Supernovas in the Lab

Not literally, of course, but it's fairly close.  It's also pretty cool.  By firing a laser 60,000 billion times more powerful than your standard laser pointer at a thin carbon rod, scientists are able to approximate a supernova explosion.  This is very cool, of course, but they are doing this for a good reason.  Scientists expect supernovas to expand in all direction uniformly, but this is not always the case.  Sometimes they have twists and knots, and we're not entirely sure why that happens.  It was suspected that it was caused by patches of dust that interrupt the explosion, which in turn created magnetic fields that distort the star remains into unusual shapes, but we were never sure.  By placing objects in with the carbon rod, we were able to simulate stellar clouds of gas and dust, and the smaller experimental version of supernova behaved in the same way as regular supernova.  This is interesting news, but you know what?  I want to make a supernova with big giant lasers, that is something that I want to do.
