Fun with micrometeorites…

I have to hand it to BBC News, their headline of “Tiny rock excites astrochemists” amused me so much, I just had to take a look at the story.

It concerns a micrometeorite dubbed MM04 — a 150 micron basaltic achondritic micrometeorite to be precise. The tiny grain dates back to the formation of the solar system, and apparently has a chemical composition unlike anything previously seen. Interesting indeed. The news article doesn’t go into details, though apparently the paper’s been published in PNAS. I may have to go looking for that…

EDIT–
I found a picture of if courtesy of Universe Today!

  1. Yep, I know of the Antarctic surveys, I’m just amazed they found something so small. I think I’ll have to try and find the paper too. I wonder if they found it in an ice core sample or similar.

    In Antarctica. There are actually whole Antarctic surveys that go looking for meteorites. It’s one of the best places on Earth to find them.
    Though I agree — it’s pretty damn impressive they found it at all!

  3. How the hell did they find something 150um in size?
