※ This video is from <Documentary Prime - Milestone of Scientific Revolution Part 2: Finding the Principles of the Sun and the Solar System> broadcast on August 30, 2011. About 9 billion years after the Big Bang, the debris from a supernova explosion gathered to form the sun and the planets surrounding it. This is how the solar system we live in was born. And the planets continue to revolve around the sun, and the sun emits tremendous light and heat, allowing life on Earth to survive. What laws are at work in these things? Scientists have observed the sky for hundreds of years to solve this mystery. We will go on a journey to find the secrets of the sun and planets that the giants of science have revealed. NASA's Jet Propulsion Laboratory, the center of planetary exploration, is on display at the end of the solar system. Voyager 1 and 2, which were launched 35 years ago, the Galileo spacecraft orbiting Jupiter, and Cassini orbiting Saturn are on display. And their movements are still being tracked today. What did they discover in the solar system? We explore the secret appearance of the planets in the solar system through probes. The human view of the universe changed from geocentrism to heliocentrism Galileo turned his gaze to the sky. Another eye looking at the universe, the telescope, became an important medium that overturned the existing geocentrism that the sun revolves around the earth. The telescope became a tool for establishing today's view of the universe called heliocentrism. Through Galileo's telescope housed in the Florence Museum, we will try to find evidence that the sun is the center of the universe and all planets revolve around the sun. From the revolutionary thinking of Copernicus, who first proposed the heliocentrism, to Galileo's experimental method that proved it, we will go into the scene that changed human view of the universe. The energy of all things, the sun The sun, the source of energy for all living things on Earth. Sunlight and energy fly 150 million km through space and bring life to Earth. What is the principle of solar energy that gives light and heat to the Earth and allows us to live? It is nuclear fusion, where hydrogen turns into helium. The equation that explains this principle is Einstein's E=mc²! Not only solar energy, but also the secrets of the solar system have been revealed over millions of years. Kepler, who discovered the law of planetary orbit. Newton, who explained Kepler's law in terms of gravity. And Einstein, who extended Newton's law of gravity to outer space, we follow the footsteps of the great masters who led the scientific revolution. Another sun rises The National Fusion Research Institute, which is researching a Korean-made artificial sun. They are experimenting to recreate another sun that will generate energy through nuclear fusion reactions and energize the Earth. The principle of nuclear fusion, the source of solar energy discovered by mankind, is expected to play a major role in the creation of new energy. We can guess the future of the sun and the solar system through the scientific steps of the masters who discovered the secrets of the mysterious and enormous energy of the sun and the paths of space probes exploring the solar system. ✔ Program name: Documentary Prime - Milestone of Scientific Revolution Part 2: Finding the Principles of the Sun and Solar System ✔ Broadcast date: 2011.08.30
