While browsing the webb I've been hearing some rumors about a recent discovery about an earth-like exoplanet. When checking wikipedia I found this article (http://en.wikipedia.org/wiki/Gliese_581) that states that "a planet about 1.5x the size of the Earth discovered in 2007. The latter is notable as it is the first exoplanet discovered which lies within the habitable zone of the star."
I thought this would be all over the news by now, but I have found nothing. The wikipedia article seems a bit unreliable too. I have no idea if this is true or just some kind of hoax. Is there someone here who knows whats going on? |
