The Role of Data Science in Astronomy and Interstellar Exploration 
Space has always been a fascinating frontier for humans. From the first satellite, Sputnik 1, in 1957, to the amazing Mars rovers, our adventures in space show our love for discovery, creativity, and courage. Exploring space is a big dream, always pushing us to learn more and go further. Nowadays, data science is making a meaningful contribution to space technology. It's changing how we think about space. Being able to gather, understand, and use lots of data has helped us get to know the universe better and has changed how we explore and move through space...

VOPlot v1.8 Beta 
VOPlot v1.8Beta includes many enhancements and bug fixes. To name a few v1.8Beta supports multi-grid plots for 2D Scatter-Plot which allows the user to have multiple plots having grid size from 1x1 to 3x3 in a single window. Paginated view is added to see data in tabular format which allows user to navigate systematically. Provision to label Lat/Long lines is also added. Users can now plot a cumulative histogram for all histogram types. VOPlot 1.8Beta shows the metadata of a FITS file instantaneously while the actual loading happens in background. VOPlot v1.8Beta also provides better handling of "faulty data" while parsing an ASCII file.

The scientific interests of the theoretical physicist cover a wide range of problems. Among them are the problems of philosophy of science, astrophysics and geophysics, cosmology, statistical physics, quantum theory, in particular the theory of quantum liquids, the theory of phase transitions, physics of disordered systems.

His most significant works in quantum theory include his work on the theory of superfluidity, the phenomenon that was discovered in 1938 by Peter Kapitsa, the phenomenon observed in liquid helium at temperatures close to absolute zero and in which the main role is played by quantum effects. With the help of his new microscopic theory of Bose liquids, created by him in the 90's, for the first time from the first principles, the transition due to Bose-Einstein condensation has been described, the main mechanisms of the influence of interatomic interaction on this phenomenon and the concrete manifestations of its connection with λ-transition. A peculiar culmination of studies of the phenomenon of superfluidity was the calculation of the critical temperature of the Bose-Einstein condensation and the thermodynamic functions of the Bose condensate.

Using the method of two-time Green's functions, he built a microscopic theory of disordered systems, which allows the only way to describe the basic manifestations of structural disorder and their dependence on external influences (fields, pressure, temperature, etc.). His works on critical phenomena and the development of microscopic methods statistical descriptions, cause an interest in the scientific world.

Of special importance in the field of astrophysics is its microscopic theory of stellar spectra, which allowed to predict new physical effects associated with the mechanism of formation of frahungfer lines.
