- Scientists say our galaxy’s central black hole, Sagittarius A, has finally shown signs of a wind — a 3‑light‑year, cone‑shaped cavity cleared of cold gas that points back to the black hole.
- Researchers used ALMA and NASA’s Chandra X‑ray Observatory to make the most detailed map yet and infer hot plasma sculpting the cavity — likened to a “hair dryer” blowing away colder gas.
- The outflow is a weak breeze rather than dramatic jets, showing Sagittarius A behaves like other supermassive black holes; scientists plan to map a bigger region and make a “movie” of the gas next.
