Main actors in astronomy research in the country  There are 7 Research Institutes in the structure of the National Academy of Sciences of Ukraine (NAS of Ukraine), 2 Research Institutes in the structure of the Ministry of Education and Science, Youth and Sport of Ukraine (MESYS of Ukraine); 15 astronomical observatories and Departments in the structure of the Universities of the MESYS of Ukraine; 1 Private Astronomical Observatory play a main role in the development and teaching Astronomy in Ukraine.
The XPM Catalog  Absolute proper motions of 280 million stars distributed all over the sky without gaps in the magnitude range 10m < V <20m on the basis of combined data from 2MASS and USNO-A2.0 catalogues.
MAO NASU Plate Archive   Digital archive of MAO NAS of Ukraine (GPA) comprises data of about 26 thousands of direct photographic plates, obtained with 14 instruments in 9 observational sites, and more than 2000 digital images of different resolution available via GPA search pages.
Mykolaiv AO Plate Archive   Digital archive of Mykolaiv Aastronomical Observatory (MykAO) includes astronomical data obtained during observations with photo plates and CCD frames. The digitization of the archive is near its completion. Digitized images are available via a web browser and Aladin.
AO LNU Plate Archive   Astronomical Observatory of Lviv National University (AO LNU) is the owner of valuable archive that stores approximately 8 000 of photographic plates from 1939, including nearly 6 000 direct images of the northern sky. The archive is partly digitized and images are available via the joint search pages of AO LNU and MAO NASU.
IRA UTR-2 catalogue of RS   The very-low frequency sky survey of discrete sources has been obtained in the Institute of Radio Astronomy of the Ukrainian National Academy of Sciences (Kharkov, Ukraine) with the UTR-2 radio telescope at a number of the lowest frequencies used in contemporary radio astronomy within the range from 10 to 25 MHz.
Mykolaiv AO stellar catalogues   27 astrometric stellar catalogues of Mykolaiv Aastronomical Observatory (MykAO) in VOTable format are available for downloading
AO KNU Historic Plate Archive   AO KNU glass collection contains about 20 thousand photographic plates. Historical part of the archive was received during 1898-1946 and now is being digitized.

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...
GRID-based Virtual Observatory VIRGO.UA 
VO VIRGO.UA for cosmology and astrophysics is a segment of VO «Infrastructure»- a virtual organization, which deals with ensuring the provision of standards for Grid Services for virtual organizations, to ensure reliability functioning of the Ukrainian power grid, Grid training for users and administrators of the Grid sites, as well as the creation of technical conditions UNG for entry into the international grid community...
WDC-Ukraine is a part of World Data Center System of the International Council of Science (ICSU). Among the basic tasks of WDC-Ukraine there is collection, handling and storage of science data and giving access to it for usage both in science research and study process. That include contemporary tutoring technologies and resources of e-libraries and archives; remote access to own information resources for the wide circle of scientists from the universities and science institutions of Ukraine...
US VAO Data Discovery Portal 
Find datasets from thousands of astronomical collections known to the VO and over wide areas of the sky. This includes important collections from archives around the world. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
US VAO Cross-Comparison Tool 
Perform fast positional cross-matches between an input table of up to 1 million sources and common astronomical source catalogs, such as 2MASS, SDSS DR7 and USNO-B. Feedback on your experience with the tool is appreciated -- please send your comments, suggestions, and questions to the VAO Help Desk.
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.

 Choliy Vasiliy Yaroslavovich 

General data:

Born: 20.03.1963

Place of birth: Rohatyn city, Ivano-Frankivsk region, Ukrainian SSR

Studied in: T. G. Shevchenko Kyiv Order of Lenin State University (since 1999 Taras Shevchenko Kyiv National University) (1980-1985);

Key interests: geodynamics, Earth's rotation, geophysics. PhD Thesis: Comparing and combining different series of definitions of the Earth rotation parameters (1991 Main Astronomical Observatory of the National Academy of Sciences of Ukraine); ScD Thesis: Models of global geodynamics and their testing according to satellite observations (2021 Main Astronomical Observatory of the National Academy of Sciences of Ukraine);


He was born on March 20, 1963 in Rogatin city of the Ivano-Frankivsk region of the Ukrainian SSR.

During 1980-1985 he was a student of the Department of Astronomy at the Faculty of Physics of the T. G. Shevchenko Kiev Order of Lenin State University.

In the 80 years of the XX century, together with Yatskiv Ya. S., they compared a variety of coordinates of the pole of the Earth derived from the laser location of the LAGEOS in the main company of the MERIT project. The estimates of the variance of the coordinates of the pole, on which various variants of the combined series of these coordinates are constructed, and estimation of their accuracy are found. The results can be used for constructing free rows of Earth rotation parameters.

In 1991, he defended his Ph.D. thesis "Comparison and integration of various rows of definitions of Earth's rotation parameters" at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine and received his Ph.D. degree in Physics and Mathematics.

Since 2008 he has been working in the Ukrainian network of stations of space geodesy and geodynamics, led by the laboratory "Ukrainian Center for determining the parameters of the Earth's rotation", which was part of the astrometry and space geodynamics department of the Main Astronomical Observatory of the National Academy of Sciences of Ukraine until 2016. During 2011-2015 he was the executor of the duty Head of Laboratory. He is a lecturer of the Department of Astronomy and Space Physics of the Faculty of Physics of the Taras Shevchenko Kyiv National University.

In mid-September 2021 he defended at the Main Astronomical Observatory of the National Academy of Sciences of Ukraine his dissertation for the degree of Doctor of Physical and Mathematical Sciences "Models of global geodynamics and their testing according to satellite observations" in the specialty 05.07.12 - remote aerospace research.
