A&A Press Release - Discovery of the Benešov meteorites 20 years after the bolide event

alt

Based on the article “Reanalysis of the Benešov bolide and recovery of polymict breccia meteorites - old mystery solved after 20 years”, by Spurný et al. Published in Astronomy & Astrophysics, 2014, 570, A39

Astronomy & Astrophysics is publishing the spectacular discovery of meteorite fragments 20 years after the corresponding bolide was seen in the skies of the Czech Republic. This discovery was made possible by reanalyzing the trajectory, which moved the impact line by 330 meters. Interestingly, the meteorites found on the ground are of different types, pointing to a parent asteroid of heterogeneous composition. Read more »
