Scientists have discovered a tunnel in the Local Hot Bubble, a low-density gas region near our solar system, that could lead to other parts of the Milky Way. The Local Hot Bubble is a vast volume of hot gas extending from the Sun and beyond, created by a supernova millions of years ago.
New data from the eROSITA X-ray telescope has revealed the tunnel’s features, including its growth rate and shell structure. This tunnel effectively links the Local Hot Bubble to another ‘superbubble’ in the Centaurus constellation.
The discovery provides valuable insights into the Milky Way’s structure and evolution. Supernovae and stellar winds play a crucial role in shaping the galaxy by blowing cavities in cool gas clouds, contributing to its expansion, and maintaining networks of gas conduits.
Further research using advanced facilities like the eROSITA X-ray telescope is helping scientists better understand the galaxy’s dynamics and forces. The discovery paves the way for unlocking the mysteries of interconnected structures in the Milky Way, shedding light on how our solar system fits into this vast, dynamic system.
