The Intricate Nature of Galactic Bubbles in the Milky Way.

A new study published in Nature Astronomy has revealed that the eRosita bubbles, giant structures of high-energy gas extending above and below the Milky Way galaxy’s center, are more complex and not hotter than surrounding areas, contrary to previous assumptions. The study suggests that the bubbles originate from nuclear star-forming activity rather than a supermassive black hole. The researchers used observations made by the Suzaku satellite to analyze the properties of these bubbles and hope to use new data from other upcoming space missions to continue characterizing them.
