because Comets reflect light from the sun. This is the same way you see the moon glowing. When a comet's orbit nears the Sun it starts to warm up since they are usually black in colour.
Their bright colors make it look as if they glow in the light.
Neon has a bright, white glow when it has been lit. Plutonium also has a bright glow, due to its reaction with oxygen.
No. Mercury has nothing to do with comets. Comets are objects that orbit the sun independent of the planets.
comets could be very bright

Yes they do. They come in different colours aswell. Mainly Red Green and Yellow.
Neon is a very bright colour!
Yes it will. All you have to do is keep it in the freezer for about an hour, then crack it again and it'll begin to glow. It will not glow as bright as it did the first time though.
That will depend on when you make the trip. There are MANY comets detected each year, although only a few become bright enough to be seen with the naked eye, and very few are bright enough to be seen with the naked eye from bright city lights. We typically detect comets when they are about a year out from the Sun, although a flurry of smaller "Sun-diving" comets were detected only hours before they fell into the Sun in December, 2010.
glow in the dark
Yes but not forever. It will not be as bright or illuminous. The fridge however will slow the dimming down. COOLIES
