Wow. So it's no surprise that occasionally when some of these celestial bodies came crashing down to earth in the form of meteorites, these cosmic objects would become highly prized artifacts and in some cases used to forge fabled blades known for centuries in legend and verse. In 2016, researchers confirmed that an iron dagger found in King Tut's tomb, more specifically right next to the thigh of his mummy, was actually made of iron from a meteorite. We're talking 3,300 years ago - three millennia and two hundred years before Egypt hit its iron age. That is freaking magical. It's heavy. This has some meat to it. Throughout human history, people of note from czars, to Kings, to Pharaohs have counted blades made of meteorite iron among their most prized possessions. Oh yep. There's iron in there. This magnet sticks to it. I can't get the magnet back off. Okay. And well, I want one too. So my quest is to make one badass sword out of this chunk of iron from the sky. The first step in my journey is to find out exactly what raw material I'm working with. Well known for its social activism, UC Berkeley is one of the top research universities in the world. Further, it is the home of Cosmo Chemist Dr. Christie Jilly-Rehak. Hi, nice to meet you. Nice to meet you. Would you like to see the sample? Yes, I would definitely. All right. Now, in case you're wondering what exactly a cosmochemist researches, just listen to her answer to this. Do you look at something like this and think about its journey? Yeah, absolutely. You just think this was in the center of an asteroid and then he got blasted out by some crazy impact that must have been huge and then it flies through space for millions of years and somehow eventually lands on earth. It's, it's wild. Yep, you guessed it. She's a planetary scientist unlocking the mysteries of our solar system through micro analysis of extraterrestrial samples. And that's what I brought.
