New 3D Map of Local Hot Bubble Reveals Interstellar Tunnel to Superbubble

Using data from the eROSITA All-Sky Survey, astronomers mapped the Local Hot Bubble in 3D, finding a new interstellar tunnel leading towards Centaurus. This tunnel may link the bubble with another galactic superbubble, hinting at a broader network of gas corridors. The eROSITA data also unveils temperature variations within the bubble, supporting theories of supernova...
