Astronomy is an observational school with a focus on observational data and some theoretical tools. Astronomy is the study of our universe and the oldest science in the universe and it is different from almost all. Astronomers can only see what people see in space. Hence astronomy has always been an observational science. But whereas science was built on observation. It was quite clear through observation that the Earth was flat too early for humans. Astronomers can only see what people see in space. Astronomy is made up of two words, Astro and nomy. Astro means stars and nomy mean a specified area of knowledge. Astronomy is a branch of science studying space and celestial points and bodies.
We study or do research on things outside the Earth like Sun, Moon, Stars, and other's planets, it is called Astronomy. Cosmology is a branch of astronomy. Cosmology is made by two words, cosm, and ology. cosm means cosmos. In cosmology, it is told about the origin of the universe. It covers big topics such as the Big Bang and the future of the universe. Cosmonauts and Astronauts are the same. Cosmonaut does not relate to the cosmos. in Russia, Train spacecraft are called cosmonauts. Similarly, in America and other countries, training spacecraft is called astronomy. Astrology is not a science and historically has nothing to do with astronomy. astrophysics is the study of physics of Astronomy and focuses on the behavioral properties and motion of objects in the universe. Astronomers are those scientists who are in the field of astronomy. According to modern times, astronomy is in two major categories, first is observational Astronomy. Observations are made with the help of telescopes in observational astronomy, but nowadays it is the time of computers, so computational telescopes have come into existence. Due to this computers collect a lot of data and it is used to compile it. Second is the Theoretical Astronomy. In theoretical astronomy, by analyzing the old data and the present data, they generate information about exoplanets, other galaxies, other stars, and solar systems and create unique models. In this way, it is read in a theoretical way, and it is used in theoretical astronomy. Both observational astronomy and theoretical astronomy have been running parallel. It is also very important for each other. Galactic astronomers study our Milky Way galaxy, while extra-galactic astronomers peer outside our galaxy to determine how collections of stars change and die. Optical astronomy uses light that the human eye can see, and thus analyzes the chemical composition of stars and galaxies.
Do you know about Knowledge of astronomy?
Astronomy
observes and studies outside the Earth like Sun, Moon, Stars, galaxies,
and other's planets. A
few studies of astronomy started from the time people were born. People used to
wonder how this star’s moon and sun work.
Early astronomers noticed sky patterns and attempted to organize them to track and predict their motion. Galileo Galilei was an Italian astronomer, engineer, and physicist. He made major improvements in telescopes, and it became easier to see the planets. he made many discoveries including four major satellites of Jupiter known as the Galilean moons and later discovered the spot on the Sun are called sunspots. Johannes Kepler was a famous astronomer, astrologer, natural philosopher, and mathematician. And he came up with the planetary laws of motion that describe how the planets orbit the Sun. Then Isaac Newton came along with the explained the physics behind the solar system. Isaac Newton was the greatest astronomer, mathematician, and physicist among the most influential scientists. he has used the laws of celestial gravitation and dynamics.
Celestial bodies are the objects that exist in the
universe such as the Sun, Moon, Earth, Saturn, Neptune, Venus, Mars, Uranus,
and Mercury. the celestial body is two types of stars and planets. objects that
have their own light. Such celestial bodies are called stars. Sun is also a
type of star. Those who receive light from others are called planets such as
Venus Mars Mercury Earth Jupiter Chiron Neptune Saturn Uranus. the moon
revolves around the Earth. Sun, Moon, and earth round around each other. That's
why the moon is setelight. The Earth is around the Sun, that's why the Moon is
not a planet.
The energy produced when fusion reactions convert hydrogen into helium and other heavier elements. light dots are visible because of the great distances. Sun and the stars are balls of hot glowing gas. stars move really very large in size because of the vast distances of the stars. Apart from the Sun and the Moon, there are some other planets also that round around the stars.
