Fifteen New Planets Hint at 'Traffic Jam' of Moons in Habitable Zone

Volunteers from the Planethunters.org website, part of the Oxford University-led Zooniverse project, have discovered 15 new planet candidates orbiting in the habitable zones of other stars.

Added to the 19 similar planets already discovered in habitable zones, where the temperature is neither too hot nor too cold for liquid water, the new finds suggest that there may be a 'traffic jam' of all kinds of strange worlds in regions that could potentially support life.
