The first image of a black hole captured four years ago revealed a fuzzy, fiery doughnut-shaped object.
Now, researchers have used artificial intelligence to give that cosmic beauty shot a touch-up.
The updated picture, published on Thursday in the Astrophysical Journal Letters, keeps the original shape, but with a skinnier ring and a sharper resolution.
The image released in 2019 gave a peek at the enormous black hole at the centre of the M87 galaxy, 53 million light-years from Earth. A light-year is 9.3 trillion km.
The image was made using data gathered by a network of radio telescopes around the world, showing swirling light and gas.
But even with many telescopes working together, gaps remained in the data.
In the latest study, scientists relied on the same data and used machine learning to fill in the missing pieces.
The resulting picture looks similar to the original, but with a thinner “doughnut” and a darker centre, researchers said.
“For me, it feels like we’re really seeing it for the first time,” said lead author Lia Medeiros, an astrophysicist at the Institute for Advanced Study in New Jersey.
By having a clearer picture, researchers hope to learn more about the black hole’s properties and gravity in future studies.
Ms Medeiros said the team plans to use machine learning on other images of celestial objects, including the black hole at the centre of our Milky Way galaxy.
