. Three newly-discovered streams arcing high over the Milky Way Galaxy are remnants of cannibalized galaxies and star clusters. The streams are between 13,000 and 130,000 light-years distant from Earth and extend over much of the northern sky. Two of the newly discovered streams are almost certainly the remains of ancient star clusters. The third stream is spread over a much larger region of the sky, and is most likely the scattered remains of a dwarf galaxy. NASA/JPL-Caltech/R. Hurt (SSC)

... The search for distant objects which can be both galaxies and quasars is one of the most important problems of observational astrphysics, because it allows one to determine cosmological parameters connected with the time of appearence and evolution of stellar systems, large scale structure of the Universe. ... Radio galaxies are important objects to be studied because they are sources of infrared-optical-ultraviolet continuum, emission lines and continual radio emission. ...
