Where did our moon come from?
from Short Wave
Earth didn’t always have a moon. In the beginning of the solar system, when the planets were still forming, something happened that would change Earth’s night sky forever: The Moon was created! How did it happen? This episode, co-host Regina G. Barber searches for answers with planetary scientists. With co-host Emily Kwong, they discuss how the moon was likely made, how scientists know and what that might mean for where Earth’s water came from. Check out Regina's reporting on hydrothermal vents. Interested in more planetary science? Email us your question at [email protected].

A previous version of this episode mischaracterized a scientific hypothesis. The episode incorrectly said the idea is that hydrothermal vents may have been the origin of water on Earth. In fact, the hypothesis is that life may have come from hydrothermal vents. NPR Privacy Policy
