Something strange surrounds us — an invisible bubble of million-degree plasma stretching hundreds of light-years wide. NASA calls it the Local Hot Bubble — a vast remnant of ancient supernovae that still holds our Solar System inside its ghostly shell.
In this Sleepy Scientist Stories episode, we journey through the ashes of dying stars to uncover what’s really hiding beyond our Solar System — from radioactive fingerprints in Earth’s oceans, to the mysterious tunnels of interstellar space revealed by X-ray telescopes like eROSITA and Gaia.
You’ll drift through the science of stellar death and cosmic rebirth — learning how supernova explosions not only shaped the space around us, but also created the very elements in our bones.
