The 2019 release of the first image of a black hole was hailed as a significant scientific achievement. But truth be told, it was a bit blurry — or, as one astrophysicist involved in the effort called it, a “fuzzy orange donut.” Scientists on Thursday unveiled a new and improved image of this black hole — a behemoth at the center of a nearby galaxy — mining the same data used for the earlier one but improving its resolution by employing image reconstruction algorithms to fill in gaps in the original telescope observations. From a report: Hard to observe by their very nature, black holes are celestial entities exerting gravitational pull so strong no matter or light can escape. The ring of light — that is, the material being sucked into the voracious object — seen in the new image is about half the width of how it looked in the previous picture. There is also a larger “brightness depression” at the center – basically the donut hole – caused by light and other matter disappearing into the black hole.
The image remains somewhat blurry due to the limitations of the data underpinning it — not quite ready for a Hollywood sci-fi blockbuster, but an advance from the 2019 version. This supermassive black hole resides in a galaxy called Messier 87, or M87, about 54 million light-years from Earth. A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). This galaxy, with a mass 6.5 billion times that of our sun, is larger and more luminous than our Milky Way.
