Biography:
He was born in 1941, according to other sources, on June 30, 1940 in Novorossiysk city of Krasnodar Krai of Russian SSR.
During 1958-1964 he was a student of the Astronomical Department of the Physics Department of the M. V. Lomonosov Moscow State University.
Since 1964 he studied at the graduate school under the guidance of Professor B. V. Kukarkin at the P. K. Sternberg State Astronomical Institute.
Employee of the Crimean Astrophysical Observatory (Southern Station of the P. K. Sternberg State Astronomical Institute in the Naukoviy village of the Crimea in 1967. He having passed positions from junior researcher to chief researcher.
In 1972 he defended his dissertation on "Photometric features of Seyfert galaxies and the optical variability of their nuclei." In 1977 he defended his doctoral dissertation on "Optical variability of X-ray binary and galaxy nuclei."
Together with O. S. Sharov and V. F. Esipov conducted an in-depth photometric study of the Andromeda Nebula and globular clusters in this galaxy. In 1967 at the Southern Station of the P. K. Sternberg State Astronomical Institute he made an phototometer with photon count with UBV filters.
With the help of this photometer V. M. Ljutiy studied SyG and quasars, and highlighted the abnormally blue color of the inner regions, noted the two-component (fast - several days and slow - years) nature of their variability, pointed to the presence of a large share of thermal components in SyG radiation. Together with A. M. Cherepashchuk and H. F. Khaliulin made in 1970 a narrowband photometer with a wedge interference filter and for the first time, together with A. M. Cherepashchuk, found a delay of several days changes in the flow in the emission line in relation to the change in the SyG continuum. Their interpretation of this effect - photoionization and light echo - in 1978 was fully confirmed by observations with IUE.
E. A. Dibay, V. I. Pronik, K. K. Chuvaev he central regions of the Seifert Galaxy in the optical range. In particular, in 1972 he and A. M. Cherepashchuk developed a method of "echo mapping" to estimate distances, in 1984 he and E. A. Dibay established some relationship between the characteristic times of short flashes and the masses of compact massive objects. (KMO): logΔt ~3+0.43·logMKMO. Since 1968, observing the variability of the nuclei of Seifert Galaxies on a very sensitive photometer to the nearest 0.m01, he concluded that in some of them (NGC 4151, NGC 7469, NGC 3516 and quasar 3C 273) there is a period of ~160 minutes. (Surprisingly, the same period was observed by A. B. Severny and V. A. Kotov in the change of velocities of radiation lines in the central region of the Sun). this "mysterious" period still remains a mystery to astrophysicists.
Together with V. A. Kotov, he performed a new analysis of the nucleus of the Seyfert galaxy NGC4151, which was studied in 1968-1986 using the U filter.
In 1971, at the suggestion of the director of the P. K. Sternberg State Astronomical Institute, Professor D. Ya. Martynov, he began observing the X-ray source Cyg X-1, then just identified with the star. Subsequent observations of VM February X-ray sources (CygX-1, NegX-1, Cyg X-2, ScoX-1) greatly contributed to the establishment of their nature. He was the first in 1972 to establish the photometric periodic variability of CygX-1 and together with R. A. Sunyaev and A. M. Cherepashchuk explained this variability by the effect of ellipsoidal optical star due to the tidal action of a compact object - a black hole.
In 2001, V. M. Ljutiy produced a spectrophotometer for photometry of images with an adjustable acousto-filter.
Since 2004 he has been a professor at M. V. Lomonosov Moscow State University.
In 1999 he was awarded the title of Honored Researcher of M. V. Lomonosov Moscow State University. He was awarded the bronze medal of the Exhibition of Economic Achievements for his achievements in the study of the active nuclei of galaxies.
V.M. Ljutiy was a member of the editorial board of the magazine "Letters to the Astronomical Journal".
He died in 2010, according to other sources, on April 14, 2009 in the Naukoviy village of Crimea.
Main scientific interests and discoveries of V. M. Ljutiy, they are in the field of studying the active nuclei of galaxies and X-ray sources in binary stars. He is a author and co-author of over 250 scientific papers.

For as long as humanity has gazed upward, the night sky has been a source of fascination, wonder, and endless curiosity. The stars that light up the dark canvas of the night, the planets that dance across the sky, and the boundless mysteries of the universe invite us to question, explore, and dream. This guide serves as a compass to understand the vast realm of astronomy, lead you through the cosmos, enhance your understanding of the world, and inspire you to discover your place within this universe....
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.This article will examine how important data science is in space technology and how it's changing our journey into space. We'll cover how data science is making our space missions smarter and helping us solve the mysteries of space...
