BBC News is reporting that a big ol' rock has been discovered in space that, at least for the time being, is on a collision course with the Earth, and if it holds to it's currently known course will impact on or around February 1, 2019.  Now it's a bit early to stand on a street corner screaming the end is near, there's still a lot of observation to be done to determine it's orbit and if it really is going to hit us.

I like the picture they've got on the article.
