SummaryAfter more than 50 years of searching, scientists have found evidence of wind from Sagittarius A*, the supermassive black hole at the center of our galaxy.Using advanced radio telescopes in Chile, the researchers mapped cold gas around the black hole and identified a cavity about 3 light-years long.The discovery may solve a long-standing mystery about why our closest black hole appeared to lack the outflows observed from supermassive black holes in other galaxies.AI-generated summary was reviewed by a CNN editor.Scientists say they have detected evidence of cosmic-scale wind coming from a supermassive black hole at the center of our galaxy, potentially solving one of the longest-standing mysteries in astronomy.Sagittarius A*, a gigantic black hole with the mass of about 4 million suns, has puzzled the scientific community formore than 50 years. The laws of physics dictate that, like all black holes, the object should not just consume material but also expel some in the form of wind or jets. However, Sagittarius A* has been strangely quiet. Despite decades of searching, scientists could only gather clues of wind eruptions dating back more than 20,000 years but none more recent.“This is our closest and best studied black hole,” said Mark Gorski, a research assistant professor at Northwestern University in Evanston, Illinois. “It’s the one we can resolve and see all of the physics around it, and yet it didn’t seem to have a wind. Every black hole in the universe behaves in this one way, but the one that’s closest to us is different. That was a huge problem.”Now, after five years of observations, Gorski and Lena Murchikova, an assistant professor of physics and astronomy at Northwestern, believe they have found signs of the missing wind. The duo created a highly detailed image of the black hole’s surrounding area. Within the image, Gorski and Murchikova spotted a large, cone-shaped cavity devoid of cold gas.The feature could only have been sculpted by a wind of h

摘要经过 50 多年的搜索，科学家们发现了来自银河系中心超大质量黑洞人马座 A* 存在风的证据。研究人员利用智利先进的射电望远镜绘制了黑洞周围的冷气体图，并识别出一个约 3 光年长的空腔。这一发现可能解决了一个长期存在的谜团，即为什么我们最近的黑洞似乎缺乏从其他星系的超大质量黑洞观测到的流出物。人工智能生成的摘要是
