The plot of data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR (right), amounts to a "smoking gun" of evidence in the mystery of how massive stars explode. The observations indicate that supernovae belonging to a class called Type II or core-collapse blast apart in a lopsided fashion, with the core of the star hurtling in one direction, and the ejected material mostly expanding the other way (see diagram at left).

This plot of data from two space telescopes, NASA's Nuclear Spectroscopic Telescope Array and the European Space Agency's XMM-Newton determines for the first time the shape of ultra-fast winds from supermassive black holes, or quasars.
