The Milky Way galaxy, once thought to have a calm history, has revealed violent past events, including the discovery of massive gamma ray structures called the Fermi Bubbles. These bubbles, originating from the central black hole, play a crucial role in understanding the galaxy's evolution and potential future events, emphasizing the importance of monitoring Sagittarius A* for insights into the Milky Way's activity.
Insights
The Milky Way, despite its overall calm history, contains a massive black hole at its center, along with smaller black holes, hot gas clouds, and massive stars, hinting at a complex and dynamic internal structure.
The discovery of the Fermi Bubbles, massive gamma ray structures formed through Inverse Compton Scattering, suggests a violent past for the Milky Way, with energy equivalent to 100,000 supernova explosions, potentially originating from a mini AGN phase near the central black hole.
