Did you know that Siberia was hit by an asteroid in 1908? According to wikipedia, "The energy of the blast was estimated to be between 10 and 20 megatons of TNT - 1,000 times more powerful than the bomb dropped on Hiroshima." [LINK]
60,000,000 trees were wiped out. Sixty Million! And here's the crazy thing: the asteroid didn't even reach the ground. It turned into a giant fireball as it burned its way through the sky. That fireball is what hit Siberia.
We tend to forget that all of that stuff is out there. Asteroids, comets, and so much more. It's all scenery to us. Scenery in the sky. Could you imagine a giant fireball with the 1,000 times power of an atomic bomb erupting above Portland? Or any city? Goodbye city.
100 years later, another asteroid is coming - but this time, to Mars.
From CNN: "A newly discovered hunk of space rock has a 1 in 75 chance of slamming into the red planet on January 30, scientists said Thursday ... The asteroid, known as 2007 WD5, was discovered in late November and is similar in size to an object that hit remote central Siberia in 1908." [LINK]
Could you imagine if we had two months to prepare for a one in 75 chance of an asteroid hitting the Earth in January of 08? Talk about starting the new year off with a bang...
Think about that the next time you look up at the sky. I know I will.
