Royal Observatory Greenwich Review

Visit Greenwich Observatory outside London. The observatory, built in 1675, is well-known because it is the foundation of modern astronomical navigation surveys: the primary meridian (zero meridian) from here divides the earth into the eastern and Western hemispheres, and the Greenwich Standard Time (WT) is the starting point of different time zones in the world. Its geographic height is at the Earth's average sea level, known as the Earth's level. Greenwich Observatory has made outstanding contributions to mankind for hundreds of years. Now it has retired gloriously as a museum. Its rich collection gives me a wonderful experience for this famous astronomy enthusiast. I did not reluctantly leave until the closure of the Observatory. How wonderful it feels to have both feet on the eastern and western hemispheres at the same time! See Harley's tomb. Halley served as an astronomical observatory here for 22 years until his death. The famous Halley comet was named after him. In addition to his great contribution to science, Halle also contributed to Newton's Principles from its completion to its publication and publication, laying the foundation for modern physics, mechanics, astronomy and philosophy. Instead of gaining any fame and fortune from it, he owed a debt for a long time before paying it off. Fortunately, history has not forgotten him, and he is respected by the world, including me. Looking up at the stars and exploring the universe, the astronomical ancestors, thank you for broadening our horizons for mankind! In the panoramic cinema of the Observatory, I saw astronomical movies, commented funny and humorous, and interacted with the audience from time to time. Laughter bursts were very interesting!
