Comet Hale-Bopp (Credit: A. Dimai and D. Ghirardo) It was also called the Great Comet of 1997 and was a naked eye object for eighteen months. The comet was not only extremely bright, but also had two tails. Mona Evans, "Comets" http://www.bellaonline.com/articles/art33712.asp

Comet ISON. Experienced observers put the comet's magntitude at +5.5 on Nov. 16th. This means it is now fully 10 times brighter than it was only three days ago before the outburst. In this telescopic view the tail is a riotous crowd of gaseous streamers stretching more than 3.5 degrees across the sky.

Three galaxies and a comet, Argentina. (Image Credit & Copyright: Miloslav Druckmuller) You can see part of our own Milky Way with diffuse starlight and dark nebulae. There are also two satellite galaxies of the Milky Way, the Large and Small Magellanic Clouds. Near the horizon is the Great Comet of 2007 Comet McNaught.

Black Eye Galaxy

Why is Comet ISON green? Recent images of Comet ISON along with spectral data. (Credit and copyright: Chris Schur). The comet looks blue-green because some of the elements that surround its nucleus glow that color when heated. Mona Evans, "Comets" http://www.bellaonline.com/articles/art33712.asp
