Space Shuttle Pollution Yields Information

There is new evidence in the debate regarding the 1908 Tunguska event that destroyed 80 million trees in Siberia.

Researchers say that clouds that form at the poles after shuttle launches are due to the turbulent transport of water from shuttle exhaust.

Similar clouds were visible at night long after the Tunguska event.

The Geophysical Research Letters study suggests that an icy comet, rather than a meteor, must have been responsible for the event.
