  • WHEN comet C/1995 Ol (Hale–Bopp) was discovered1, at a distance of seven astronomical units from the Sun, it was more than one hundred times brighter than comet Halley at the same distance. A comet's brightness is derived from the reflection of sunlight from dust grains driven away from the nucleus by the sublimation of volatile ices. Near the Sun, sublimation of water ice (a main constituent of comet nuclei) is the source of cometary activity; but at its current heliocentric distance, Hale… CONTINUE READING
