As the world's largest and most sensitive radio telescope, the "Sky Eye" project has come to a successful conclusion, which means that China's major scientific and technological infrastructure has been further improved, and mankind has a deeper perspective in exploring the unknown universe. The success of "Sky Eye" reflects Chinese wisdom, Chinese technology, Chinese power, and also demonstrates China's responsibility.

For the world's scientific and technological community, "Sky Eye" provides the research tools needed to explore the universe. "Major breakthroughs come first with instruments." From the stars in the universe to elementary particles, human scientific discoveries and technological innovations are increasingly inseparable from "high-end" scientific research instruments. The astronomical community generally believes that less than 1% of the universe is luminous matter that humans can see. Scientists often use radio telescopes to improve their ability to observe the universe. In this regard, the sensitivity of "Sky Eye" is more than 2.5 times that of the world's second largest single-aperture radio telescope. Its high sensitivity is likely to help scientists make breakthroughs in cutting-edge fields such as low-frequency gravitational wave detection, the origin of fast radio bursts, and interstellar molecules.

The significance and value of China’s Sky Eye

The significance of “China’s Sky Eye”▼

1. Do not realize economic benefits or search for strange celestial bodies in the short term

1. The main goal of FAST is not to achieve economic benefits in the short term, but to scan the cosmic background microwave radiation and observe and study distant signals and materials in the universe.

For example, gases, microwave lasers and pulsars in the middle of the universe can achieve the most basic understanding of the material composition and evolutionary history of the universe and satisfy human exploration of the unknown universe.

2. FAST will likely search for more exotic celestial bodies, which will be used to observe pulsars (dense remnants of supernova explosions of massive stars) and explore the origin and evolution of the universe, the evolution of galaxies and the Milky Way. etc., you can even search for interstellar communication signals and carry out exploration of extraterrestrial civilizations.

Select millisecond-level pulsars with stable pulse signals from pulsars, which are expected to be used in the field of space vehicle navigation in the future

< p>2. Conducive to data storage and calculation in the field of information science

1. As the "world's first eye" in the field of radio astronomy, FAST's need for data storage and calculation is also "astronomical level" "of.

As one of the first scientific fields to experience an information explosion, astronomy has always been known for its large amount of data and complex data types

2. In the short term, the computing performance requirements of FAST must at least reach More than 200 trillion operations per second, the storage capacity requirement reaches more than 10PB (1PB is equivalent to 1000TB)

As time goes by and scientific tasks deepen, the demand for computing performance and storage capacity will explode. , the amount of data and calculation will be "astonishingly large".

The value of "China Sky Eye" to ordinary people

It can help solve various crises currently faced by mankind

p>

Compared with ordinary people's livelihood projects, various large-scale scientific devices similar to the FAST telescope are too far away from ordinary us.

Many people will not see their current benefits and think that they are "Useless waste, waste of money".

That’s not the case!

▼ "Hertz discovered the working principle of radar when confirming the existence of electromagnetic waves, thus affecting the course of World War II; and the GPS we use now can be traced back to the first artificial satellite launched by the Soviet Union in 1957 . Before Tu Youyou stood on the Nobel podium, we didn’t even know where the research project started more than 40 years ago would lead. However, the discovery of artemisinin saved millions of lives around the world, especially in developing countries.”

FAST research involves many high-tech fields, such as antenna manufacturing, high-precision positioning and measurement, high-quality radio receivers, sensor networks and intelligent information processing, etc. . Therefore, in the long run, FAST is likely to help solve the various crises currently faced by mankind

In 1970, Zambian nun Mary Jucunda gave Dr. Ernst Stuhlinger (NASA (National Aeronautics and Space Administration) Marshall Space The deputy director of science at the Navigation Center wrote a letter asking: How can we be willing to spend billions of dollars on projects as far away as Mars when there are so many children on earth who do not have enough to eat?

Every year, about a thousand new technologies developed from the space program are used in daily life, creating better kitchen appliances and farm equipment, better sewing machines and radios. , better ships and planes, more accurate weather forecasts and storm warnings, better communications facilities, better medical equipment, and even better daily gadgets.

You may ask?

Why design the life-support system for the astronaut lunar module first, instead of building remote physical sign monitoring equipment for heart disease patients first?

The answer is simple: when solving engineering problems, important technological breakthroughs are often not obtained directly step by step, but from the ability to inspire a strong spirit of innovation, ignite imagination and firm action, and the ability to integrate all resources. Challenging goals

Space exploration not only provides humans with a mirror to look at themselves, it can also bring us new technologies, new challenges and enterprising spirit, as well as the ability to persist in the face of severe practical problems. Optimistic and confident attitude.

I believe that what mankind has learned from the universe fully confirms Albert Schweitzer's famous saying: "I look at the future with worry, but still full of good hope"

Significance

For the world’s engineering community, “Eye in the Sky” has enriched the innovative practice of super projects. The reflecting surface is composed of 4450 reflecting units, the feed cabin controlled by 6 steel cables weighs 30 tons, and the measurement angle is accurate to 8 arc seconds on a scale of 500 meters, increasing the satellite data reception capacity by 100 times... "Eye in the Sky" "Extraordinary things are everywhere. There is no such thing as a good thing in the world. A world-famous super project like the "Eye of the Sky" embodies the ingenuity and hard work of the Chinese people. It is the institutional advantage of socialism with Chinese characteristics of "concentrating efforts to accomplish big things" that has enabled the successful implementation of major scientific and technological infrastructure required for high-quality development. It can be said that the success of "Sky Eye" has once again contributed China's development experience to the world.

For the future of the world, the "Eye of the Sky" has become a footnote in building a community with a shared future for mankind. Facing the vast universe, the unknown world and the potential of science and technology, human beings are one community with interests, responsibilities and destiny. "Sky Eye" has shouldered a global mission since its birth. In just 9 years from the start of construction to national acceptance, the "Eye in the Sky" produced more than 300 papers, discovered 146 high-quality pulsar candidates, and played an important role in the international very long baseline interferometry... The great "Eye in the Sky" The project is another precious gift that Chinese civilization has contributed to the world.

“The people are the creators of history, and the people are the real heroes.” Behind the “Eye of the Sky” is the great spirit of creativity, great spirit of struggle, and The great spirit of unity and the spirit of great dreams. It is this kind of national spirit that has created the "Eye of the Sky" and injected strength into the development of China and the progress of human civilization.
