China’s eye of heaven has been upgraded, and the speed of fast sky survey has been increased five times, which is expected to search for possible alien civilizations

Since human beings have the ability to explore the universe, they are full of infinite interest in the universe. At present, the main tool for us to explore the universe is astronomical telescope. The most famous astronomical telescope is the Hubble Space Telescope, from which a lot of human observations of the universe come.

China is a big country in the world, and it is very fast in the development of space engineering. For space exploration, we are not willing to lag behind. The China sky eye radio telescope, which was put into use in 2015, is the largest single aperture and most sensitive radio telescope in the world.

Soon after Tianyan was put into use, it brought us a surprise, especially in the ability of searching pulsars, which is even more powerful. At present, 14 pulsars have been found and confirmed, and dozens are waiting to be verified. Recently, a millisecond pulsar appeared.

China Tianyan has been using ultra wideband single beam receiver before, and its observation capacity is still limited. According to the latest news, China Tianyan 500 meter aperture spherical radio telescope (fast) is installing the world’s first 19 beam L-band receiver, which is expected to be put into use in early June. The most advanced 19 beam feed receiver in the world is jointly developed by Chinese and Australian scientists. With the launch of fast, the speed of sky survey will be increased by 5-6 times, and more scientific observation targets will be expanded.

The world’s first 19 beam L-band receiver is being installed for China Tianyan 500m spherical radio telescope (fast), which is expected to be put into operation in early June. The most advanced 19 beam feed receiver in the world is jointly developed by Chinese and Australian scientists. With the launch of fast, the speed of sky survey will be increased by 5-6 times, and more scientific observation targets will be expanded.

With the application of the 19 beam L-band receiver, “China sky eye” observation will obtain more accurate positioning images of radio sources, discover more pulsars, and observe neutral hydrogen 1.4GHz spectral lines in different distances and directions in the universe, so as to better explore the history of the universe and even search for possible alien civilizations.

Maybe many people don’t understand what a pulsar is. Let’s make a brief explanation. For a pulsar, modern science thinks it is a rotating neutron star. Pulsar is a very special kind of celestial body. We know that in the universe, celestial bodies generally do not emit radio electromagnetic signals. But pulsar is different, it is in constant high-speed rotation, rotation at the same time will send out regular wireless electromagnetic signal.

One way for human beings to find the existence of alien civilization is to receive radio signals from the universe. Therefore, the regular radio signals emitted by pulsars were once excited by scientists, thinking that they had found aliens. When scientists found the source of the signal, they found that it was the pulse. They had to play a joke with us. So far, pulsars, a special celestial body, have been seen by people.

Through continuous search, scientists have found that there are not many pulsars in the universe, and the current understanding of pulsars is that they are rotating neutron stars. However, whether this is true or not still needs to be verified in the future.

After the upgrade of China’s sky eye, more pulsars will be found for research in the future. Maybe the secrets about pulsars will be solved by Chinese scientists in the future. This upgrade of China’s heavenly eye will also be of great help to human beings in their search for alien civilization.

The most interesting thing for human beings to explore the universe is to look for extraterrestrials. The universe is so big that only the earth can have civilization. There may not be a lot of alien civilizations in the universe, and there will be a lot of alien civilizations that are far more powerful than human beings. The reason why we haven’t found aliens is that our space technology strength is limited. With the updating of our detection equipment from generation to generation, with more powerful detection range and ability, some alien creations, such as spaceships and man-made celestial bodies, can be observed in the universe one day.

Will China’s sky eye become the first radio telescope in human history to explore the existence of extraterrestrial civilization? Let’s look forward to this day together.
