Radiolab http://www.kunc.org en A Beautiful Notion: That Caterpillars Killed Off The Dinosaurs http://www.kunc.org/post/beautiful-notion-caterpillars-killed-dinosaurs For the last hundred years, scientists have been wondering why the dinosaurs disappeared so quickly. Was there one key reason, or several?<p>Volcanologists pointed to volcanoes. Climatologists suggested global warming, or possibly, global cooling. Ocean experts thought the oceans receded. Some biologists blamed egg snatching mammals. Some botanists suggested toxic plants.

They have eight little runways on their bodies for light display. What are they?<p>They're called comb jellies. They're not jellyfish. They don't pulse like jellies. They seem to hang. You can find them bobbing off eastern beaches from Massachusetts to the Carolinas and if you pull them up (you can, they don't sting), they're goopy, gelatinous clumps vaguely shaped like walnuts.<p>But the secret about comb jellies is <em>they aren't bobbing.

All trillions of us on Earth.<p>It's not our first group portrait, but Carolyn Porco, the woman in charge, says it's going to be gasp-worthy. She should know. She helped shoot some of the early ones.<p>What am I talking about?<p>Well, going back a bit, here's the first one, the granddaddy of Earth pictures. It's often called the "Blue Marble" shot, and it was our first look at our whole planet suspended in space, taken in 1972 as the Apollo 17 crew headed toward the moon.
