Nearby Exoplanet Is Best Candidate For Supporting Life
by Lisa Winter
Finding new exoplanets is always awesome, but discovering exoplanets within the star’s habitable zone are exponentially more exciting.
A team led by Robert Wittenmyer of the University of New South Wales has announced the discovery of the Super-Earth Gliese 832 c, which could very well turn out to be the best candidate for extraterrestrial life discovered to date. It’s also fairly close, cosmologically speaking, which adds to the intrigue. The team’s paper has been accepted for publication in The Astrophysical Journal, but has been made available online in an open access format on arXiv.org.
Gliese 832 is a red dwarf star that is located 16.1 light-years away in the constellation Grus. Astronomers discovered a Jupiter analog orbiting the star back in 2009, but its orbit takes nine years to complete; far beyond the star’s habitable zone. Gliese 832 c looks much more promising. Though only two planets in the system are known, it appears to be organized quite similarly to our own solar system…
