Number Confirmed planets outside our solar system – known as exoplanets –increased to 6000NASA said. There is a huge variety in these distant worlds, according to the Space Agency, and discoveries, including Rocky Planets, Lava Worlds and Giants Giants are surrounded by their stars.
There are probably many other discoveries on the way. As a result of further monitoring by the Exoplanet Science Institute NASA (NEXSCI), there are over 8,000 potential planets that have been identified and expect confirmation. With future missions he planned, including Nancy Grace Roman Space Telescope and Observatory of residential worldsThe American Space Agency hopes to discover more planets and world worlds with possible signs of life.
This milestone with 6000 planecies appears 30 years after the discovery of the first exoplanet circulating to a star similar to our sun. “This milestone represents the decades of space exploration powered by NASA-EXSPLORATION space telescopes, which has completely changed the way humanity perceives the night sky,” said Shawn Domagal-Goldman, the duties of the director of the Astrophysics department at the headquarters of NASA, Wa statement. “Step by step, from discovery to characteristics, NASA missions built a basis for answering the fundamental question: Are we alone?”
With the augment in the number of confirmed exoplanets, the scientific community was able to build a picture of the planet’s population in the universe. Scientists estimate that rocky planets seem the most common in the universe. They also discovered the planets of the size of Jupiter, which orbit closer to their star than Mercury makes our sun or planet, which have two stars. Some discovered worlds are covered with lava; Others are surrounded by clouds of precious stones.
“Each of the different types of planets that we discover presents us with information about the conditions in which the planets can form, and ultimately, like common planets, such as Earth and where we should look for them,” said Dawn Gelino, head of the NASA exoplanet exploration program in a statement. “If we want to find out if we are alone in the universe, all this knowledge is necessary.”
Although the number of confirmed exoplanets has reached 6,000, there are only about 100, which scientists were able to observe directly. This is due to the fact that lithe from distant worlds is often so tender that it blends into the lithe emitted by the mother star. Detection methods are therefore indirect; Among the most common is Transit methodWhat consists of detecting the planet by observing IT STAR orbits, which slightly darkens for a low time when the planet passes from it from our perspective.
