Our recent observations with the Hubble Space Telescope (August 29, 2014) led to revealing a highly isolated dwarf spheroidal galaxy KKs 3 situated at a distance of 2.12±0.07 Mpc from the Milky Way. The dSph galaxy locates on the southern sky (RA=02h24m44.4s, Dec.=-73°30'51", J2000.0) and has a stellar mass about 1/10000 of the Milky Way mass. More...

SS433 is a close binary system, one star is a supergiant, a second one is a black hole. The supergiant's matter overflows to the neighbouring black hole and floods the hole with a powerful mass flux: 6 millions of billions tons per second (that is one Earth mass for 11 days). Even a black hole cannot accept such an enormous mass flux, a supercritical accretion disk appears More...

The variability of the spectrum of the optical component of the IR-source IRAS01005+7910 was discovered for the first time in the BTA spectra [1]. Long-term monitoring of the object was carried out during 2002-2013 with a high spectral resolution (R=60000). More...

Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. More...
