GJ 900 - a new hierarchical system with low-mass components E. Malogolovets, Yu. Balega, D. Rastegaev, K.-H. Hofmann, G. Weigelt Speckle interferometric observations made with the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences in 2000 revealed the triple nature of the nearby (d=19.3 pc) low-mass young (age about 200 Myr) star GJ 900. The configuration of the triple system allowed it to be dynamically unstable. ...

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...
