A photograph taken by Magellan spacecraft shows a triple crater on the planet Venus. Scientists at NASA's Jet Propulsion Laboratory propose naming the crater field Stein, after American author Gertrude Stein. Other famous women's surnames for the planet's meteorite impact craters include those of playwright Lillian Hellman, anthropologist Margaret Mead, playwright-ambassador Clare Booth Luce and Mary Stuart, Queen of Scots. The craters shown - with widths of 5.6 miles, 6.8 miles and 8.7 miles - were formed when a meteorite broke into three pieces just before impact.
