Astronomers Discover Interstellar Tunnel in Local Hot Bubble

New research reveals a mysterious tunnel in the Local Hot Bubble, suggesting connections to a larger network of interstellar structures.

The Local Hot Bubble (LHB) is a region of low-density, hot gas surrounding the Solar System, identified by its X-ray emissions.
Using the eROSITA X-ray telescope, scientists created a detailed 3D model of the LHB, revealing an asymmetrical temperature gradient.
A newly discovered interstellar tunnel points towards the constellation Centaurus, possibly linking the LHB to another low-density bubble.
The tunnel's existence supports theories of a network of hot bubbles and tunnels throughout the galaxy, possibly formed by supernovae.
The findings provide a clearer understanding of the LHB's structure and its place in the Milky Way, offering insights into our galaxy's history.
