Astronomers analyzing 13 years of data from NASA’s Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy. “It is a completely serendipitous discovery,” said Alexander Kashlinsky, a cosmologist at the University of Maryland and NASA’s Goddard Space Flight Center in Greenbelt, who presented the research at the 243rd meeting of the American Astronomical Society in New Orleans.

Some 5 million years ago, a black hole eruption in the galaxy NGC 4945 set off a star-formation frenzy and shot a vast cloud of gas into intergalactic space. Watch and learn how two X-ray telescopes revealed the story. Credit: NASA’s Goddard Space Flight Center |
Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies. The X-rays outline giant clouds of cold gas in the nearby spiral galaxy NGC 4945. The gas appears to have blasted through the galaxy after its central supermassive black hole erupted some 5 million years ago. Read more » |
