Researchers using the Spitzer and Kepler telescopes of the US Department of the Space and Aviation (NASA) have found that planets in TRAPPIST-1 are formed from rocks.
Astronomers, research, Trappist-1 system that most of the 5 percent of the planet's mass is concluded that this amount of water in and is estimated to be 250 times the size of the oceans in the world, he said.
Trappist-1 is the nearest star to form water vapor atmosphere contains planets, and the stars were recorded on distant planets to frozen water.
Details of the study were published in the journal "Astronomy and Astrophysics".
On the other hand, NASA's Hubble Space scientists using the spectrometer instrument of the telescope, Trappist-1 is thought to be the system of living in favorable areas, d, e, f and g in his review of the planets, at least three of those these exoplanets (d, e, f) Neptune-like hydrogen-weighted found no hot atmospheres.
These three swims in the world, it looks like the planet Venus and Mars-like atmosphere with compact, hence noted that allows the emergence of the diversity of living beings in gas composition. Scientists "g" for the planet stressed that more data is needed.
