Next year, we will begin making detailed maps of the visible sky, while Vera C. Rubin Observatory in Chile will begin working. What it collects will surpass previous sets and is expected to bring success astrophysics.
The first star map can be traced to the Greek astronomer and mathematician Hipparchus around 129 BC. Although none of his maps are available today, his work points to the beginning of a long and important tradition. In 1989, the European Space Agency launched the High Precision Parallax Collecting Satellite (Hipparcos), naming it. In its three years of operation, it was able to accurately measure the brightness, position, and movement of over 110,000 stars in our Milky Way galaxy. ESA’s next project, Gaia, which was launched 24 years later, has increased that number to 2 billion, but its small size means it can look even now in the universe. Next year, the new observatory, Vera Rubin — another 20th-century astronomer — will be operational, and will have the ability to see far into the distance.
This is because the room will be fitted with a large mirror — 8.4 meters in diameter — that will help us to identify not only the galaxies of our galaxy that are too weak to be seen by Gaia, but also the dim light that comes to us from the galaxies ‘seems as far away as billions of light years. Its large appearance means that it will be able to scan the entire sky above it for a few days, after which it will start again. And it will continue to do so for 10 years, producing a number of maps showing the movement of these galaxies in space and time.
This data will help us to understand more about the dark forces that cause the environment to cultivate on a larger scale. It will also be used to search for blackheads. In the 1970’s, it was Rubin who first presented the clue that there is more to the universe than the brightest things we can see. By photographing the position and movement of stars in the galaxies, they showed that the speed at which they revolved around their galaxies was too high for the invisible objects to provide the gravitational force needed to be stored inside. way. In doing so, he established the existence of a mysterious object called dark matter.
Dark objects make up about 85 percent of the universe — in 2022, the respectable Rubin’s observatory will help us to see how this phenomenon affects the design and evolution of galaxies, as well as the shape of the universe itself.
