NuSTAR Puts New Spin On Supermassive Black Holes

by Tammy Plotner February 27, 2013

Checking out the spin rate on a supermassive black hole is a great way for astronomers to test Einstein’s theory under extreme conditions – and take a close look at how intense gravity distorts the fabric of space-time. Now, imagine a monster … one that has a mass of about 2 million times that of […]
