Did You Know?

Students of the Bible know that Noah survived the Great Flood by stowing himself, his family, and two of every kind of creature on his Ark. Noachian is derived from the Hebrew name for Noah. Modern contexts find Noachian used in reference to the Great Flood or, more humorously, to describe torrential rainstorms and flooding reminiscent of the Biblical event. It could be said that usage of Noachian spans even beyond planet Earth. Astronomers studying the surface of the planet Mars use Noachian to refer to the epoch between 4.6 and 3.5 billion years ago when that planet's oldest craters were believed to be formed. This usage is based on Noachis Terra one of the landmasses of Mars. The name, which translates as "Land of Noah," was chosen in the 19th century by Italian astronomer Giovanni Schiaparelli.
