Last year, the telescope captured this The very first image Messier g 87 A glowing “obsessive” black hole in the center of the galaxy with a still image of the supermassive object object M8787 * to the scientific community and space enthusiasts. Now, more images reveal that the black hole appears to be “wandering” – a big surprise for researchers.
Freeing historic historical photo, Scientists have studied archival data sets from 2019-2013 to better understand how black holes behave. They found the presence of a constant shadow in the shape of a crescent – and noted that it has rotated significantly over the past decade.
The luminosity of the M87 appears to have faded over time, possibly due to the expulsion of a nearby object trapped in its intense gravitational pull, scientists said in a new study published in the Astrophysical Journal. A ring of gas heated up to billions of degrees, vibrating from magnetic fields, performs a kind of black hole dance that changes its appearance over time.

“Last year we saw an image of a shadow of a black hole, consisting of a bright crescent formed by hot plasma orbiting around M8787 *, and a dark central part, where we expect a black hole phenomenon horizon.” Macky Wilgus, an astronomical author at the Harvard and Smithsonian Center for Astrophysics, said in a news release. “But those results were based solely on observations made in a one-week window in April 2017, which is too short to see too many changes.”
Wandering is big news – it allows scientists to study the flow of the emergence of an object object, which is the rate at which material enters a black hole, and the relativity jet, which is the flow of that very energetic material. It is important to study the region to understand how black holes and surrounding objects interact with the host galaxy.
M87 *, located about 55 million light-years away in the constellation Virgo, has a massive mass of 6.5 billion suns. When the ring rotated, its shape did not change, and its diameter remained consistent with Einstein’s theory of general relativity, the scientists said.
“In this study, we show that the presence of normal morphology, or asymmetric ring, largely persists over a period of several years,” said Kaju Akiyama, co-author of the MIT Hestack Observatory. “This is an important confirmation of the theoretical expectations as consistency in multiple observation eras gives us more confidence than ever before about the compatibility, the nature of the M87 * and the origin of the shadow.”
The historic historical image of the supermassive black hole was captured by the Event Horizon Telescope (EHT) and released in April 2019. The image does not really show the black hole, which is known for sucking light, but its shadow, a bright orange ring of incredibly hot gas.
Scientists hope that their new findings provide a framework for further study of not only M87, but all black holes.
“These initial EHT experiments provide us with a wealth of long-term observations that the current EHT does not even match its significant imaging capabilities,” EHT’s founding director Shep Doleman said in a release. “When we first measured the size of the M87 (8) in 2009, we could not have predicted that it would give us the first glimpse of the black hole’s dynamics. If you want a black hole to evolve in a decade, there is no alternative. There is a decade of data. “
