From my latest article on The Mac Observer:

If you knew the end of the world was coming, what would you do? Maybe you’d spend a few final romantic minutes with your loved one; perhaps you’d gather with others in your local place of worship. Given TMO’s readership, it’s a fair bet at least some of you would be pounding back pints of beer and stuffing peanuts into your face while those around you covered their heads in paper bags and found a comfortable spot on the floor to lie on.

But what if we were only going to come within 8,000 miles of it being the end of the world? Well, you’d want to download Sky Safari to your iPad or iPhone to track the fifth-closest asteroid flyby of all time, and the first ever to occur in the iOS era.

More info — including instructions on how to track 2011 MD — is in the full article on TMO.
