NAS FACT
NAS' Pleiades supercomputer is named after the open star cluster in the constellation of Taurus. The cluster is also known as M45, the Seven Sisters, and (in Japan) Subaru. The cluster is dominated by hot blue stars which have formed within the last 100 million years. Astronomers estimate that the cluster will survive for about another 250 million years.
