"The sky is far from us, but our hearts are always filled with sky." We don't want to constantly explore secrets of sky, so there are an infinite number of them. inventions and creations about sky.
In our personal example, from birth to society, we don't have to rely on our eyes all time. In same way, we may need such eyes to understand sky, and this is how Celestial Eye came into being.
When we talk about "Sky Eye", we should think about Sky Eye, built in my country in 2011, which is largest existing radio telescope in world that countries rely on.
From construction to completion of Sky Eye, 260 million yuan was spent in United States. The function of this "eye of sky" is to allow us to better understand universe, explore sky, and at same time receive and decipher signals from universe. The title of "Eye of World" is well-deserved.
But eyes are covered with dust. In recent years, Arecibo has been phased out and even turned into a "pot" for waste."Eye of sky", born in conflict and confrontation
With end of Churchill's Iron Curtain speech, Cold War officially began. During Cold War, United States and Soviet Union competed fiercely with each other. This includes all aspects, including technology and military, and "Heavenly Eye" is a product of this period.
Soviet leader Khrushchev was first to launch a satellite, which was fuse of Sky Eye. The "Eye of Sky" created by United States is designed to contain Soviet Union's satellite strategy and win battle.
An "Eye of Sky" born under such circumstances is undoubtedly a premature baby, an extra one, and it also paves way for dusty "Eye of Sky" behind it.Brightness in "eye of sky"
The Arecibo Telescope, which cost 260 million yuan to build, has a diameter of 305 meters and has long been largest caliber telescope and is known as "eye of world."
To study distant celestial bodies, "eye of sky" is indispensable. The larger aperture of telescope, more sensitive and stronger resolution. The Arecibo telescope had largest aperture at time, so it was also most powerful and sensitive at time.
The contribution of this "eye of world", of course, is great: in 1964, he confirmed time of rotation of Mercury.
He was also first to discover a planet outside solar system, which gave people a deeper understanding of universe and identified many dangerous planets for us.
The Eye of Sky has also sent a series of messages in an attempt to contact alien life. There is a lot of information, including numbers, DNA, human appearance and even information about solar system. We also expect extraterrestrial contact after launch announcement.
But while "Eye of Sky" did not lose sight, no signal from an alien civilization was received."Eye of Heaven" dim and blind
"Dew is easy to dispel, but beauty is fragile." Just when people thought that "Eye of World" would exist forever, fate of "Eye of Heaven" turned here.
When 21st century comes, Soviet Union has long since collapsed, and Cold War, of course, is over. The status of "Eye of Sky", created during Cold War, naturally declined.
The downgrade means that Eye of Sky is not as important and is also underfunded as many companies have dropped support for Eye of Sky, including NASA. . This is last word on blindness of Heavenly Eye.
In 2017, a strong wind blew into eye, that is, Hurricane Maria. As a result of this disaster, eye was damaged, and it was practically unusable.
And often disasters do not happen alone, failures follow one after another. Three years later, a piece of equipment above Eye of Heaven fell off and hit Eye of Heaven, since then Eye of World has been broken and a long crack has formed.About healing of "Eye of Heaven"
America is a capitalist country. What they are after is profit. And "eyes of sky", which are used to detect outer space, will not attract attention of capitalists at all.
Secondly, there are too many funds. At start of construction, US spent $260 million building Sky Eye. It would cost more money if repaired. This is unacceptable to US and is too uneconomical.
There are many alternate eyes in world of Sanlai. This makes them think it doesn't matter if they don't have biggest "eyes in sky". In fact, there are many radio telescopes in USA, but these telescopes are not as sensitive as American "eyes in sky".
These reasons boil down to nothing more than fact that US no longer wants to take on this responsibility, spending huge amounts of money without getting any benefit, and capitalism will not allow such a situation.
Then world went blind.Another pair of eyes of world
In fact, world still has good eyesight. In 2016, Chinese "Heavenly Eye" built by our country gradually entered public eye and became new eyes of world.
My country's heavenly eye is built on a mountain in Guizhou. Due to local terrain, Sky Eye is more stable. After completion of my country's Heavenly Eye, world will have a second pair of eyes and a stronger guarantee.
The "Eye of Sky" of our country has a larger caliber, so it is more sensitive. Moreover, our country "Heavenly Eye" has more functions that can deform and move. In this way, Eye of Heaven can be better protected, and losses caused by natural disasters will not be irreversible.
Although construction time of Sky Eye in my country is short, its efficiency is very high. The discovery of 740 stars was due to my country's Heavenly Eye, which is several times more than number of stars discovered by other equipment.
The eyes of world shone again.Written at end
Mankind's curiosity about sky has not faded since ancient times. How can people not be curious and love such a bright starry sky and a mysterious universe?
Chang'e flying to moon, Kuafu chasing day is a good depiction of this, but in fact Luban also made "wooden magpies" during Warring States period to explore sky; modern times also represent various aircraft, satellites. Exploration of sky and universe has never stopped.
Exploring sky is a dream not only of our people, but of people all over world. As a large country, we must take on more responsibility and contribute to dreams of people around world.
"If a country lives and dies for good of world, don't we avoid it because of misfortune and fortune"Peace is world of people in world. Do what your country can do for world.
The construction of Sky Eye may be detrimental to interests, but it must be built for sake of world, because world cannot be blind. And our country will not allow this to happen, so perhaps in future "eyes of heaven" of our country will be damaged, but we will definitely take responsibility to love and protect eyes of world.
