Comet Hale Bopp Over Val Parola Pass

Comet Hale-Bopp, the Great Comet of 1997, became much brighter than any surrounding stars. It was seen even over bright city lights. 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, consisting of ions from the comet's nucleus, is pushed out by the solar wind. The white dust tail is composed of larger particles of dust from the nucleus driven by the pressure of sunlight, that orbit behind the comet. Comet Hale-Bopp (C/1995 O1) remained visible to the unaided eye for 18 months -- longer than any other comet in recorded history. This year marks the 20th anniversary of Comet Hale-Bopp's last trip to the inner Solar System. The large comet is next expected to return around the year 4385.

What is this satellite image looking at? If you guessed “a large pile of worms” you’d be wrong – but not that wrong. It is unremediated dredge tailings aka mining waste. Dawson City, Yukon, was the capital of the Klondike gold rush in the 1890s. At first the gold rush was individual entrepreneurs with their pans and their small stakes on the river. But by the 1920s, gold mining in the Yukon had become big industry. And big industry comes with big waste.

Now, Dawson City is looking to get some of its unremediated dredge tailings made a UNESCO-designated World Heritage Site. They’re being reasonable though. Dawson City doesn’t want all of the tailings protected, just “a representative sample.”
