Look closely at this object moving through space as you determine its identity.

We can see a bright image of Comet ISON captured as it passes very close to the Sun. The intense heat causes the ice to vaporize rapidly, creating a brilliantly glowing core and a spectacular, long tail for us to observe.
Prompt
Based on its glowing tail, what is this object?
