Remember Gliese 581g, the Earth-like planet whose discovery scientists announced two weeks back, saying it could potentially sustain life? Bad news: Not only were the initial reports that "the chances for life on this planet are 100 percent" overblown; now, new data suggests that the planet may not actually exist.
Steven Vogt, the researcher who led the team that announced the Gliese 581g discovery (and the utterer of the now-infamous "chances for life on this planet are 100 percent" line, which he clarified was a statement of personal belief rather than of scientific evidence), based his discovery on a mix of his work at Hawaii's Keck Observatory and previously published data.But the publishers of that old data used by Vogt, who collected it using Chile's High Accuracy Radial Velocity Planet Searcher (HARPS), have come out with new data which lacks evidence for Gliese 581g.
