Life is speculative, but it's worth considering, says Duncan Forgan, an astrobiologist at the University of St. Andrews in the United Kingdom, who did not participate in the study, but says he is close to the team. "It really opens up the field in terms of the amount of objects that we could then think, well, these are habitable regions," he says.

The planets, like Earth and the living beings that inhabit it can be a infrequency. In the Milky Way, our galaxy, three out of four stars are red dwarfs like Trappist-1. So far, three solar systems with seven planets and a total of 10 habitable worlds have been discovered. The new finds breaks all records as it houses the largest number of terrestrial worlds and also contains three habitable, explains Ribas.
After the discovery of the new solar system around the star Trappist-1 you have to answer several questions to confirm if they harbor life and to know if someday humans will be able to analyze it. While some of these unknowns could be solved in a few years, others require technologies that may not be available for centuries.

The panorama can not be more optimistic for Trappist-1 (it is always better that name than its official name of 2MASS J23062928-0502285) can shelter the first sign of life outside our planet.

A team of astronomers has revealed the first system known to harbor seven Earth-sized planets around an individual star (called TRAPPIST-1b, c, d, e, f, g and h). Three of these planets lies within the habitable zone, the area around the star where a rocky planet could hold liquid water on its surface, a key to life as we know it.
