Astronomers detect more mystery radio bursts from beyond the Milky Way
Sure enough, astronomers have discovered even more of those mysterious fast radio bursts from outside the Milky Way galaxy. Scientists using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) telescope have detected 13 different radio bursts, including six repeat bursts from the same location in a galaxy 1.5 billion light years away. Each of those bursts represents about 25 million times more energy than the Sun, and they were collected at the lowest frequencies yet (400MHz to 800MHz).
Scientists trace a cosmic radio burst to its home galaxy
Fast radio bursts in space have confused the astronomy community for years. What causes them, and where do they come from? At last, researchers are getting some answers. For the first time, scientists have traced one of these bursts back to its home galaxy. They first used the Karl G. Jansky Very Large Array radio telescope to pinpoint the object's exact location, and then used the Gemini North telescope to create an image of that patch of sky. The most surprising part isn't how they did it, though -- it's where the radio blasts are coming from.
