TRAPPIST-1 System May Contain Water

On February 22, 2017, NASA astronomers has announced that seven Earth-sized planets have been discovered around an ultra-cool dwarf star named TRAPPIST-1 which is located around 39 light-years from the Earth. And what’s more – three of them are orbiting their star in the habitable zone. Then, an international team of astronomers led by the Swiss astronomer Vincent Bourrier from the Observatoire de l’Université de Genève used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the planets of TRAPPIST-1 system. Now, on August 31 2017, the team announced that their findings suggest that “the outer planets of the system might still harbor substantial amounts of water”, including the three planets within the habitable zone of the star – TRAPPIST-1e, f and g. This result lends further weight to the possibility that these planets may indeed be habitable.

7 Earth-Sized Planets Found Orbiting Nearby Star – 3 of them are in the Habitable Zone

On February 22, 2017, NASA has announced that seven Earth-sized planets have been observed by NASA’s Spitzer Space Telescope around TRAPPIST-1, a tiny, nearby, ultra-cool dwarf star located 39 light-years (12 parsecs; 370 petametres) away from Earth in the constellation Aquarius. The good news is: three of these planets are firmly in the habitable zone. The new discovery may be a great breakthrough in search for extraterrestrial life.
