Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14.

Preliminary estimates show that the meteoroid was 15 meters wide and weighed roughly 8000 tons. The resulting airburst would have the equivalent yield of about a 1/2 megaton explosion.
