Voids Made by Dying Stars Have Been Detected in Our Galaxy's Interstellar Gas

A new analysis of the tenuous gas that drifts between the stars in the Milky Way galaxy has revealed the imprint of bubbles that expand into space when a massive star goes supernova at the end of its life. These ghostly traces, scientists say, record a history of star death and the rotation of the Milky Way.The space between the stars is not entirely empty. In those gaps in space drifts gas, sometimes coming together in more diffuse clouds, mostly of atomic hydrogen.

It's the most detailed survey of its kind conducted so far, mapping not just the distribution of the galaxy's hydrogen, but its velocity as well. By combining this with a model of the Milky Way's rotation, the researchers can gauge the distance to structures in the gas.With these data, the team employed an algorithm commonly used to analyze satellite photos, teasing out fine structures in the hydrogen that would have been impossible to identify by eye.

The team interpreted these networks as the imprint of supernova feedback in the gas of the Milky Way. This, the team said, could offer a new probe for understanding the dynamical processes that shaped the disk of the Milky Way, and a tool for conducting galactic archaeology – studying the fossils of ancient processes to reconstruct our galaxy's history.
