Hubble Space Telescope

From the very beginning of astronomy, from the time of Galileo, astronomers have one common goal: to see more, to see further, to see deeper. And the Hubble Space Telescope, launched in 1990, is a huge step in that direction. The telescope is located in Earth’s orbit above the atmosphere, which could distort and not transmit radiation coming from space objects. Due to its absence, astronomers obtain the highest quality images with Hubble. It is almost impossible to overestimate the role that the telescope played for the development of astronomy – Hubble is one of the most successful and long-term projects of the NASA space agency. He sent hundreds of thousands of images to the Earth, shedding light on many secrets of astronomy. He helped determine the age of the Universe, identify quasars, prove that massive black holes are located in the center of galaxies, and even set up experiments to detect dark matter.

Hubble Hubble’s discoveries have changed the way astronomers look at the universe. The ability to see in great detail helped turn some astronomical hypotheses into facts. Many theories were discarded in order to go in one right direction. Among Hubble’s achievements, one of the main ones is the determination of Continue reading
