Astronomers Uncover Mysterious 'Interstellar Tunnel' Near Solar System

Astronomers using the eROSITA space telescope have discovered an 'interstellar tunnel' towards the constellation of Centaurus, potentially linking our Local Bubble to a neighboring superbubble. This tunnel, filled with hot plasma, was identified through improved sensitivity in X-ray mapping, revealing a gap in the cooler interstellar medium. The discovery adds complexity to our understanding of the Local Bubble's formation, believed to be shaped by supernova explosions. Further studies are needed to clarify the tunnel's properties and its connection to the Loop I superbubble.
