Cosmic Radiation – The Universe’s Invisible Messengers

We dive into the fascinating world of cosmic radiation — invisible yet powerful messengers from the universe. The episode explains how cosmic rays, high-energy particles accelerated by events like supernovae and black holes, constantly bombard Earth, creating particle showers in our atmosphere. We also explore gamma-ray bursts, some of the most energetic explosions in the cosmos, capable of releasing more energy in seconds than the Sun will in its entire lifetime. The episode highlights how Earth’s magnetosphere and atmosphere protect us, while noting the dangers cosmic radiation poses to astronauts and space missions. Finally, we consider how studying cosmic radiation not only reveals the violent processes of the universe but also provides crucial insights for the future of human space exploration.
