People are curious about the vast universe. In the process of human exploration of the universe, black holes, exoplanets, quasars, gravitational waves and so on have been discovered.
The environment on each planet is different. Compared with the earth, the surface environment of most planets is like "purgatory". Every planet in the universe has a different color. There are stars and planets in these planets, among which the colors of stars are red, yellow, white and blue.
The main factor that affects the different colors on the surface of these planets is the temperature on the surface of stars. When their temperature changes, the wavelength of light waves changes, and the change of light wave wavelength will change the reflection color of stars in human eyes.
For planets, colors are also different; For example, Jupiter is gray, Venus is yellow, Uranus is light green and Neptune is light blue.
Saturn not only has a beautiful light ring, but also has more than 60 satellites, six of which are connected with a huge main ring. These satellites have distinctive shapes and colors. For example, Atlas (Titan XV) and Pan (Titan XVIII) look like flying saucers. The colors of these satellites vary greatly, from red to blue.
According to the data collected by the Cassini probe in the United States, scientists found that the appearance of these "orbits around the moon" depends on their relative positions with the halo. The satellite Pan is the closest and reddest to Saturn's rings, while the satellite Epimetheus (Enceladus XI) is the farthest and bluest. The color of Saturn's moons depends on two factors: the red matter pollution in the main ring (probably a mixture of iron and organic compounds) and the ice particles and water vapor brought by the eruption column of Enceladus volcano. In addition, the researchers also found that these satellites may be formed in Saturn's rings, and the particles in the rings accumulate into satellites, and the satellites will continue to accumulate small particles, leading to strange skirt features around the equator of the satellites, which is probably the reason why Pan and Atlas are flying saucers.
This is because the surface composition of these planets is different. Jupiter is a gaseous planet, so its surface is the color of hydrogen and helium. The main component of Venus' surface atmosphere is carbon dioxide. Uranus and Neptune also belong to gas planets, but the surface gas composition is different from Saturn, mainly methane, so the color is different from Saturn.
Planets and stars dot the vast universe, forming a colorful and beautiful landscape. This is a beautiful picture, and we are writing a magnificent chapter belonging to mankind on the blue land.
