The mission of TESS once again scored, this telescope has opened a third in their lives exoplanet HD 21749b.
The Kepler telescope already their achievements all monitoring devices eclipsed, but it will not last forever and are gone. But not long music played, and here in the sky had turned bright red a new space star from NASA`s Transiting Exoplanet Survey Satellite, TESS. This satellite is equipped with special equipment that will allow tracking tiny exoplanets flying through the disk of distant stars. The satellite`s been running long enough. To open and show the world three distant exoplanets. So far, the list is small, but this is only because NASA`s Transiting Exoplanet Survey Satellite came into operation only recently. At the latest meeting of the Astronomical society in Seattle, scientists and engineers who work on NASA`s Transit Exoplanet Survey Satellite project, TESS, reported a new discovery, the planet HD 21749b. Planet HD 21749b is 53 light-years away from Earth. You need to look in the direction of the constellation Grid. The planet HD 21749b elongated orbit, though not so prolonged as that of the Earth. Full revolution of the planet around a large star makes in just 36 days. This groundbreaking tool from NASA has previously discovered two exoplanets, but they are a little faster to revolve around their stars, they rotate quickly and do not fall into the field of life of his star. NASA`s Transit Exoplanet Survey Satellite is stable and opens one exoplanet per month on average, which is very good, at least astronomers think. The third planet, HD 21749b there is little likelihood of habitable protein forms, there are terribly hot, the surface temperature reaches 150 degrees with the +symbol. All because the star brightness such as the Sun, and the orbit of the planet HD 21749b is much smaller than that of the Earth.
The planet is much colder than our mercury, but in any case is not suitable for life. This planet astrophysicists exploring space from the Massachusetts Institute of technology, the United States believe that it is not necessary to give up, it is necessary to continue the search further and can be something so there is a suitable.
Planet HD 21749b is just huge, it is three times larger in diameter than our home Earth. It`s super Neptune, super Earth! The mass of the planet HD 21749b in 23 more than the Earth. Scientists can not yet understand exactly whether this world is rocky or gas, but in any case, to consider this world as a planet for the colonization of future generations is not worth it, who wants to live in a frying pan...
