Introduction: since the first telescope was born in 1608, the development of science and technology has made it possible for the telescope to see deep space and other things. It has changed from ordinary telescope in hand to space telescope, optical telescope, refraction telescope, infrared and other products with different functions. It can not only be held in hand, but also be large enough to observe the universe
the editor of 330anecdotes network today will introduce two kinds of the largest telescopes in the world, one is optical telescope and the other is radio telescope. China’s observation is further than that of the United States
The largest telescope in the world: the Hubble Space Telescope
The Hubble Space Telescope is a space telescope astronomical instrument launched into the earth’s atmosphere by the United States on April 24, 1990. Its appearance makes up for the disadvantages of earth observation, and allows scientists to discover a lot of knowledge about astronomy room. It is one of the most important instruments in the history of human astronomical observation.
is the largest space telescope in the world
The Hubble telescope, 575 kilometers away from the earth, has opened the door for human beings to recognize the new world. It has observed the faint light emitted by the extraterrestrial system of 13.4 billion light-years In addition, in recent years, it has also discovered objects that can’t be seen by the naked eye, such as the age of the universe, the formation of stars, the death process of stars, black holes, dark matter, water planets, big fat galaxy clusters, butterfly nebulae and so on
The largest radio telescope in the world: China Tianyan;
These are the four unique skills of China Tianyan (Tianyan) summarized by CCTV
On September 25, 2020, a quot; cauldron quot; located in Pingtang County, Qiannan Buyi Autonomous Prefecture, Guizhou Province, was completed and put into use. It is China’s Radio Telescope quot; fast which we call China’s tianyan.
With a diameter of 500 meters, China’s sky eye is the largest single aperture radio telescope in the world, and also the most sensitive.
this project lasted 22 years
According to scientists, the telescope can receive electromagnetic signals 13.7 billion light-years away. CCTV has summed up four unique techniques for it
can receive electromagnetic signals 13.7 billion light-years away
List of brands
the world’s largest single caliber, the most sensitive
3. Millimeter accuracy. After testing for three years, the error of
is no more than 1 mm,
4. Observing dark matter, measuring the mass of black holes, and even searching for possible extraterrestrial civilizations
This also means that the Chinese can use their own telescopes to explore the existence of civilization in the universe and extraterrestrial life
Extended reading: what’s the difference between Hubble hope glasses and China’s fast radio telescope?
They’re actually different telescopes.
The Hubble telescope is an optical space telescope, and it is also equipped with a number of infrared telescopes and cameras.
takes pictures of visible light that we can see with the naked eye
What a radio telescope can see is not visible light with the naked eye, but a telescope that receives and emits weak signals from space.
, the larger the aperture, the smaller, weaker or farther objects can be seen
