Humanity'sfirst image of a black hole has gotten a makeover.

The iconic picture of the supermassive black hole at the center of Messier 87,a giantgalaxy sitting 53 million light-years from Earth in the "nearby" Virgocluster,was first released in 2019. The M87 black hole appeared as a flaming, fuzzy doughnut-like object emerging from a darkbackdrop but now we have a sharper look.

The new image,published Thursday in a Astrophysical Journal Lettersstudy,gives us a refined look at the black hole which now looks like a skinner, bright orange ring with a clearer dark center.

According to the study, the image was reconstructed using new machine-learningtechnology called PRIMO. Scientists relied on the same data that was used to create the 2019 image originally obtained by anEvent Horizon Telescope collaboration in 2017.

In 2017, a network of radio telescopes around the world formed "an Earth-sized virtual telescope with the power and resolution capable of observing the 'shadow'of a black holes event horizon," the National Science Foundation's NOIRLab notes.

While this allowed scientists to see incredible details, gaps remained. PRIMO has helped fill in the missing pieces.

"Since we cannot study black holes up close, the detail in an image plays a critical role in our ability to understand its behavior,"Lia Medeiros, an astrophysicist at the Institute for Advanced Study inNew Jersey andlead author of Thursday's study, said in theNOIRLab press release.

"The width of the ring in the image is now smaller by about a factor of two, which will be a powerful constraint for our theoretical models and tests of gravity."

The machine learning technique also brings the possibility of further work on other images of celestial objects, NOIRLab notes includingSagittarius A*,the black hole at the center of our Milky Way galaxy. Astronomers revealedan image ofSagittarius A* in May 2022, which was also captured usingEHT data.

"The 2019 image was just the beginning,"Medeiros said. "If a picture is worth a thousand words, the data underlying that image have many more stories to tell. PRIMO will continue to be a critical tool in extracting such insights."
