What are the magical secrets of space?

The magical secrets of space include the blue sunset on Mars, the giant reservoirs with 14 trillion oceans of water on the earth, the planets with a temperature of 1, degrees Celsius, more than 4,5 tons of garbage in space, and the total number of stars in the Milky Way galaxy is about 2 billion.

1. The sunset on Mars is blue

For us, we are used to the beautiful orange-red scenery of the sunset, but on the distant Mars, the sunset sky is usually blue. This is because Mars is farther away from the sun, and the atmosphere of Mars is thin, and 96% of the air is carbon dioxide. The atmosphere absorbs the red color spectrum in the sunlight, which makes the color of the sun seen by Mars different from that on the earth. I hope I can know this interesting cold knowledge.

2. Giant reservoirs with 14 trillion oceans

In 211, astronomers discovered huge reservoirs floating in the air, surrounded by water vapor floating around a quasar, but they are not very common in this special place. It is understood that the reservoirs have about 14 trillion oceans of water. Although it is exciting to see, scientists say that quasars in the reservoirs are 12 billion light years away from us.

3. Planets with temperatures up to 1, degrees Celsius

In 217, the hottest planet KELT-9b was discovered. It is a planet in the constellation Cygnus, about 65 light years away from the Earth. So how high is the temperature of this planet? According to research by scientists, the average temperature has reached 4,316 degrees Celsius, and the highest temperature can reach an astonishing 1, degrees Celsius. Mainly because this exoplanet receives more radiation and heat when it orbits the star, it becomes very hot.

4. There are more than 4,5 tons of garbage in space.

Although we often feel helpless about too much garbage on the earth, you may not know that there are also a lot of annoying garbage in distant space. Of course, this is also related to us humans. Satellite debris, paint chips and dust are as big as the whole spacecraft wreckage, which has brought serious impact on the whole outer space environment. According to a related statistic in 212, more than 4,5 tons of space junk remained in orbit.

5. The total number of stars in the Milky Way is about 2 billion

No matter how old we are, each of us may have counted the stars in the night sky and tried to count how many stars there are. It sounds really naive, because it is impossible. According to the research of astronomers, it is inferred that there are only about 6, stars visible to the naked eye, and if the number of stars in the whole galaxy is about 2 billion, as for how many there are in the whole universe, I am afraid no one can make it clear.
