Silicates being the most abundant minerals that we see on Earth, like quartz is a silicate mineral, for example.

Olivine or peridote, the gemstone peridote is another one.

So these grains predate the origin of the solar system and they provided the nutrients, if you will, for the beginning of the formation of rocky materials and minerals in this solar system because everything got crunched as the gas began to collapse to form the sun and things heated up and then they cooled down and stuff came out.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

But these grains survived that process.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

So they're actually older than our solar system, which is really, really cool.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

And there are people who spend their whole life studying these pre-solar grains, and it's incredible.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Oh, and just one more point about the pre-solar grains is that these, we find them in the meteorites.

StarTalk Radio

That means they survive the geologic processes, such as the water moving through or heat beginning to generate.

StarTalk Radio

And many of them survive to different degrees depending on where we're getting the sample from and what was the original paragraph.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Wow.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Well, you can talk to us about it as you do.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Yeah, that's a great โ€“ I like the way you drew that.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

So from lessons learned from analyzing Bennu, for example, and Rugu, and there's several more papers coming out in the near future from the OSIRIS-REx mission that are going to detail even more interesting results about prebiotic compounds.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

So keep to the literature for that.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Look for that very soon.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

So, yeah.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

So, on that area of Mars, what was it called?

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

I forgot.

StarTalk Radio

Sheena Falls?

StarTalk Radio

Is that what it was?
