Comet Hale-Bopp Signed
This is the most beautiful shot of 1995's Comet Hale-Bopp, a huge naked-eye comet that displayed a "bifurcal" tail. The blue tail was the ion tail, glowing gases which always pointed away from the sun, as it was produced by the solar wind, and the pinkish dust tail, from solid particles stripped off the nucleus, which always points into the orbital track of the comet. Signed in silver by Tom Bopp,the co-discoverer of the comet. (see a DETAIL) NOT AVAILABLE OUTSIDE USA
