Do you know about The Milky Way? đ
In this episode, we'll journey through our home galaxy, the Milky Way, a vast spiral galaxy with over 100 billion stars, including our Sun. Located in the quieter Orion-Cygnus Arm, about 27,000 light-years from the center, our solar system orbits far from the powerful supermassive black hole, Sagittarius A*, which holds the galaxy together. We'll explore the three main types of galaxiesâspiral, elliptical, and irregularâand imagine the technology that might one day let us travel beyond the Milky Way. Finally, we'll consider one of science's biggest mysteries: Are we alone in the galaxy? We'll learn how scientists search for life on planets in the "Goldilocks Zone," keeping us curious about whatâand whoâmight be out there.
Sleep Tight!,
Sheryl & Clark
