Asteroid Collision with Mars

Newspaper current event by VnutZ on 21 December 2007, tagged as astronomy, space, asteroid, and mars

Astronomers recently upped the odds of asteroid 2007 WD5's impact with Mars as 1 in 75. The asteroid is calculated to be equivalent in size and destructiveness to the object that impacted Siberia in 1908, known as the Tunguska event. It has been years since astronomers were able to witness such a cosmic collision, the last being the extraordinary impact of the Shoemaker Levy 9 comet on Jupiter. 2007 WD5's collision is anticipated for January.
