This story is a couple of days old, but I neglected to post it earlier. Scientists have discovered some fascinating new details about the Tunguska explosion of 1908:

Their smaller size indicates such collisions are not as improbable as we had believed.”

Because smaller asteroids approach Earth statistically more frequently than larger ones, he says, “We should be making more efforts at detecting the smaller ones than we have till now.”
