A circular rainbow appears like a halo around an exploded star in a new view of the IC 443 nebula from NASA's Wide-field Infrared Survey Explorer, or WISE. When massive stars die, they explode in ...
Scientists constructed a simulated 3D model of IC 443 based on data from telescopes including the Chandra X-ray Observatory. The shock wave (gray) and the remains of the star (red, yellow, green, and ...
In order to understand the origin and acceleration of cosmic ray protons, researchers used data from the Fermi Gamma-ray Space Telescope and targeted W44 and IC 443, two supernova remnants thousands ...
