Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Demidov Lyceum
The Yaroslavl Demidov State University (Russian: ''Ярославский государственный университет имени П. Г. Демидова'') is an institution of higher education in Yaroslavl, Russia. In 1918, Yaroslavl Demidov State University became a successor university to the Demidov Lyceum, which was founded in 1803. History The Higher School of Sciences Pavel Grigoryevich Demidov established the Demidov Law School by private means in 1803. On June 18, 1803, Alexander the First, signed an Edict to the Senate about opening a higher educational institution in Yaroslavl. At first Demidov has been in contact with the Imperial authorities regarding the foundation of a university in Yaroslavl, even going so far as to promise his own private funding to the new institution; however, when this did not materialise the Imperial government decreed that the school was, upon opening, to have the same status as a university but to carry the title 'higher scho ...

Astronomers From The Russian Empire
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth.

Observational astronomers make direct observations of celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate models of things that cannot be observed. Because it takes millions to billions of years for a system of stars or a galaxy to complete a life cycle, astronomers must observe snapshots of differe ...
