In late September 2003, astrobiologist Maggie Turnbull from the University of Arizona in Tucson identified 37 Geminorum as one of the best candidates for hosting Earth - type life from a shortlist of 30 stars (screened from the 5,000 or so stars that are estimated to be located within 100 ly of Earth) that were presented to a group of scientists from NASA's space - telescope project, the Terrestrial Planet Finder (TPF), which will search for habitable planets by using visible light with the «signature» of water and / or oxygen from an Earth - type planet after its scheduled launch around 2013, and the ESA's Darwin project involving six space telescopes (Astrobiology Magazine

host stars.
Thus far, Kepler has found 48 planetary candidates
in their
host star's habitable zone (of which 10 are near Earth - size), but this number is a decrease from the 54 reported
in February 2011 only because the Kepler team is now applying a stricter definition of what constitutes a habitable zone
around stars to account for the warming effect of planetary atmospheres, which would move such a zone away from the
star, outwards
in orbital distance resulting
in longer orbital periods (NASA news release; and Kepler Press Conference slides —
in pdf).

Whilst all the exoplanets discovered
around the red dwarf, known as TRAPPIST - 1, are capable of

On July 21, 2003, some astronomers provided evidence from recent discoveries of giant extrasolar planets
