The mystery about the Chelyabinsk superbolide continues three years later
Madrid, Spain (SPX) Feb 16, 2016
In 2013 February 15, the approach of asteroid (367943) Duende to our planet was being closely monitored by both the public and the scientific community worldwide when suddenly a superbolide entered the atmosphere above the region of Chelyabinsk in Russia. Three years and hundreds of published scientific studies later, we are still looking for the origin of such unexpected visitor, that caused damage to hundreds of buildings and injuries to nearly 1,500 people. Finding the precise value of its spee ... read more
