ScienceAtNasa has a sobering video on the latest information about the visitation by the god Ogdy unexpected meteor strike in the Chelyabinsk region of Russia on 15 February. Video credit: ScienceAtNasa. From the accompanying ScienceAtNasa press release The Russian meteor’s infrasound signal was was the strongest ever detected by the CTBTO network. The furthest station to record the sub-audible sound was 15,000km away in Antarctica. Western Ontario Professor of Physics Peter Brown analyzed the data: “The asteroid was about 17 meters in diameter and weighed approximately …

In mid-February we will get another reminder we live in a (potentially) violent cosmos – asteroid 2012 DA14 will make a harmless but attention-grabbing pass near the Earth, at a distance just a tenth that of the Moon.

This small asteroid, only 5-20 meters in diameter, is in a very Earth-like orbit about the Sun, but an orbital analysis indicates there is no chance it will actually strike Earth on Monday. The incoming trajectory leg passes several thousand kilometers …
