Understanding our place in the Milky Way: Insights into the local bubble

Understanding our place in the Milky Way: Insights into the local bubble PD Dr Philipp Girichidis, Prof Dr Ralf S Klessen and Dr Stefan Reissl at Heidelberg University’s Centre for Astronomy provide insights into our place in the Milky Way and the Local Bubble. The region of the Milky Way in which the solar system resides is far from uniform. We are embedded in a low-density cavity known as the Local Bubble, a structure several hundred light-years across that has been shaped by the cumulative action of multiple supernova explosions over the past 10-15 million years.
