How Earth climate models help picture life on unimaginable worlds

In a generic brick building on the northwestern edge of NASA`s Goddard Space Flight Center campus in Greenbelt, Maryland, thousands of computers packed in racks the size of vending machines hum in a deafening chorus of data crunching. Day and night, they spit out 7 quadrillion calculations per second. These machines collectively are known as NASA`s Discover supercomputer and they are tasked with running sophisticated climate models to predict Earth`s future climate.
