How many space telescopes are still in space, what are they called?

Hubble Space Telescope, Spitzer Space Telescope, James Webb Space Telescope, Chandra X-ray Space Telescope.

Hubble, Spitzer, Compton, Chandra, etc.

Although it is said that the space station will be fully completed, it will take until 2022, and now our manned spaceflight has entered a mature stage, so it is very meaningful for our country and even for the world, proving the great progress of mankind in aerospace science and technology.

Our space station ordinary people can only be on the TV on the Internet**, in reality, can we observe the true appearance of the space station on the ground, in fact, this is completely possible, of course, it is only the naked eye ** It is difficult to find, because now the vast majority of people's eyes are more or less in contact with the network, more or less myopia, even if there is no myopia, basically the naked eye can not see the space station.

First of all, the altitude of our space station is more than 300 kilometers high, and our space station circles the earth, which is very fast, only about an hour and a half to complete a flight around the earth, and it is not possible to observe it in every time period, the light is too strong, and it cannot be observed in the shadow of the earth itself on the back side of the earth, so if you want to see the space station, the choice of time should be very particular.

Observing the space station, ordinary telescopes are not good, can not clearly see the space station, and there is also the weather conditions are also very affected, want to observe, you must go to the place with less dust and haze, plus the scarcity of clouds in the sky, to meet the above conditions, the rest is some special equipment, more professional equipment to observe better, such as some ordinary miniature astronomical telescopes for observing celestial bodies.

There is also the choice of time, the space station flight route, this is also very particular, just from the flight route, you can observe, the best observation time is actually in the evening when the sky is just dark, and the early morning sky has just begun to light slightly, in these two stages, the space station just flew over, you have more professional observation equipment, plus a good environment and weather, these together, in order to perfectly observe our space station on the ground.

It should be possible, because now our telescopes are developing very well, and some astronomical telescopes can see things outside the earth.

You can't see it with a telescope when you stand on the ground, because it's built in space, it's very far, so you can't see it at all.

It cannot be seen on Earth with a telescope, not even with an astronomical telescope.

The space telescope is as follows:

1. Hubble. Hubble explored distant galaxies with the Hooke telescope with mirrors with a diameter of meters, pinpointing the seemingly faint nebulae in the Milky Way that were actually located millions of light-years away in other galaxies. His research has helped astronomers understand the vastness of the universe.

2. The Haier Telescope in Baloma Hills, California.

The Haier Telescope, which has a 5-meter-diameter mirror in Baloma Mountain, California, USA, can be used to observe the outer edge of the visible universe. Astronomers have used it to make very close observations of distant galaxies, such as the Andromeda Galaxy, and they have measured the Andromeda Galaxy to be 20 trillion kilometers from Earth, twice the distance previously known.

3. Computer-aided observation.

Today's astronomers use computers at all stages of telescope design, architecture, and operation, leading to a new generation of more efficient telescopes, resulting in many different models for many different tasks.

4. Multiple mirrors form a single image.

With the aid of a computer, many images from the mirror can be combined into a single image. The first multifaceted mirror telescope (MMT) in Mount Hopkins, Arizona, USA, was first operational in 1977. The telescope is a row of 6 mirrors with a diameter of 1 meter, which can concentrate the light equivalent to that of a single mirror with a diameter of 1 meter.

5. The electronic coupling device further assists in observation.

The advent of electronic instruments and computers had a profound impact on astronomy, and enhanced images led to the creation of many new insights into astronomy. Electronic sensors with electronic coupling devices (CCDs) can detect the faintest optical signals or detect many different types of radiation. After computer processing, the signals are collated and strengthened, and these signals observed by electronic instruments convey clear information.

Digital processing magnifies even the smallest differences, revealing things that were previously hidden by the Earth's atmosphere and are invisible to the naked eye.

6. Embedded telescope.

Patchwork telescopes have the advantage of being inexpensive and easy to move when repairing. The Keck Telescope in Hawaii, USA, is a 10-meter-diameter telescope made of 36 mirrors. The Keck telescope observes objects that are four times brighter than those seen by the Hale telescope.

7. Hubble Space Telescope.

Excluding visual interference from the Earth's turbid atmosphere, the Hubble Space Telescope is orbiting and observing the Earth at a distance of 600 kilometers from the surface. The Hubble Space Telescope is the most powerful telescope ever built, and it has revolutionized our vision of the universe. In modern times, the computer Internet network is unimpeded, so that the end individual user is not limited by time and space, and can combine the observation telescope of the world (or even in outer space) to carry out remote observations.

It can be immediately combined with advanced computer software for analysis and digital processing.

<> believe that everyone is very curious about astronomical telescopes, can astronomical telescopes really see that far away? Who invented the astronomical telescope? And what are astronomical telescopes used for?

Friends with children at home should be asked by children, is there a jade rabbit on the moon? With the help of astronomical telescopes, we can confidently observe and observe this problem. Through astronomical telescopes, we can observe that the surface of the moon is covered with large and small craters.

If you look at Saturn through an astronomical telescope, you can find the rings around Saturn, you can observe the streaks and great red spots on the surface of Jupiter, and in the depths where the observation environment is better, maybe you can also find those mysterious and beautiful nebulae and galaxies in the universe through the telescope.

The first Italian physicist, astronomer Galileo Galilei, invented the astronomical telescope. He discovered many astronomical phenomena through astronomical telescopes. Telescopes are also expected in space, and space telescopes allow humans to observe the universe more clearly.

This is because ground-based telescopes are affected by the atmosphere when observing space, which can skew the data. Hence moving the telescope into space. You can get more precise astronomical data without the interference of the atmosphere.

The first space telescope took more than 40 years from conception to completion, carrying the hopes of astronomers. In April 1990, the Discovery spacecraft launched the Hubble Space Telescope into low-Earth orbit. Its successful launch gave space the presence of human eyes, and its birth was seen as a milestone in astronomy's march into the space age, as was the Galilean telescope.

It continuously transmits beautiful images of the universe back to Earth, and the Harbour telescope first recorded a huge historical picture of the formation of the universe. It can clearly photograph the various thrilling and magnificent scenes of many stars in the universe after the collision. Let us be fortunate enough to touch the mystery of billions of light-years away and discover the initial state of the formation of the universe.

It is also inferred that the universe was formed between 13 billion and 14 billion years ago.

But we have to say that the Hubble telescope is indeed a little old, and the new generation of the James Webb Space Telescope will inherit its mission in the future, and I believe that the younger generation will complete the mission more excellently and uncover more mysteries of the universe for us.

I know that this kind of telescope can observe the situation in space, and can also see the surface of the planets, and can also see the surface of the moon, and can also see the presence of other stars, which is a very expensive telescope.

As for the space telescope, I know that it is an instrument made by the China National Space Administration to observe stars in space.

I don't know much, I just know that space telescopes can see far away, and they can also see some small things in space, and they can also know more clearly, the cost of making such a thing is very high, and it is also very difficult.

I don't know anything about it, and there is still a certain amount of space telescope, and this kind of telescope is not something that everyone can have the opportunity to see.

Space telescopes, also known as space telescopes, are one of the main observation tools for astronomers, and most optical telescopes used in astronomy are focused by a large curved mirror instead of a lens. Space telescopes ensure that sensitive probes can collect as much light as possible from distant planets, and lenses absorb some of the light as it passes through.

Space telescopes are one of astronomers' main observation tools, ensuring that sensitive detectors can maximize the amount of light emitted from distant planets, while transparent leather mirrors absorb some of the light as it passes through. The Laughing Astronomical Telescope is an important tool for observing celestial bodies, and it is no exaggeration to say that without the birth and development of telescopes, there would be no modern astronomy. With the improvement and enhancement of telescopes in all aspects, astronomy is also experiencing a huge leap forward, rapidly advancing mankind's understanding of the universe.

The largest and most accurate astronomical telescope ever built was the Hubble Telescope, which was also the first space telescope ever built. Named after astronomer Edwin Hubble, the Hubble telescope orbits the Earth. It is equipped with a wide-angle planetary camera, which can take dozens to hundreds of stars, and the clarity is beyond the reach of the ground telescope, and it is more than ten times that of the earth's lead dust telescope, and it can see small insects thousands of kilometers away.

The Hubble Space Telescope is meters long and weighs tons, and its orbit is 600 kilometers above the surface at the outer edge of the Earth's atmosphere, orbiting the Earth for about 100 minutes. The Hubble telescope was launched into orbit in 1990 by NASA and the European Space Agency in cooperation. It is planned that the James Webb Space Telescope will replace it in 2014.

Because the Hubble telescope operates in outer space, the images obtained are not affected by atmospheric disturbances, have excellent phase view, and can also observe infrared spectral images that are absorbed by the ozone layer.

Knowledge development. In 2013, astronomers used the Hubble Space Telescope to discover 5 planets outside our solar system, all of which had signs of water presence in their atmospheres.
