The 2013 Russian meteor airburst packed the biggest punch from an impact to hit Earth in a century, a roughly 500-kiloton wallop.

A meteor hit Chelyabinsk in Russia in February.
Relatively small (20m), it came undetected. It travelled at 60.000 km/h and exploded when it entered the atmosphere, 23km above the ground. The generated air burst was 20 times more powerull than the bomb of Iroshima; it damaged buildings and injured people tens of miles away.
It tells a lot about kinetic energy, and why scientifics and movie makers are so interested in asteroids. Meteors are also a favorite end-of-world scenario for would be Nostradamuses. Speaking of which, I could not find his predictions for 2014 but an interesting curation by Business Insider.
The smallest exoplanet was also detected this month. With around 1000 alien worlds detected so far, the search for Earth-like, life-capable planets is hotter than ever! More good news from the stars.
