Impact event Chicxulub Crater. This crater is centered on the Yucatán Peninsula of Mexico and was discovered by Tony Camargo and Glen Pentfield while working as geophysicists for the Mexican oil company PEMEX. What they reported as a circular feature later turned out to be a crater estimated to be in diameter. This convinced the vast majority of scientists that this extinction resulted from a point event that is most probably an extraterrestrial impact and not from increased volcanism and climate change (which would spread its main effect over a much longer time period). Although there is now general agreement that there
Haughton impact crater at crater sites on a cold, wet Mars. The Mars Institute and the SETI Institute operate the Haughton–Mars Project at this site, designed to test many of the challenges of life and work on Mars. The non-profit Mars Society also operates the Flashline Mars Arctic Research Station (FMARS) at this site and conducts similar research. Haughton impact crater Haughton impact crater is located on Devon Island, Nunavut in far northern Canada. It is about in diameter and formed about 39 million years ago during the late Eocene. The impacting object is estimated to have been approximately in diameter. Devon Island
