Alien Planet GJ667Cc

Newly Discovered Planet is Best Candidate for Alien Life

A potentially habitable alien planet has been found around a nearby star. The planet is located in the habitable zone of its host star, which is a narrow circumstellar region where temperatures are neither too hot nor too cold for liquid water to exist on the planet’s surface. According to Guillem Anglada-Escudé this planet is the new best candidate to support liquid water and, perhaps, life. The researchers estimate that the planet, called GJ 667Cc, is at least 4.5 times as massive as Earth, which makes it a so-called super-Earth. It takes roughly 28 days to make one orbital lap around its parent star, which is located a mere 22 light-years away from Earth, in the constellation Scorpius (the Scorpion). Interestingly enough, the host star, GJ 667C, is a member of a triple-star system.GJ 667C is an M-class dwarf star that is about a third of the mass of the sun, and while it is faint, it can be seen by ground-based telescopes. The discovery of a planet around GJ 667C came as a surprise to the astronomers, because the entire star system has a different chemical makeup than our sun. The system has much lower abundances of heavy elements (elements heavier than hydrogen and helium), such as iron, carbon and silicon. According to researchers the fortuitous discovery could mean that potentially habitable alien worlds could exist in a greater variety of environments than was previously thought possible.
