Summarize in point-form the following text: WASHINGTON, April 13 (Reuters) - 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.

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). Make sure to only use capital letters in your entire response.
