The father of modern astronomy

American astronomer Edwin Hubble (1889 - 1953) was honored by the world as the "father of observing cosmology." Hubble's research plays a very important role in the development of astronomy today.

Edwin Hubble is one of the most famous figures in modern cosmological theory research. He was the man who discovered the existence of galaxies outside the Milky Way and the continuous expansion of the universe. This is also the first evidence for the theory of the Big Bang that describes the process of formation and development of the universe. His great discoveries created a revolution in astronomy and in the scientific thought of mankind. Therefore, people honor him as the foundation for modern astronomy.

Edwin Hubble was born on November 20, 1889 in Marshfield, Missouri, USA. At 21, he graduated from the University of Chicago with a major in mathematics and astronomy. But then he switched to studying Law at Oxford University (England).

However, the passion for astronomy still urges Hubble. He returned to being a graduate student at Yerkes Observatory at the University of Chicago, Winsconsin state. And he successfully defended his doctoral thesis on the subject of 'Researching nebulae based on photographs' at age 28.

The 2.5-meter Hooke telescope

With the 2.5-meter Hooke telescope, Hubble proved 'the scale of the universe' is no longer confined to our Milky Way galaxy, there are countless similar galaxies in the universe. He also introduced a system to classify galaxies based on their shapes such as ellipse galaxies, spiral galaxies and irregular galaxies. His galaxy classification system has so far been used in astronomy.

And in the process of observing, classifying galaxies, Hubble found that galaxies are moving away from each other and that the velocity is proportional to the distance. In 1929, he generalized this into the famous 'Hubble Law' . This law was confirmed as an extremely important achievement in astronomy in the twentieth century, which profoundly changed the view of the human universe, by the time until then, the Astronomers all thought that the universe stood still while Hubble thought that the universe was expanding, parts of the universe were apart. More importantly, he discovered that the expansion velocity of the universe is a constant , which is the Hubble Constant . Even his Hubble Law was regarded as one of the fundamental prerequisites for modern cosmological awareness when considering the Big Bang, the explosion that later formed our universe.

Edwin Hubble died on September 28, 1953 in California. A series of his enlightening works made the world respect him as the "father of observing cosmology" , and he also received many honors and honors. His name is used to refer to many related astronomical terms such as the Hubble Classification Method, Hubble's Law of Optics, Hubble's Constant, Hubble's Law . and especially the telescope. Famous Hubble space.

Studied in the 1970s of the twentieth century, the Hubble glass was launched into space by the US Aerospace Agency in April 1990. Until now, it has been said that it is difficult to find a scientific device that has far more influence than Hubble. It has inspired people's imagination more than any other scientific device and is the source of more than 6,000 research papers. This is also the reason why many people know more about Hubble telescopes than particle accelerators or scanning electron microscopes, although their enlightenment role is similar.

Astronomer Frank Summers of the Space Telescope Science Institute in Baltimore said: 'Hubble has played a huge role in changing the human view of the universe'.

During its past journey, the Hubble telescope (now called Hubble) has made important discoveries in the solar system such as: observing the collision between comets Shomaker - Levy collides with the atmosphere. of Jupiter, stars and interstellar environments (life cycle of dust, gas, stars), supernova explosions (supernova 1987A), black holes, galaxies, expanding universe and explosions Space.

After more than 20 years of operation, so far Hubble Space Telescope still plays an important role in the development of modern astronomy, bringing great achievements and knowledge to the world about the vast universe.
