The universe is vast, with countless galaxies and stars. No one can say clearly whether there are other extraterrestrial civilizations in the universe, but more people believe that there are extraterrestrial civilizations in the universe. If there are alien civilizations in the universe, how to find them? The best way, of course, is to send a spaceship to explore, so that you can get a close look at some planets that may have extraterrestrial life.
However, this method requires that the spacecraft have the advantage of speed, and the lowest speed also needs to realize the speed of light. However, with the current technology of human beings, it is not known how long it will take to get out of the solar system, let alone realize the speed of light. Spaceships can’t explore the universe on the spot. They can only observe the stars and galaxies in the universe through astronomical telescopes. However, if the distance is too far, we can only see whether there is an alien civilization on the target planet.
In fact, another good way to find alien civilization is to explore and find radio waves in the universe. As long as the technology of alien civilization has developed to a certain extent, it is inevitable to emit radio waves. For example, many human radio waves are emitted into the universe, and the speed of these radio waves can reach the speed of light, and they can also be transmitted very far away. If you are lucky, it is possible It could be received by alien civilizations.
Similarly, the civilization that other alien civilizations in the universe can walk out of the planet must also be inseparable from the communication of radio waves. There may also be many such radio waves in the universe. As long as we can search and receive them, and then research and decode them, we can decipher the contents of the waves, so as to find the possible location of the alien civilization planet and understand a part of their civilization Some information.
The telescope that seeks to receive radio waves in the universe is called radio telescope. At present, the most powerful natural telescope is the Chinese sky eye established in China. With a diameter of 500 meters, it is the largest and most powerful single aperture radio telescope in the world.
There are many radio waves in the universe, most of which are emitted by some stars. In 1992, scientists detected a very bright radio wave without a photo studio through a radio telescope. However, this radio wave has been weakening for the next 23 years. It has been bothering scientists for more than 20 years, and they don’t know what kind of radio wave it is. It’s from cosmic stars Is it from extraterrestrial civilization?
Recently, scientists have been searching for this mysterious radio wave through a large amount of data collected in the past 20 years. By studying the extreme brightness of radio waves and the galaxies that erupted, scientists have finally come to the conclusion that the mysterious radio wave detected by the radio telescope in 1992 came from the supernova explosion produced by a massive star.
The radio waves come from a dwarf galaxy about 284 million light-years away, a super star 40 times the mass of the sun. We know that a massive star will have a supernova explosion at the end of its life, which can emit super strong gamma ray bursts. Supernova explosions are one of the most powerful flashes in the universe. They are like the light in a lighthouse. They emit close gamma rays and propagate directionally hundreds of millions of light-years away.
Scientists believe that the giant star explosion inside the 284 million light dwarf galaxy produced a rapidly rotating and highly magnetized neutron star, also known as magnetostar. With the end of the super stellar explosion, the super radio waves slowly disappear, because magnetostars only occasionally emit rapid radio bursts. It seems that some people’s dream that it is a signal of alien civilization has been dashed.
Supernova explosion is not a rare sight in the universe. The end of the life of any star may be like this, including our sun. The star also has a lifetime. When the hydrogen atoms in the sun are consumed, the life will come to the end. At this time, the sun will expand infinitely to become a red giant. It is most likely that it will explode, release super strong ray explosion, and transmit radiation Hundreds of millions of light-years away.
In fact, the radio wave we detected in 1992 is not the scene at that time, but something that happened very early. It is possible that this super large Hengde explosion occurred 284 million years ago, and it was detected by human beings after a long transmission period of 284 million years. The mystery that has plagued scientists for 25 years has finally been solved, but the journey of human beings to explore radio waves has just begun.
Now that human beings have a powerful Chinese sky eye, they will detect more and more distant radio waves in the deep space of the universe in the future. After screening these radio waves, they will find out some mysterious radio waves for research and decoding. It is believed that if there is an alien civilization in the universe, their radio waves will be detected and decoded by human beings sooner or later. Human beings are not far away from finding an alien civilization It’s far away.
