Explanation:
Comet Hale-Bopp became much brighter than any surrounding stars. It was seen
even over bright city lights. Out away from city lights, however, it put on quite
a spectacular show.
Here Comet
Hale-Bopp was photographed
above Val Parola Pass in the Dolomite mountains surrounding Cortina d'Ampezzo, Italy.
Comet Hale-Bopp's
blue ion tail
was created when fast moving particles from the
solar wind struck expelled ions from the comet's nucleus.
The white dust tail is composed of larger particles of
dust and ice
expelled by the nucleus that orbit behind the comet.
Observations showed that Comet Hale-Bopp's nucleus spins
about once every 12 hours.
