I am very interested in this astronomical phenomenon.

The relationship between astronomy and physics and geography is not subordinate. Astronomy is an independent science with a long history, and it may be one of the oldest disciplines in the world.

Astronomy studies all kinds of celestial bodies. The earth is also a celestial body, so the whole earth is also one of the research objects of astronomy, but the specific stratigraphic structure belongs to the category of geography.

Astronomy intersects with physics, geography, biology, meteorology and many other disciplines, and is widely used in many fields of human life.

At first, the ancients determined the time, direction and calendar by observing the sun, moon and stars in the sky, and recorded the astronomical phenomena. This was the beginning of astrometry, a branch of astronomy. Geocentrism appeared in the 2nd century, and Heliocentrism appeared in16th century, which overthrew the dominant position of geocentric theory and made astrometry reach its first peak.

/kloc-Galileo invented the astronomical telescope in the 0/7th century, and celestial observation entered a new era.

Newton, another contemporary giant, founded Newtonian mechanics, which prompted another branch of astronomy-celestial mechanics to appear formally. It makes astronomy enter a new stage from simply describing the geometric relationship and motion of celestial bodies to studying the interaction between celestial bodies and the causes of their motion, which is a great leap in the history of astronomy.

/kloc-The invention of astrophotography and spectroscopy technology in the middle of the 0/9th century enabled astronomers to further study the physical properties, chemical composition, motion state and evolution law of celestial bodies, thus deepening the essence of the problem, thus creating a new branch of astrophysics, which is another major leap in astronomy.

In the 20th century, radio astronomy appeared, and achieved what is called "the four major discoveries of astronomy": microwave background radiation, pulsars, quasars and interstellar organic molecules.

At the same time, human beings have broken through the shackles of the earth and can observe celestial bodies in the sky. Besides visible light, ultraviolet rays, infrared rays, radio waves, X rays and gamma rays of celestial bodies can also be observed. These have made great progress in space astronomy and greatly influenced the achievements of modern astronomy.

At the same time, the prediction and calculation of astronomical phenomena can also help human beings to predict disasters (meteor shower damages satellites, solar magnetic storm interference, astronomical tides and so on). ), you can also carry out biological research (when the sun and the moon run, organisms will have various periodic physiological activities and reactions. ), and there are many many aspects. If you are interested, you can look for it yourself.
