If I'm reading this right, it's the perimeter of 200 miles wide crater of rock moving at 2,125mph. Nothing much is going to stop that, apart from more rock! 174 miles of it. It looks like some of the debris shot out more like a bicycle fork rather than a circle? tbf it's a bit confusing.

Submission + - The world is running out of helium (nbcnews.com)

Submitted by Wildbear
Wildbear writes: Supplies of helium, a nonrenewable element, are becoming increasingly scarce. Superconducting magnets used for MRI machines and other equipment require its extremely cold temperature, which no other element can achieve. Doctors and scientists are wondering how future needs for super-cooling will be met.
"There's only a finite amount of helium in Earth's crust," [Harvard University physicist] Kim said. "Once it evaporates off, it's completely lost into outer space."
