This NASA collage shows Comet ISON and distant neighbors as see through two Hubble filters. One filter lets in red light, and the other a greenish-yellow color, which is shown as blue here. In general, redder things are older than blue things – this is true both for the crosshair-spiked stars and the smudges of distant galaxies.

8:05 am ET -Comet ISON will fly perilously close to the sun on Thanksgiving Day. If it survives, it will make a gorgeous display in late November and December, coming closest to Earth on December 26.
