Our solar system lies at the center of a huge bubble in space known as the local bubble. This cavity has an extremely low particle density, at least ten times lower than the average density of the interstellar medium in our galaxy. But at the same time, it contains a thin gruel of high-temperature X-ray-emitting plasma that can rage up to a million degrees. This cavity is known as the local bubble and is home to our Sun and thousands of other neighboring stars. But how did we discover this bubble? How did it form in the first place? And most importantly, when did the Sun enter it?

The sixth episode of the Sunday Discoveries Series answers these questions along with the latest research on the formation of the Local Bubble.
