Article Summary
The European Space Agency (ESA) is assessing information about the Chelyabinsk meteor that exploded last week over Russia in the hope of improving the space agency’s asteroid-hunting program. Calculations by Peter Brown at Canada's University of Western Ontario based on the analysis of extremely low-frequency sound waves detected by a global network, was combined with videos, satellite images and eyewitness accounts to allow ESA to construct a more complete and accurate account of the event.
