Approximately 20.5 light years from the <A class="iAs" classname="iAs" href="#" target="_blank" itxtdid="3483915">Earth</A>, Gliese 581 made the headlines in April 2007 when European scientists discovered a <A class="iAs" classname="iAs" href="#" target="_blank" itxtdid="3484049">planet</A>, named Gliese 581c. Dubbed “superEarth,” the planet orbits Gliese 581 and could have water -- and thus able to support life.
