"Surprising Radio Signal and Cosmic Smoke Signals: Unveiling Mysteries of the Universe"

Astronomers have observed periodic changes in a jet of highly magnetic plasma emitted by a small black hole known as GRS 1915+105. The changes, detected by China's FAST telescope, suggest that the black hole's rotation may not be aligned with its accretion disk, causing the jet to wobble. This peculiar signal, with a frequency of about 5 Hertz, has never been seen before in radio waves from a black hole. The observation of these changes in a microquasar like GRS 1915+105 could provide insights into the feeding habits of smaller black holes and the physics of black hole systems. The exact cause of these oscillations remains unknown, but continued observations may help unravel this mystery.
