    It's the most abundant of rare earth metals, and is low to moderate toxicity.

    So you're saying it's a common rare earth metal? :)

  4. Re:The Problems with Tycho as an Impact Crater by barakn · · Score: 1 · on Hole in Asteroid Belt Reveals Extinction Asteroid

    No experimental explosion at any scale has ever produced anything comparable to the well-defined 1500-kilometer "rays" of Tycho.
    With a plastic tub, a marble, and a dollar's worth of white flour and cocoa powder one can quite easily create a replica of Tycho's rays. Even better examples are the man-made impact craters on the moon at the bottom of this page. One in particular, created by an Apollo 14 rocket stage, shows not only rays but also a central peak.

    I also find this picture of the Sedan nuclear test quite telling. A nuclear explosion releases a large amount of energy in a small area much like an impact. Notice the arching columns of debris, each of which seems to have a unique shape and trajectory. It is quite easy to see how these would form rays as they collapse on the ground, and some seem to come from slightly off-center from the chaotic cloud of the explosion.

    It's frankly staggering how many tests were done. Heaven forbid anyone else would develop nuclear devices and behave anywhere near as recklessly.
