The Milky Way's eROSITA bubbles are large and distant

In 2020, astronomers discovered a large hourglass-shaped structure in or near the center of our Milky Way galaxy. Dubbed "eROSITA bubbles," there have been a few different hypotheses proposed to explain their precise nature. Now, a research team of scientists from China and Europe has constructed a high-resolution map of the region and found evidence that two of the most prominent features are not independent.
