5/29/2003: Big space rectangle

[Undertoad]

Hat tip to Archer. This Hubble image is really cool-looking of course, but even more interesting because you don't expect to see a rectangle in space. How could it possibly happen?

The full story tells us it's the result of "a very young, fast, bipolar outflow". To me, that sounds like a feature story on youth culture's experimentation with brain chemistry, but it turns out it's all astrophysics.
