New Evidence Suggests 1908 Tunguska Explosion Caused by Meteorite, Not Comet!
The 1908 Tunguska air burst over a forested region of Russia released energy equivalent to up to 5 megatons of TNT, and is one of the largest such events in recorded history. Long attributed to the impact of an exraterrestrial body, the lack of large-scale meteorite material at the Tunguska site has made it difficult […]
Infrasound Waves from Chelyabinsk Meteorite Circled the World – Twice!
A new study in the journal Geophysical Research Letters has shown that infrasound waves generated by the dramatic entrance into Earth's atmosphere by the Chelyabinsk meteorite circled the planet twice, and persisted for almost three days. The study also gives a preliminary estimate of the energy released by the meteorite's desintegration, equivalent to 460 kilotons […]
