Intro

How do scientists find out if an asteroid might hit our planet? And what do they do if it’s on a collision course with Earth? We’ll meet a planetary defender - an astronomer who uses radar telescopes to defend our planet from space rocks! Edgard Rivera Valentín grew up in Puerto Rico, next to Arecibo, the world’s most powerful radar telescope. Hear the story of how Edgard became a scientist superhero, and the supervillain asteroids they’re up against. 

A bonus interview episode with Edgard is available to Patreon members who pledge at the $1 level or higher at patreon.com/tumblepodcast.
