In 1990, NASA launched a telescope into space. Although the telescope was smaller and less powerful than those on the ground, it had the significant advantage of viewing stars and planets from space. The Hubble Telescope has beamed thousands of images to Earth and changed the way we think about the universe. One of the senior scientists from the project joins us to talk about how the telescope revolutionized astronomy.

If you can spend another couple of minutes making a pledge of as little as $5, you’ll feel like a superhero defending democracy for less than the cost of a month of Netflix.
