28 years ago, astronauts on the space shuttle Discovery gently raised the Hubble Space Telescope, or HST, up from the shuttle bay, and released it into space. Geologist and astronaut Kathryn Sullivan commemorated the moment with a short speech, as she floated in the shuttle. It would be a few years (and a repair job) before the truly historic nature of the telescope was revealed, showing us new views of the cosmos, and wonders it wasn’t even designed to study, like exoplanets. But Hubble is getting up there in years, and it’s time for new history to be made. Lots of new telescopes are waiting in the wings: The James Webb Space Telescope, W-FIRST, plus a collection of others vying to be the next big thing in space telescopes. Caterpillars might be the squirming, crawling larval stage of butterflies and moths, but they have defenses, behaviors, and lives of their own. Second grader Nina Del Bosque from Houston, Texas was stung by an asp caterpillar. She wanted to know about other stinging caterpillars in the world and what role they play in the ecosystem—so she sent Science Friday a handwritten letter with her questions. We invited Nina on the show with biologist David Wagner, author of Caterpillars of Eastern North America: A Guide to Identification and Natural History, to talk about the stinging asp caterpillar, the woolly bear, and all things caterpillar. View a few of these unique critters below.
