Possible Habitable Planet Discovered
Summed up by Rachele Cermak
A planet 120 trillion miles outside our solar system seems to be capable to house life. Planet 581 c's surface temperatures is like Earth's and it may have liquid water since it is orbiting a star known as a "red dwarf" in its habitable zone.
That type of star is larger, gives off less light and is cooler than the Sun but will last longer. Up until this discovery, that type of star was thought to be unable to host life on orbiting planets. About 80 percent of the stars near Earth are red dwarfs.
The planet was discovered by European Southern Observatory's 3.6 meter telescope in La Silla, Chile, while using the HARP instrument. It splits light to find wobbles in different wave lengths. Those wobbles can reveal the existence of other worlds.
It revealed a planet circling the red dwarf star, Gliese 581.
