More than 30 years ago, a telescope was put into orbit with the goal of understanding its enormity being. This was a great revolution in science, after all, a telescope does not go into orbit every day. Do you know that this telescopecalled Hubble, still in orbit?
The Hubble Space Telescope, launched in 1990, made history by being the first telescope to be launched into space. This was another assignment NASA (United States National Aeronautics and Space Administration)
It belongs to the major space observatories.
It consists of four orbiting observatories. In this way, the universe can be observed in different wavelengths (visible light, gamma rays, x-rays and infrared).
Unraveling the secrets of the universe has always been a big dream. In the past, it was only possible to observe stars with the naked eye. However, that changed more than 410 years ago, when Galileo pointed a telescope at the sky.
After the creation of the telescope in 1610, many advances were made throughout the history of science. After Galileo, Hubble became the second revolution in astronomy.
The project began in 1940, but took a long time to put into practice, and involved a lot of research until it took off on five service missions, between 1990 and 2000.
How it works?
The telescope is 600 km from Earth’s surface and has a mirror about 2.40 meters long. It works like a reflecting telescope, allowing you to take pictures from a wide field of view.
Its resolution is much higher, up to ten times compared to the previous telescope. The longest observation spanned about 13.4 billion light-years from Earth.
It is 13 meters long and orbits the Earth at an altitude of 547 kilometers. Solar panels are used as a power source for the telescope, which weighs 11 tons.
Hubble has the ability to produce clean images and has aided many discoveries, such as the age of the universe, the existence of black holes, new planets, and 3D mapping of dark matter, galaxies, and the emergence of stars.
Moreover, the telescope is making sense of the existence of dark matter and energy. They are responsible for maintaining an unknown dynamic of the expansion of the universe.
