If you’re wondering how many extraterrestrials there are in our galaxy, you just have to use a simple equation developed by astronomer Frank Drake in 1961. Just find out how many stars there are, how many support life, how many advanced societies form, and a few other details and we’ll be set.
Ep. 3: Hot Jupiters and Pulsar Planets
You have lived on the Earth all your life, so you’d think you know plenty about planets. As usual though, the Universe is stranger than we assume, and the planets orbiting other stars defy our expectations. Gigantic super-Jupiters whirling around their parent stars every couple of days; fluffy planets with the density of cork; and Earth-sized fragments of exploded stars circling pulsars. Join us as we round up the latest batch of bizarro worlds.
Ep. 2: In Search of Other Worlds
Look down at your feet. There… you’re looking at a planet. Now look into the night sky and you should be able to spot a few more. After that, spotting additional planets becomes really hard, especially when you’re trying to find them orbiting other stars. This week we discuss the techniques astronomers use to locate distant worlds.
