Scientists have discovered a giant version of Earth that could harbor life in a distant galaxy.
The planet, called K2-1
Researchers from the University of Texas and the University of Montreal revealed the surprising findings, which could indicate a perfect habitat for extraterrestrial life. 19659005]
K2-18b even has a neighbor brother planet, the ingeniously named K2-18c, but it is unlikely to harbor life because it is a little closer to its Sun.
Lead author Ryan Cloutier said: " Being able to measure the mass and density of K2-18b was tremendous, but discovering a new exoplanet was fortunate and equally exciting. "
But although the planets may already be full of otherworldly creatures, we probably will never know for sure.  Orbit a red dwarf star 111 light years away – or 625,000,000,000,000,000 miles away – in the constellation Leo.
Boffins were able to obtain the K2-18b measurement using data from the European Southern Observatory assembled with a highly accurate radial velocity Instrument Planet Searcher (Harps).
Harps can help determine the mass and radius of a planet to calculate its density.
They discovered that the planet is mostly rock with a gaseous atmosphere, like earth, but more research is needed needed to be safe.
Mr Cloutier added: "If you can get the mass and the radius, you can measure the apparent density of the planet and that can tell you what the bulk of the planet is made of."
"K2- 18b is now one of the best targets for atmospheric study, it is reaching the top of the list".
The research will be published in the journal Astronomy And Astrophysics.
