In the coming years, astronomers will be able to collect enough data on a group of exoplanets and find out if we are alone in the universe. The main question is whether these planets have an atmosphere.
NASA employees using the James Webb Space Telescope began studying the most likely places in the Universe where life could be – this is a group of exoplanets in a star system known like TRAPPIST-1. This is reported by Newsweek.
In the coming years, astronomers are expected to be able to obtain enough data on a group of planets outside our solar system, which may help to determine whether other habitable planets exist.
< p>Recently, NASA staff showed a series of impressive images, including the deepest infrared image of the universe ever taken.
But behind all this, you can not see the huge amount of raw data that the telescope continues to collect.
As soon as it became possible to conduct scientific observations with its help, astronomers began to study the single star TRAPPIST-1, which has a system of planets. This red dwarf, located at a distance of about 39 light-years from the Sun, has attracted astronomers since it was discovered in 2017.
At least seven rocky exoplanets found in the TRAPPIST-1 system, close in size to the earth. Initial research has shown that the temperature of some planets may be cold enough to hypothetically suggest the presence of water.
“There are other planets that are close to terrestrial or temperate climates, but usually they are too far away or around too big stars for us to study,” explained MIT's Julien de Wit.
“So we have the only window through which we might be able to see the atmosphere of other habitable planets like Earth “, – explained de Wit, why these planets are valuable.
“The question we are trying to answer now is whether they have an atmosphere? If so, everything becomes more interesting,” Mikael explained Guyon, exoplanet researcher at the University of Liege, who led the team of astronomers who discovered the TRAPPIST-1 system.
