Simulated 3D Model of IC 443 (IMAGE) Center for Astrophysics | Harvard & Smithsonian Caption 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 blue) have collided with the gas cloud (gray) and are now passing through it. The different colors for the star's remains show the range of velocities for their motion away from the center of the explosion. The model is combined with a visible light image of this field of view from the Focal Pointe Observatory, a private telescope run by amateur astronomer Bob Franke. Credit Simulation: INAF/S.
