Meteorites: More than Planetary Destruction

Meteorites, often associated with planetary destruction, can actually give birth to life. Greg Brenica, a cosmo chemist, reveals that meteorites have played a significant role in shaping human culture. From ancient Egyptians using meteorites as decorative ornaments to the Romans worshiping a meteorite as their primary deity, meteorites have left a profound impact on societies throughout history. In addition to their cultural influence, meteorites bring organic materials from outer space to Earth, which has been essential for the development of life on our planet. These extraterrestrial rocks contain complex organic molecules and pre-solar grains that existed even before our solar system formed. Studying meteorites provides insights into the formation of our solar system and the ingredients that make up life itself.
