Cool Science Facts: Metal in Space

Is this true? Because I was one of those kids who always wanted to be an astronaut until I got glasses in like the 5th grade and all such dreams slid away. I went to Space Camp and did my 6th grade research project on rocketry and never heard about this. Not to mention all the science fiction I read. These are all top research activities, so I am dubious.

If it’s true, it’s the coolest thing ever. Which means it’s probably crap, but I’m leaving it here until I can find some evidence one way or the other. Alas, it was a neat image.

Update - Looks like it’s theoretically possible, but that the surfaces would have to be super clean and smooth. There are some details on Wikipedia.
