Eye of Deep Space Hubble Telescope
When Galileo Galilei turned his telescope to the sky for the first time in 161, it was difficult for him to recognize Saturn's rings that can be seen in cheap telescopes today. Advances in optics have finally improved scientists' views on planets, stars and distant galaxies. The Hubble telescope, launched in 199, solved the limitations of ordinary telescopes and brought human beings a step closer to understanding the universe.
Hubble telescope has been sending beautiful images of the universe back to the earth continuously. It has made many breakthrough discoveries, which constantly surprises us and makes us lucky to touch the mystery hundreds of millions of light years away. Let's learn the story of Hubble telescope.
Introduction of Hubble Space Telescope
Hubble Space Telescope is the only cosmic optical telescope in the world. In 199, the United States used the space shuttle Discovery to put it into Earth orbit. The telescope is named after the surname of American astronomer Hubble, who proposed the idea of cosmic expansion. It is mainly equipped with wide-angle planetary camera 2(WFPC-2), space telescope imaging spectrograph, near-infrared camera, dark celestial camera and other measuring instruments. Hubble Space Telescope has made great contributions in proving the existence of auroral black holes of Jupiter and Saturn.
Hubble's development history
The design idea of Hubble space telescope originated from the paper put forward by astronomer Lyman Spitzer in 1946. During the Second World War, while developing rocket technology, scientists tried the space telescope project on a small scale, but it didn't succeed. Later, until 1968, NASA finally confirmed the plan to build a reflecting telescope with a diameter of 3 meters in space. After the preparatory work, the telescope project was named Hubble in early 198.
After nearly 1 years of design and manufacture, on April 24th, 199, the Hubble Space Telescope was successfully launched by the space shuttle Discovery at the Kennedy Space Center. Hubble Space Telescope began its mission. Its main tasks are to explore the deep space of the universe, solve the mystery of the origin of the universe and understand the evolution of the solar system, the Milky Way and other galaxies.
naming of Hubble
Hubble telescope is named after American astronomer edwin hubble. Edwin hubble discovered the redshift phenomenon that exists in most galaxies for the first time through observation, and then established the later famous Hubble Law, which is generally regarded as the strongest evidence to prove the expansion of the universe.
At the same time, he was also the founder of galaxy astronomy and the pioneer of observational cosmology, and was later honored as the father of galaxy astronomy. To commemorate his important contribution, NASA named this space telescope Hubble Space Telescope.
Hubble's photo
The Pillar of Creation is one of the most famous photos taken by Hubble. It is made up of 32 photos, showing the evacuation nebula named Eagle Nebula (M16), which is composed of gas and dust. The tallest "column" is four light years long.

The spiral nebula is a planetary nebula in Aquarius, which is one of the closest planetary nebulae to the Earth. Once known as the eye of God, it was also known as the eye of Soren after the movie Lord of the Rings trilogy swept the world in 23.

The Straw Hat Galaxy is located in Virgo, 28 million light years away. There is a super black hole with a mass of 1 billion times that of the sun in the bright area in the middle. The whole galaxy is also named because its structure is flat like a huge straw hat.
