Remarkable!

Think of the odds: this meteorite landed 146 years ago in 1864.

What are the chances that something would be flying around the solar system for nearly 4.5 billion years then hit this wee planet which was Created only 5854 years earlier?

Most amazing indeed.

  And, now imagine the sheer number of stars which have gone supernova and sprayed stuff all over the place which eventually collided with planets and whatever else is out there.
  Most of the elements that make up our bodies had be to created in stars that eventually died. The fact that we are made up of the leftovers from dead stars tells me that this isn't so much blind luck, as statistically inevitable. Stars have been exploding and sending stuff throughout the universe for a hell of a long time.
  Now, finding it and identifying it for what it is seems pretty wild. But, if we're made up of star stuff, the fact that there is more of it isn't really that big of a shock.

  Not if you consider "shrapnel" to mean "fragments that are small but not gaseous". The point here is that a nanoscale grain of chromium54 has been found, which suggests it cooled out of the supernova gas cloud and was driven into the meteroite during a collision, so it is a more-or-less pristine piece of supernova condensate that has not been processed further, the way the iron on Earth has, for example.

Not exactly new by mbone · 2010-09-09 05:49 · Score: 1

Finding Chromium 54 in 100 nanometer diameter nanoparticles is new, and pretty cool (although I would not want to be the one operating the tweezers !), but the basic isotopic evidence for a nearby supernova just before (and possibly causing) the formation of the solar system is decades old.

  It's better than new! It's from the future!Last time I downloaded Chromium in August it was at version 7.0 and not even Google can produce releases at that rate. Chromium 54.0 is scheduled for 2016 I think.

The idea is that the supernova exploded, send out a shell of gas (as supernovas do), and that this shell of gas mixed into the nebula forming the solar system, giving us lots of heavy elements, and highly amplified concentrations (but still trace amounts) of various isotopes coming from the decay of very radioactive isotopes only formed in supernova. Since these particular supernova products decay rapidly, in general galactic matter they would be hard to find, so finding their decay products is a clear sign of proximity to a supernova event.
The particles in question here are 100 nanometers across, and presumably condensed as the supernova shell cooled. Calling them "Shrapnel" is misleading - they would make a virus look huge. I would call them smoke particles, but they are even smaller than that.

Oh, and then later larger bodies like the parent meteorite formed, and included these nanoparticles, probably as dust captured by surfaces.
Which Supernova? by Doc+Ruby · 2010-09-09 06:09 · Score: 2, Interesting

Which supernova did this shrapnel originate in? Is it still around somewhere, 4.5Gy later? Do we know where it was, or even which direction in today's sky it would be if it were still there?

  I'm no expert, but I think the question "which supernova this comes from?" is pointless. 4.5 billion years has passed and the remains of this supernova are probably all around half the galaxy. And they are now in form of other stars or planets, or gas clouds in interstellar space. Chances are, it is already mixed with other matter present and the only intact pieces of it are in the form of such grains.

  I used to know but I forgot. You can forget a lot in 4.5 Gy, see.

Great. Now Pluto ranks below shrapnel.

Talk about finding a needle in a cosmic haystack.
I don't know - most elements heavier than iron (or carbon or something like that) were created in a supernova, since their creation by fusion require energy rather than releasing it. So, in a way, we are all full of "supernova shrapnel".
