The black hole on the middle of our galaxy has been in comparison with a doughnut — and because it seems, this doughnut has swirls. Scientists shared a mesmerizing new image on Wednesday, displaying Sagittarius A* in unprecedented element. The polarized mild image exhibits the black hole’s magnetic field construction as a hanging spiral.
“What we’re seeing now is that there are strong, twisted, and organized magnetic fields near the black hole at the center of the Milky Way galaxy,” Sara Issaoun, a undertaking co-leader and NASA Hubble Fellowship Program Einstein Fellow on the Center for Astrophysics at Harvard & Smithsonian, stated in a statement about the image.
The image captures what the Event Horizon Telescope collaboration calls a “new view of the monster lurking at the heart of the Milky Way galaxy.”
The doughnut analogy additionally applies to distance: Because of the Milky Way’s distance from Earth, taking a look at it from our planet is much like seeing a doughnut on the floor of the Moon.
Sagittarius A*, additionally sometimes called Sgr A*, is about 27,000 mild years from Earth. The first image of the supermassive black hole was launched two years in the past, displaying glowing gasoline round a darkish middle — and missing the element of the new image.
The supermassive black hole Sagittarius A* is seen at left, in polarized mild. The middle inset image exhibits polarized emission from the Milky Way’s middle, captured by SOFIA. The background image exhibits the Planck Collaboration’s mapping of polarized emission from mud throughout the Milky Way.

Black holes are well-known for being “effectively invisible,” as NASA says. But they dramatically have an effect on their surrounding area, most clearly by creating an accretion disk — the swirl of gasoline and materials that orbits a darkish central area.
The first image of a black hole was released in 2019, when the Event Horizon Telescope undertaking shared an image of the black hole on the middle of galaxy Messier 87 (M87), some 55 million mild years from Earth in the Virgo galaxy cluster. Although it is farther away, the black hole often known as M87* is way bigger than Sagittarius A*.
When researchers just lately in contrast views of the 2 black holes in polarized mild, they had been struck by their shared traits — most dramatically, these swirls.
“Along with Sgr A* having a strikingly similar polarization structure to that seen in the much larger and more powerful M87* black hole,” Issaoun stated, “we’ve learned that strong and ordered magnetic fields are critical to how black holes interact with the gas and matter around them.”
Side-by-side photographs of M87* and Sagittarius A* reveal that the supermassive black holes have comparable magnetic field buildings, suggesting that the bodily processes governing supermassive black hole could also be common.

On a sensible stage, the black holes do have one stark distinction: While M87* has a knack for holding regular, our Sgr A* “is changing so fast that it doesn’t sit still for pictures,” the researchers stated in their announcement.
At the time the Sgr A* observations had been captured, the EHT collaboration was utilizing eight telescopes all over the world, linking them collectively to create a planet-sized, albeit digital, instrument. The outcomes of their work had been revealed Wednesday in The Astrophysical Journal Letters.
The collaboration is slated to look at Sgr A* once more in April.
