Ice in a million-degree Fermi bubble reveals the Milky Way’s recent eruption
2025-07-09
Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds — or Fermi bubbles — at the Milky Way’s center. The finding challenges current models of Fermi bubble formation and reveals that the bubbles are much younger than previously estimated. “The Fermi bubbles are enormous structuresContinue Reading
