Astronomers have discovered that three planets are likely to be habitable, and that is because there are signs that they can contain water inside another solar system. The new discovery comes from the Hubble Space Telescope and increases the chances of finding life outside the solar system, On a planet orbiting Trappist-1, 40 light-years away from the sun.
Astronomers said all the orbits around the star were highly significant, as temperatures were light enough to allow for the formation of surface waters, such as lakes and oceans, according to the british Mirror site.
New research suggests that the outer planets in the system still harbor large amounts of water, despite strong radiation from the star, which can lead to massive levels of water loss, said Amore treude, a member of the international team from the University of Birmingham.
Hubble's observations are of great importance as they tell us about the radiation environment of the Trappist-1 planets
especially if they can remain habitable.
Astronomers have monitored the levels of ultraviolet radiation emitted from Terabist-1, which suggests that their internal planets may have lost huge amounts of water in the past eight billion years.
