Hubble Space Telescope, the world s first space telescope Hubble Telescope

Edwin Hubble (also known as the father of galactic astronomy) One of the famous figures of modern cosmology and the founder of extragalactic astronomy, he established Hubble's law.

If you don't recognize him, you may think that he is a relatively advanced, powerful astronomical telescope, but he is in outer space.

Friends who like astronomy know that if you make astronomical observations in the city, the observation effect will definitely not be good, because it will be affected by environmental pollution, the earth's atmosphere and other factors.

The Hubble telescope has an absolute advantage in the observation distance and visible range in space, without factors such as the earth's environmental pollution.

When Hubble was taking the first shot, scientists found that there was something wrong with the galaxy from Hubble's telescope**, so they conducted further examination, only to find out that there was a problem with the lens of Hubble, even though the lens was the best in the world at the time.

Three years later, the astronauts replaced the Hubble telescope with new lenses and modified them to allow the Hubble telescope to be photographed from the ground up.

The Hubble telescope has been working for more than 30 years, photographing a large number of galaxies** and making a huge contribution to scientists' astronomical research, but Hubble has not been able to observe more distant galaxies due to physical factors.

Astronomers generally choose to observe the stars on a clear night because it is easier to see the stars without clouds and fog, but even then, atmospheric turbulence and scattering in the atmosphere and the ozone layer, which absorbs ultraviolet rays, limit the ability of telescopes on the ground to make further observations. As a result, astronomers began to develop space telescopes.

The Hubble Space Telescope is designed to free itself from the limitations of the atmosphere on ground observations, and astronomers have been developing telescopes that can obtain clearer observation images. The space telescope was developed in response to such a need. In fact, back in the 40s of the 20th century, the concept of space telescopes appeared.

After about 50 years of development, the first space telescope was finally successfully developed and launched.

This space telescope, named after the famous American astronomer Edwin Hubble, is the world's first telescope to float out of the ground and in space. The Hubble Space Telescope is expensive, and because it is located above the Earth's atmosphere, it is not disturbed by atmospheric turbulence, and the images and spectra it obtains are extremely stable and repeatable, and its capabilities far exceed those of astronomical telescopes on the ground.

Since its launch in 1990, the Hubble Telescope has been in orbit for more than 30 years, and this lone observer in orbit has made great contributions to mankind's observation and understanding of the universe. 365 days a day, 24 hours a day, every minute and every second records information from distant parts of the universe. With its help, mankind learned about the evolution of galaxies in the universe, the formation of black holes, and the first discovery of dark energy.

In the 30 years of the sea of stars, the Hubble telescope has shown us the gorgeous and colorful world of the universe, the pure beauty and striking novelty of the universe, which has had an extraordinary impact on mankind. As the longest-running in-orbit observer, the Hubble Telescope has been working beyond its age limit, from the first 15 years to 20 years, and as its life approaches it will be relieved of its responsibilities and replaced by a new, more powerful space telescope.

The new space telescope will carry two more powerful payloads, the Large Area Telescope (LAT) and the Pulse Monitor (GBM), which has a very wide detection range, from 20 million to more than 300 billion electron volts, which can capture photons in a way that the Hubble telescope can't. It has surpassed Hubble by thousands of times in size and difficulty in observation. New space telescopes have the potential to discover more pulsars that don't recognize radio waves, providing critical information for human exploration.

NASA plans to use the capabilities of the new space telescope to create an "infrared all-day spectrogram" that can observe nearly 102 mid-infrared colors, map billions of galaxies in the universe to prove the original idea, and find as much evidence as possible of what happened in less than a billionth of a second after the universe is large." The new galaxy map will also help scientists find water ice and frozen organic molecules around new stars by combining observations from new space telescopes. Further unravel cosmic anagrams.

Perhaps the new space telescope will soon be launched into space on a Spherex rocket, and as Hubble continues to age and the mission finally ends, the new space telescope will take over its important task and make new contributions to mankind's exploration of the mysteries of the universe.

Of course, the first cosmic image we harvested was brought to us by the Hubble Space Telescope, and so far, the Hubble Space Telescope is 30 years old.

You can take images of the smallest pieces of dark matter, and you can take pictures of the universe.

In the past 30 years, the Hubble telescope has profoundly changed our understanding of the universe and made great contributions to the research fields of galaxy evolution, stellar physics, and exoplanets. A large part of the space we see is photographed by the Hubble telescope, giving us a taste of the magnificence of the space universe.
