CH Cyg is one of the most fascinating as well as the brightest and closest symbiotic stars. It's composed of an M7 giant and a hot companion, most likely an accreting white dwarf. More...

A bright extended nebulosity around a lenticular galaxy NGC 4460 was discovered by Igor Karachentsev and Serafim Kaisin (2008, A&A, 479, 603) during the recent H survey of nearby galaxies on the SAO RAS 6-m telescope. More...

The brightest of all GRBs known to date, GRB080319B, the "Naked-Eye Burst", has been observed by our colleagues who acquired its detailed optical light curve during the stage of gamma emission. More...

Dwarf galaxy DDO 68 is the closest to us galaxy (D=10Mpc) with the lowest metal content known to date. In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10⁵ Sun's luminocities in visible light) was found. More...

New observations of the RC J0311+0507 radio source using the MERLIN radio interferometer (UK) and the 6-m optical telescope, have added new strokes to the "portrait" of this unusual object, - one of the most powerful and distant radio galaxies (z=4.51), and raised new questions about the origin of the first galaxies in the early Universe.
