A very special science Friday today!

NASA and JPL are covering the close flyby of a large asteroid today at 14 UTC. That's 2 p.m. EST or 11 a.m. PST. You can view live coverage of the event at http://www.ustream.tv/nasajpl2

Wow, it was a very special Happy Asteroid Day! A double feature!

While everyone was watching the asteroid designated 2012 DA14, another asteroid one third that size entered Earth's atmosphere over Russia, exploded, and created a meteor storm and shockwaves which blew out windows and caused over a thousand minor injuries, mostly from shards of glass from blow out windows.

The JPL link above describes this event as well as 2012 DA14. The two events are completely unrelated. It was just one hell of a coincidence that these two events took place within hours of each other. But image if 2012 DA14 was the one to enter the Earth's atmosphere. At three times the size of the other asteroid, 2012 DA14 would have caused a catastrophic event like the one in Siberia in 1908.

Here's a video of RT New's coverage of the asteroid that exploded over Russia yesterday with some nice video captured from various dash cams (which are very popular in Russia for some reason). Below that is a video on the Tunguska Explosion in Siberia, 1908.

Remember that sound travels much, much slower than light. You see the explosion way before you hear the shockwave.

Here is a good target for the next asteroid:

This wasn't a concern two months ago, when the Mayan calendar was going to kill us all.

I'm not worried, Bruce Willis and Areosmith will save us.

As long as I get Liv Tyler at the end, I'm ok with that.

I wonder how many people watched Deep Impact and Armageddon in the past two days because of the asteroids? I plead guilty to watching Armageddon yesterday, mostly to see Liv Tyler.

Not me, but it did kind of make me want to see "Seeking A Friend For The End Of The World" again.

Night of the Comet (1984), a cult classic starting the gorgeous Catherine Mary Stewart. She has such great hair.

I miss 80's big hair.
