    This is very likely to happen, there are a large number of pulsars in the universe, but due to their weak signals, they are easily overwhelmed by artificial electromagnetic interference, and only a small number of them have been observed so far, they are natural data stations that transmit signalsBut the signal is mottled and noisy, and it doesn't help if humans don't receive the instrument very accurately.

    The National Astronomical Observatories of the Chinese Academy of Sciences announced on October 10 that the 500-meter aperture spherical radio telescope (FAST), known as the "eye of China's sky", confirmed the discovery of a number of pulsars, which is the first time that a Chinese astronomical telescope has discovered pulsars. This is a milestone leap in the exploration of the universe of all mankind, after all, in addition to the requirements for instruments, there is also the inability to know the specific parameters of some specific planets, resulting in some cosmic phenomena can not be explained, but now that they can be measured, these problems will be solved.

    Look at pulsars, which are high-speed rotating neutron stars that are produced by stellar evolution and supernova explosions. It is extremely dense, weighing hundreds of millions of tons per cubic centimeter. Pulsars rotate very fast and have precise rotation periods, which is the most accurate clock in the universe, which is why countries around the world are developing high-precision telescopes to find pulsarsBecause he is like a lighthouse in the sea, as long as you see him, you will basically not be far from the shoreIt is unknown whether he will be able to find an extraterrestrial planet suitable for human habitation, but at least he has found a star that can illuminate him.

    Pulsars have important applications in the fields of timing, gravitational wave detection, and general relativity testing, so as long as a pulsar is found,With the continuous development of people's science and technology, the accuracy of the instrument is higher, and it is uncertain to use the pulsar as a transmitter receiving tower.

    I think that although pulsars have great development value, even if it is difficult to tap the value of pulsars in the future, navigation satellites, as an invention of mankind, will not be replaced.

    In the future, pulsars may replace island satellites, but scientists are still studying pulses and have not come to any feasible conclusions.

    There should be this possibility, and the results depend on the future direction of this pulsar and the results of research.

    This is possible, after all, scientists have such a goal in mind, but there may still be some way to success.

    If this is successfully studied, it is still possible, after all, scientists are also aiming for this idea.

    I think it's possible, after all, nothing can be overstated, and with the growth of technology, anything is possible.

    The first to spot pulsars was Bonaire. Pulsars, or rotating neutron stars, get their name from the fact that they constantly emit electromagnetic pulse signals. Pulsars were first discovered in 1967.

    At the time, Bell, who was still a female graduate student, discovered that there was a star in the constellation Fox that emitted a periodic radio wave. After careful analysis, scientists believe that this is an unknown celestial object.

    Because this star constantly emits electromagnetic pulse signals, it is named pulsar. The name of the pulsar is composed of the abbreviation PSR of the pulsar in English and its right ascension and declination coordinates. For example, PSR B1937+21, 1937 means that the pulsar is located at right ascension 19 37, +21 means that it is located at declination +21°, and B means that the declination value of right ascension is the value attributed to the epoch 1950.

    Characteristics of pulsars:

    Pulsars compensate for the energy radiated by consuming their rotation energy, so their rotation slows down gradually. But this slowing down is so slow that the signal period can be more accurate than that of an atomic clock. The age of the pulsar can be inferred from the period, and the shorter the period, the younger the pulsar.

    In addition to high-speed rotation, pulsars also have an extremely strong magnetic field, electrons are emitted from the magnetic poles, and the radiation is very directional. Since the axis of rotation of a pulsar does not coincide with its magnetic axis, the observer receives a pulse during rotation when the radiation is directed towards the observer. By 1999, 1,000 pulsars had been discovered.

    It is a star that evolved after the death of a star, and it is said to be a kind of supernova.

    A pulsar, also known as a wave, is a highly magnetized rotating neutron star that emits a beam of electromagnetic radiation, but this radiation can only be observed when its emitted beam is directed at the Earth, and it can be called a pulsar.

    Pulsars are stars that evolve after the death of stars, pulsars are very dense and rotate fast, sending electromagnetic pulses all the time.

    Supernova, mainly because all aspects of the data of this pulsar are more in line with the conditions and limitations of supernovae, and should belong to supernova.

    Jocelyn Bell Bonaire missed out on the 1974 Nobel Prize in Physics.

    Bonaire was a graduate student of Antony Hewish, and it was she who first discovered pulsars. In 1968, she and Heush published the discovery in the journal Nature. In 1973, they were awarded the Michelson Medal by the Franklin School of Management.

    Unfortunately, in 1974, when the Nobel Prize was first awarded to astronomers, Bonaire's mentor Heush and colleague Martin Ryle were on the list, but she herself was excluded from the Nobel Prize. Many astronomers were outraged, but others argued that Bonaire was merely collecting the data, and that Hewitt's interpretation of the data was the key. Bonaire never argued about her defeat, but the vast majority of reports suggest that she did more than just make early observations.

    The National Astronomical Observatories of the Chinese Academy of Sciences announced on the 10th that scientists have discovered six new pulsars in the Milky Way using the world's largest radio telescope, the 500-meter aperture spherical radio telescope (FAST), which is known as the "eye of China's sky". All six pulsars have passed international certification, and the details of the two pulsars numbered J1859 0131 and J1931 01 were announced at the press conference on the 10th. The former has a rotation period of seconds and is about 10,000 light-years away from the Earth; The latter has a rotation period of seconds and is located about 4,100 light-years from Earth.

    In China, if you want to talk about pulsars, you have to talk about the person behind the "Chinese Sky Eye", Nan Rendong.

    Nan Rendong's name is inseparable from fast. Born in 1945, his life is legendary, after graduating from the Department of Electronic Engineering of Tsinghua University, he worked in a radio factory in Northeast China for ten years. After the reform and opening up, he participated in the Ten Nations Radio Telescope Program.

    This scientist, who galloped in the international astronomical community, was favored by the astronomical circles of the United States and Japan, but in the mid-90s of the 20th century, he resolutely gave up his high salary and returned to China to serve as the deputy director of the Beijing Astronomical Observatory of the Chinese Academy of Sciences. At that time, his salary for a year was only equal to one day's salary abroad.

    Not many people are optimistic about this idea. Can you find the right place? Can the difficulty of construction be overcome?

    These are unknowns, and amid doubts, Nan Rendong took more than 300 satellite remote sensing maps and trekked through the mountains of southwest China. After returning from his visit to the mountains, Nan Rendong had a solid idea in his heart and formally proposed the idea of using karst depressions to build radio telescopes.

    For a few years, Nan Rendong became a "salesman", and he would promote his large telescope project at the conference and foreign countries in China, in order to raise enough funds. "I started to make the whole world sycophants and let the whole world support us. He laughed at himself at one point.

    It was precisely because of Nan Rendong's persistence that China's radio telescope finally landed in Guizhou. On September 25, 2016, the completion of FAST officially entered the trial commissioning stage.

    Bell, who visited China earlier this year and visited FAST, believes that FAST will be able to discover more faint, distant, unique pulsars, and hopes that FAST can spot pulsars orbiting black holes.

    Sure enough, pulsars were discovered.
