NASA tells us about its latest and most important discovery


Yesterday NASA announced that today they were going to talk about their latest discovery. Many were the doubts since the United States Space Agency is not very given to this type of announcements if the news is not really important, as well as the fact that a group of its researchers has discovered an unusual system composed of nothing less than seven Earth-like exoplanets.

This new finding has been possible thanks to the possibilities offered by the use of the Splitzer telescope, the Paranal VLT instrument and the TRAPPIST of the La Silla Observatory. As has been commented in an article published by Nature, apparently we are talking about seven planets that orbit the star TRAPPIST-1, located 38 light years from the Sun whose temperature could range between 0 and 100 degrees centigrade.

TRAPPIST-1 could host six potentially habitable exoplanets.

All these planets, it seems, would have a size similar to that of the Earth and, according to the measurements made on their density, it seems that scientists would have come to the conclusion that at least six of the seven planets discovered they would have a rocky composition although, as they themselves announce, they still need to continue investigating for much longer to be able to confirm it with a much greater certainty.

Thanks to this new discovery, new planets capable of harboring some type of life have just been unveiled since we not only have to talk about exoplanets with a rocky structure, but also due to the temperature at which they would even there may be water liquid on its surface, an indispensable condition so far for living organisms to develop.

Based on the statements made by Amaury triaud, co-author of the work:

The energy emission of dwarf stars like TRAPPIST-1 is much weaker than that of our Sun. For there to be water on their surfaces, the planets would have to be in much closer orbits than we can see in the solar system. Fortunately, it seems like this kind of compact setup is what we're seeing around TRASPPIST-1.
