Space Shuttle Science Shows How 1908 Tunguska Explosion Was Caused By
A Comet
ScienceDaily (June 25, 2009) — The mysterious 1908 Tunguska explosion
that leveled 830 square miles of Siberian forest was almost certainly
caused by a comet entering the Earth's atmosphere, says new Cornell
University research. The conclusion is supported by an unlikely source:
the exhaust plume from the NASA space shuttle launched a century later.
The research, accepted for publication (June 24, 2009) by the journal
Geophysical Research Letters, published by the American Geophysical
Union, connects the two events by what followed each about a day
later: brilliant, night-visible clouds, or noctilucent clouds, that
are made up of ice particles and only form at very high altitudes and
in extremely cold temperatures.
"It's almost like putting together a 100-year-old murder mystery,"
said Michael Kelley, the James A. Friend Family Distinguished
Professor of Engineering at Cornell who led the research team.
"The evidence is pretty strong that the Earth was hit by a comet
in 1908." Previous speculation had ranged from comets to meteors.
