0:00.0 | Hey, Jonathan. Hey, Michelle. Thanks for jumping on this call with me. Hey, |
0:08.9 | don't know how it's going. It's good. It's good. How are you two doing? |
0:12.4 | Doing well. Pretty good. Good. For anyone who's not familiar, Jonathan and Michelle are |
0:20.4 | out of subscures, places, editors. So they look at all of the things that everyone |
0:25.4 | sends in the good, the bad, the weird, I mean, the weird is obviously a given. And they |
0:31.3 | choose what they're going to focus on sort of researching, writing up and getting published. |
0:35.9 | We try and do, you know, as much as we can, but there's a process of selection as part |
0:40.6 | of this. And so that's Jonathan and Michelle. So I'm super excited to ask about what you've |
0:45.5 | been seeing lately, Michelle. Why don't you go? |
0:48.6 | The place that I would like to talk about is Allen Hills in Antarctica, which is a place |
0:54.9 | that like the landscape there sort of lends itself to these like fascinating scientific |
1:01.1 | discoveries, a geologist who spent decades leading a big research project in Antarctica |
1:07.0 | called it a meteorite heaven. There are many that have been found there, but probably |
1:11.6 | the crown jewel of Allen Hills is this small potato shaped rock that was found there |
1:18.2 | in 1984. It's official name is ALH 84001. And it is the oldest Martian meteorite that |
1:29.6 | we know of on Earth. Scientists think that it formed like four billion years ago, maybe |
1:34.8 | in a Martian volcano. And then it made its way to Earth about 13,000 years ago, where |
1:39.6 | it was buried under the Antarctic ice for a long time. And what makes this funny little |
1:45.8 | meteorite so interesting is that it's like sort of the center of a scientific controversy. |
1:51.5 | In 1996, a team of NASA researchers published a paper where they pointed out some of these |
1:57.5 | unusual structures inside the meteorite and have put forth an argument that they are evidence |
2:04.2 | of fossilized microbial life. And you know, it's a really cool idea. But the analysis |
