  • Since the dawn of humankind, humans have scanned the night sky pondering the

  • mysteries of the universe, our place in it, and the nature and existence of the

  • higher force or power that put all of those magical points of light in their place.

  • 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

  • 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.
