Comet Hale-Bopp. Coloured optical image of comet Hale-Bopp (at lower right) with the galaxy M14 in the background at upper left. Red areas are brightest,going through yellow,green,blue to black (dullest). A comet is a ball of ice and dust that has an eccentric orbit around the Sun. As it approaches the Sun its surface evaporates,releasing a tail of dust and vapour that can be millions of kilometres in length. Comet Hale-Bopp was discovered on 23 June 1995 and is predicted to be brightest in the sky in March 1997. Image taken on 23 October 1996; by this time water vapour has just begun to sublimate off the surface | |
