Two X-ray space observatories, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and the European Space Agency's XMM-Newton , have teamed up to measure definitively, for the first time, the spin rate of a black hole with a mass 2 million times that of our sun that lies at the dust- and gas-filled heart of a galaxy called NGC 1365 (image above). Measuring the spin of a supermassive black hole is fundamental to understanding its past history and that of its host galaxy. The observations are a powerful test of Einstein's theory of general relativity, which says gravity can bend space-time, the fabric that shapes our universe, and the light that travels through it. The supermassive black hole is spinning almost as fast as Einstein's theory of gravity will allow.

Fascinated by Nasa's latest Mars mission and planning to tune in? Well, good luck understanding the space agency's everyday lingo, which resembles a sort of Martian alphabet soup. In the highly specialized world of spacecraft engineering, there are many moving parts and pieces —
