Fastest star

A team from the National Radio Astronomy Observatory and the Harvard-Smithsonian Centre for Astrophysics in the US has spotted the fastest moving stellar corpse till date ? a dense core of a massive star, dubbed B1508+55. Shami Chattrjee, a member of the team, says that the dead star, now moving at a speed of 1,100 km/sec, will eventually escape the Milky Way entirely.

It’s the first step towards building lungs for transplantation or to repair the damage done by incurable diseases like cancer, says the journal Tissue Engineering.
