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.

 Diabay Eric (Ernest) Apushevich 

General data:

03.08.1931 - 11.11.1983

Place of birth: Kazan city, Tatar Autonomous Soviet Socialist Republic

Studied in: V. I. Ulyanov-Lenin Kazan State University (since 2010 'Kazan (Volga region) Federal University') (1949-1954);

Key interests: astrophysics, physics of extragalactics, extragalactic astronomy, AGNs, non-stationary stars. PhD Thesis: Some questions of evolution of interstellar environment (1958 ); ScD Thesis: Problems of comet-like nebulae (1970 );


He was born on August 3, 1931 in Kazan city Tatar Autonomous Soviet Socialist Republic.

During 1949-1954 he was a student of the Faculty of Physics and Mathematics of V. I. Ulyanov-Lenin Kazan State University. He graduated from the Department of Astronomy.

Since 1954 to 1958 he was a graduate student of the Department of Astrophysics, Faculty of Mechanics and Mathematics of M. V. Lomonosov Moscow State University.

In 1958 he defended his dissertation "Some questions of the evolution of the interstellar environment".

During 1958-1961 he worked as a junior researcher at the P. K. Sternberg State Astronomical Institute of M. V. Lomonosov Moscow State University.

During 1961-1977 he was the first director of the Southern Base of the P. K. Sternberg State Astronomical Institute of the M. V. Lomonosov Moscow State University (Crimean Astrotrophysical Observatory), which had several telescopes, including a 125-centimeter refractor. (ZTE) and two 60-centimeter telescopes of the German company "Zeiss", the installation and commissioning of which he directed since 1960.

During 1977-1983 he was a professor at the Department of Astrophysics and Stellar Astronomy of Faculty of Physics in M. V. Lomonosov Moscow State University. He lectured on the interstellar environment to students of the astronomical department of the physics department of the university. Of particular interest was the unique course "Theory of Dimensionality in Astrophysics".

Since 1964 he was a member of the International Astronomical Union.

In the 1960s, he dealt with the problem of star chains.

Beginning in 1963, he participated together with V.F. Yesipov and M. A. Arakelyan in the spectral observations of about 1,000 galaxies to search for galaxies with active nuclei. As a result, 50 new Seyfert-type galaxies were discovered, making up a significant portion of currently known galaxies of this type. Measurements of radial velocities, luminosities of galaxy nuclei and analysis of physical conditions in them were performed. In addition to galaxies with active nuclei, EA Dibay and co-authors studied the spectra of a number of quasars and some nonstationary stars, including T-Taurus stars, galactic new stars, and supernovae in other galaxies.

In 1964 he and VI Detailed spectral observations of Seifert galaxies with the help of a 125-centimeter reflector at the Crimean station of the P. K. Sternberg State Astronomical Institute began to penetrate. They proposed the term "broad emission region" for galaxies with active nuclei. In 1965 he together with the Crimean astronomer VN Pronik built a photoionization 2-zone model of the glow region of emission lines: BLR (broad line region) and NLR (narrow line region) and evaluated the main parameters of these regions.

In 1970 he defended his doctoral dissertation "Problems of comet-like nebulae."

EA Dibay, VI Pronik, KK Chuvaev and VM Luty in the 70s of the XX century made a great contribution to the study of the central regions of the Seifert Galaxy in the optical range. In particular, E.A. Dibay and VI Pronik proposed an "empirical model of active nuclei" based on the analysis of their spectra and the assumption of photoionization of gas clouds by a continuous non-thermal continuum from the active nucleus. In 1984, together with Luty V. M., he established some relationship between the characteristic times of short flashes and the masses of compact massive objects (CMOs): logΔt ~ 3 + 0.43 · logM KMO .

Together with M. A. Arakelyan, V. L. Afanasyev, V. F. Yesipov, I. M. Kopylov, A. T. Ghazaryan,

A. Burenkov, V. Sargent, D. Widman, and J. Mazzarell studied the spectra of Markarian galaxies on the 1.2-meter telescope of the Crimean Southern Base of the P. K. Sternberg State Astronomical Institute of the M.V. Lomonosov Moscow State University, on the 2.6-meter telescope of the Crimean Astrophysical Observatory and on other telescopes with slit spectrographs and photoelectric sensitive equipment. As a result, among 1,512 galaxies in the Markarian catalog, they identified about 160 (181) Seyfert galaxies, 13 QSOs, and other active galaxies.

Total EA Dibay has published more than 100 scientific papers on extragalactic astronomy and interstellar physics.

He was a member of the editorial boards of the letters "Letters to the Astronomical Journal" and "Astronomical Journal", in the latter he was a scientific secretary.

He died on November 11, 1983 in Moscow.

Name E.A. Dibay was assigned to the Crimean Laboratory of the P. K. Sternberg State Astronomical Institute of the M. V. Lomonosov Moscow State University, and the small planet №2385 was named Dibay
