The Spinning Supermassive Black Hole: Unlocking the Secrets of M87*

An Image that Changed Everything

Once just a fuzzy orange donut, the supermassive black hole M87* captured the world’s attention in 2019. It became the first black hole to be imaged, showcasing its mysterious beauty. With the help of AI technology, the image was further refined, revealing a slim, elegant ring. Now, in an exciting update, scientists have confirmed that M87* is not only a static void but a spinning cosmic entity.

A Network of Eyes on the Sky

For the past twenty years, a network of radio telescopes has been aimed at the heart of the Messier 87 (M87) galaxy, located 55 million light-years away in the constellation Virgo. These powerful instruments have been focused on studying the black hole known as M87*. One of the most fascinating features of this black hole is the strong jet of radiation and particles that burst from its poles. Scientists have now discovered that this relativistic jet swings back and forth like a pendulum on an 11-year cycle. This swinging motion is believed to be the result of gravitational interactions between the spinning black hole, which weighs an astounding 6.5 billion times more than the sun, and the surrounding disk of material. This groundbreaking finding provides unequivocal evidence for the spin of M87*.

A Thrilling Discovery

Cui Yuzhu, a researcher at Zhejiang Lab in China and the lead author of the new study, expressed excitement over the significant finding. “We are thrilled by this significant finding,” Yuzhu said. To uncover the 11-year swing period of the jet, the research team meticulously analyzed high-resolution data spanning two decades, unraveling the key information piece by piece.

Unlocking the Mysteries of Black Holes

The new study reveals that the jet of M87* changes its direction by approximately 10 degrees every 11 years. These results align with theoretical supercomputer simulations and offer valuable insights into the formation and evolution of black holes throughout the universe. In 2019, astronomers observed wobbling jets emanating from a black hole much closer to Earth, only 8,000 light-years away. These jets oscillated over shorter time periods, only a few minutes, making them the fastest movements of their kind ever recorded. However, the swinging jets of M87* occur over a much longer timeframe, yet they still comply with Einstein’s predictions in his theory of general relativity.

The Dance of Spacetime

As per Einstein’s theory, the massive spinning black hole twists the fabric of space and time surrounding it, a phenomenon known as frame-dragging. The team’s study highlights this effect as the spin axis of the black hole does not perfectly align with the rotation axis of the surrounding accretion disk. The slight misalignment causes the black hole’s jets to wobble subtly, and this oscillation was precisely measured in the study.

Unraveling the Secrets

The mechanisms responsible for the spin of black holes remain a mystery to scientists. A leading theory suggests that smaller black holes form by devouring matter from a surrounding accretion disk, resulting in rapid spin. Over time, these smaller black holes merge and collide to create supermassive black holes. The spin rates of black holes of varying sizes need to be studied to validate this hypothesis, and the latest findings may be a step towards that goal.

This groundbreaking research was published in the journal Nature on Wednesday (Sept. 27).

Summary: Study Confirms: Humanity’s First-Ever Black Hole Image Proven to be Spinning

The supermassive black hole M87*, which was the first to be imaged in 2019, has now been confirmed to be spinning. The announcement came on September 27th, but the exact speed of its spin is still unknown. Scientists believe that the gravitational interactions between the black hole and the disk of material around it are responsible for the swinging jet observed. This discovery provides evidence for the black hole’s spin and sheds light on the formation and evolution of black holes in the universe.
