In the search for Earth-like planets a group of astronomers close to our solar system several new bodies. Nearest is 39 light-years away and orbiting together with three possible candidates around dwarf star called Trappist-1. Whether there is life, we will find out “in our generation”.
Are we alone in the universe? The question is asked by mankind long in entertainment industry as well as astronomers. First prerequisite: where is nearest habitable world? And for some must come together: the temperatures must be moderate, there is liquid water, and the size should be comparable to that of the Earth to keep evolution on the similar path.
The discovery of one or the other existed in recent years, as the two planets Kepler-438 b and Kepler-442 b and the extra-solar planet GJ 1132 b, but the search is still after the famous needle in a haystack.
Small cool star with three planets more likely have atmosphere.
Now an international team of astronomers has found three of these needles: straight once 39 light years away there is a small cool star with a mass of approximately 8% and a luminosity of about 0.05% of the Sun revolve around the three celestial bodies. At a distance, measured the radiation of the star, offers the conditions for life.
The results of their research have published scientists under direction of Michaël Gillon of the Institut d’Astrophysique et geophysics at the University of Liège in Belgium early may in the journal “Nature”. The planet Trappist has even its own website where you can get an impression from the planet and State-of-the-art.
