Progress MS-05 and Dragon CRS-10 arrive at the space station

Two cargo vehicles arrived at the international space station almost consecutively. On February 22, the Dragon CRS-10 spacecraft aborted its connection to the complex due to an error in the navigation system that advised to delay the maneuver after reaching a distance of one kilometer.

Life on Jupiter

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.

Are the alliens being the most plentiful?

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. 

Would be the life in newly discovered exoplanets

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.

Discovery of exoplanets: Can there be life in Trappist-1?

Recreation of the new solar system with seven planets like Earth. A NASA telescope Seven terrestrial planets orbiting around a soft and quiet sun, at suitable distances, so that there is liquid water in them. 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 system with seven earths of terrestrial size

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.
