    Venus is much like planet Earth its composition, but also very different in other ways -- it's bone-dry with little sign of water, experiences temperatures hot enough to melt lead, is enshrouded in a thick poisonous atmosphere of CO2 and sulfuric acid, and even rotates "backwards." Now we may have an explanation for this weirdness ?- a tremendous head-on collision of two bodies may have formed our planetary neighbor.
