Dust Older Than The Sun Found In Earth's Atmosphere

Meteorites on the ground or icy comets millions of miles away are usually the only sources of ancient matter from the early days of the solar system.

But in a high-flying experiment, researchers have used a sort of chemical flypaper to scoop up comet dust from Earth's atmosphere?and it appears to be some of the oldest matter in our cosmic neighborhood.

You know, what amazes me most about this experiment isn't the results. I think most of us could have guessed that we would find dust particles in comets that pre-date our solar system. What amazes me most is the creative minds that come up with such unique ways of finding this stuff out.

What also amazes me is that they can use chemical "fingerprints" from the dust to actually determine the gas cloud our solar system originated from. It's like a cosmic Maury Povich Show.
Probably the earliest flyswatters were nothing more than some sort of striking surface attached to the end of a long stick.

LOL!

Yep, it kind of helps put everything in perspective, doesn't it?

Yep.  Sorry to break it to you.  And C3PO?...well, he is Darth's cousin. (twice removed, i think)
