Purdue University has unveiled ''Impact: Earth!'' a new website that allows anyone to calculate the potential damage a comet or asteroid would cause if it hit the Earth. The interactive website is scientifically accurate enough to be used by homeland security and NASA, but user-friendly and visual enough for elementary school students, said Jay Melosh, the distinguished professor of earth and atmospheric sciences and physics at Purdue who led the creation of the impact effects calculator. http://www.purdue.edu/newsroom/genera...
