.
October 9 Astro Space Center FIAN published new results obtained in the course of the early scientific program "Radioastron." International group that has been researching the nuclei of active galaxies have obtained a radio active galaxies 714 0716.
Russia’s RadioAstron space observatory
The first image of the rapidly active galaxy 0716 714 was obtained at a wavelength of 6.2 cm on the results of observations of ground-space interferometer "RadioAstron" (space radio telescope "Spektr-R" in conjunction with the European VLBI Network). The analysis used data obtained during the observation session lasting more than 24 hours, in which about a dozen of the largest land-based radio telescopes.
Image of an object of type BL Lacerta 0716 714 was obtained from observations conducted on March 14-15, 2012, in the early part of the scientific program RadioAstron in active galactic nuclei. In addition to producing visible able to measure the parameters of the radio galaxy nucleus, the width of the jet at the base, which is about 70 microseconds of arc or 0.3 parsecs, and other astrophysical data.

According to scientists, radio-interferometry - complicated experimental field of study that requires a long time to process the data. Therefore, from time to experiment before the publication of the results can range from one year to several years.
September 27, 2011 space radio telescope "Spektr-R" (developed by NPO. Lavochkin) recorded the "first light" from the supernova remnant Cassiopeia A. In the course of this year, ground-space radio interferometer "Radioastron" proved its stability and performance in all four wavelength bands - 92, 18, 6 and 1.3 cm.
