Gravity Assist: Where are the Goldilocks Stars? With Giada Arney

Without our Sun, there would be no life on Earth. The Sun gives us exactly the amount of heat we need to survive. But our Sun represents only one type of star in the universe. Smaller, fainter stars called K stars are more common in our galaxy and also have planets, but we know far less about them. Giada Arney, astrophysicist at NASA’s Goddard Space Flight Center, is looking at the potential for K stars to host habitable worlds. Learn about how stars affect planetary environments and why complex life on early Earth was impossible.
