eROSITA All-Sky Survey has created a 3D map of the solar system's Local Hot Bubble .

The bubble is a cavity of low-density gas that was first suggested to explain background measurements of relatively low-energy, or "soft," X-rays.

The researchers also found what seems to be an "interstellar tunnel," a channel between stars directed towards the constellation Centaurus.

These phenomena are collectively referred to as "stellar feedback," and they are believed to sweep across the Milky Way.

In addition to the 3D map of the LHB , the team also created a census of supernova wreckage, superbubbles, and dust.

This included another previously known interstellar medium tunnel called the Canis Majoris tunnel.
