Sure, you can try and brave the maddening crowds at the shopping mall on Black Friday, but NASA’s got a better out-of-this-world alternative: exploring black holes.

Using the hashtag #BlackHoleFriday, @NASA tweeted a series images and fun factoids about black holes. Now where else on Earth can you get a free deal like this?
