... The department was founded in late sixties by Prof. D.Ya.Martynov, who for many years was also the director of Sternberg Astronomical Institute. At present time, the head of the department is Prof. A.M.Cherepashchuk, a pupil of D.Ya.Martynov and his successor as the director of SAI. Since Prof. Martynov, the scientific activity of the department was primarily related to binary stars. ... The department consists of 15 members most of which have Ph.D. in Astrophysics. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

... What is the notion time? ... Generally speaking, it is an order of changing events, an order of constantly changing conditions of solids, Universe - being. ... The time, determined for the given longitude, is called the local time . ... A uniform system of time counting - ephemeris time is tested by observations of the Moon turning around the Earth. Fully independent from astronomic observation uniform system of the time counting is based on the concept of atomic second (see quantum watches ). ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...

... Over the next couple of days, ask a random selection of the people you meet to tell you the difference between 1/4 and 1/5. ... Show your subjects the equation e = mc2 and ask what it means. ... The equation is the most famous in science. ... Most associate it with Albert Einstein and many will say it has to do with mass and energy. A heartening number of students and teachers will even tell you the equation states that energy is equal to mass times the speed of light squared. ...
