Jona Jaupi , Technology and Science Reporter Published : 16:42, 4 Aug 2023 Updated : 16:47, 4 Aug 2023 RESEARCHERS have uncovered radio signals that are believed to be emerging from a black hole. The object, called GRS 1915+105, consists of a regular star orbiting a stellar black hole. 1 Researchers have uncovered radio signals that are believed to be emerging from a black hole Credit: Getty Stellar black holes form when the center of a very massive star collapses in upon itself . Now, scientists noticed some changes in the jet material that is frequently ejected from the black hole. It's normal for material that derives from stars to get consumed by nearby black holes. Black holes typically consume most of the material, but some of it gets turned into jet streams that are spit back out. However, researchers have now noticed "periodic changes in the jet occurring within a fraction of a second," Live Science noted. The changes were observed by the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) in China. Researchers said that the changes could be explained by the fact that the black hole's rotation is misaligned with its accretion disk. An accretion disk is a flattened or elliptical structure that forms when space material is pulled toward a black hole. "That could be causing the jet to wobble almost like a cosmic spinning top," Live Science explained. "When the jet points away, its energy drops. A fraction of a second later, it returns to normal when the system rotates back," it added. "The peculiar signal has a rough period of 0.2 seconds or a frequency of about 5 Hertz," Wei Wang, a professor of astrophysics at Wuhan University in China and the lead author of the study, said in a statement . "Such a signal does not always exist and only shows up under special physical conditions," Wang added){kind=link}
