The number of Confitmed planets outside our solar system – known as exoplanets –Went to 6,000Said NASA. There is a great variety in these distant worlds, says the space agency, with discoveries such as Rocky Planets, Worlds Lava and Gas Giants enveloping their stars.
Plants more discoveries are probably underway. As respect for continuous monitoring by the exoplanet science institute (NEXCI) of NASA, there are more than 8,000 potential planets that have been identified and expect confirmation. With future mission, he planned, including the Nancy Grace Roman Space Telescope and the Observatory of habitable worldsThe American space agency hopes to discover more planets and earth -shaped worlds with possible signs of life.
This important stage of 6,000 plans comes 30 years after the first exoplanet was discovered in orbit to play similar to our sun. “This step represents decades of cosmic exploration motivated by the spatial telescopes of NASA – an expression which has completely changed the way in which humanity vision statement. “Step by step, from discovery to characterization, NASA Missioni has built the basics of the answer in fundamental question: are we halo?”
As the number of Confitmed exoplanets has committed, the scientific community was able to build an image of the population of the planet through the universe. Researchers believe that Sagar rocky planets are the most common in the universe. They also discovered planets of the size of Jupiter this orbit closer to their star that Mercury does not make our sun, or the planets that have two stars. Some discovered worlds are covered in lava; Others are surrounded by clouds of early stones.
“Each of the different types of planets that we discovered gives us information on the conditions under which the planets can form and, last, how common planets like the land could be and where we should look for them,” said Dawn Gelino, head of the Exoplanet Exoplanet Exploration Program. “If we want to know if we are alone in the universe, all this knowledge is essential.”
Although the number of exoplanets confided reached 6,000, there are only 100 that scientists have been able to observe directly. Indeed, the light of the distant worlds is often so weak that it mixes in the light emitted by the parent star. The detection methods are therefore indirect; Among the common mons is the Transit methodWhich implies detecting a planet by observing the star IT orbit, which stops slightly for a brief moment when the planet passes in front of our point of view.
