1050: Lisa Kaltenegger | In Search of Alien Life and Livable Worlds

Are we alone in the universe? Alien Earths author Lisa Kaltenegger joins us to discuss new discoveries in humanity's hunt for extraterrestrial life.

What We Discuss with Lisa Kaltenegger: The universe contains billions of stars and galaxies, with an estimated one out of five stars having a planet that could be similar to Earth in terms of potential habitability. Scientists use various methods to detect exoplanets, including observing changes in starlight and analyzing the light spectrum of planets to detect signs of life-sustaining elements like oxygen and methane. The search for extraterrestrial life involves looking for planets in the "habitable zone" or "Goldilocks zone" around stars, where conditions might allow for liquid water on the surface. The observable universe is limited by the speed of light and the age of the universe (approximately 13.7 billion years), meaning we can only see as far as light has had time to travel since the Big Bang. Anyone can contribute to space exploration and scientific discovery by staying curious, learning about new discoveries, and supporting science education. Even simple actions like looking up at the night sky and wondering about our place in the universe can inspire a lifelong passion for science and exploration. And much more...
