Star struck: asteroids and beetles

Posted: Updated:

Bobby Farlice Rubio of the Fairbanks Museum And Planetarium tells us some cute and scary news in the latest Star Struck.

Dung Beetles use the Milky Way to navigate at night! Scientists from South Africa and Sweden have demonstrated this by experimenting with the beetles both in a Planetarium and out in the field.  This is the same kind of beetle worshipped by the Egyptians as their "Scarabs!"

Also, Bobby talks about the close call with a large asteroid happening on February 15th. Although there is no chance of impact, this asteroid, "2012 DA14," will be coming 13 times closer than the moon, and closer than our geosynchronous satellites, such as the ones that provide TV, Sirius XM, and many weather satellites. But still 22,000 miles distant at its closest pass. Bobby says IF this asteroid did hit (which it won't!), it would yield an explosion the equivalent of a large atomic bomb! 2.5 megatons = roughly 150 Hiroshima bombs!
