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.
ETFs explained
Exhchange traded funds are bought and sold like shares, but operate as index-tracking funds, passively following their chosen indices, such as the S&P 500, FTSE 100 and the FTSE All World, plus a vast range of smaller exchanges and commodities, such as gold, silver, copper sugar, coffee and oil.
ETFs have zero upfront fees and annual charges as low as 0.07 per cent a year, which means you get to keep more of your returns, as actively managed funds can charge as much as 1.5 per cent a year.
There are thousands to choose from, with the five biggest providers BlackRock’s iShares range, Vanguard, State Street Global Advisors SPDR ETFs, Deutsche Bank AWM X-trackers and Invesco PowerShares.

WHAT IS A BLACK HOLE?
1. Black holes are objects whose gravity is so strong not even light can escape their pull
2. They can be created when massive stars collapse under their own weight
3. Large black holes can also be formed when smaller ones collide and merge
4. The biggest black holes lurk at the centre of many galaxies, including our own
5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed

What vitamins do we know are beneficial for living in the UAE
Vitamin D: Highly relevant in the UAE due to limited sun exposure; supports bone health, immunity and mood.
Vitamin B12: Important for nerve health and energy production, especially for vegetarians, vegans and individuals with absorption issues.
Iron: Useful only when deficiency or anaemia is confirmed; helps reduce fatigue and support immunity.
Omega-3 (EPA/DHA): Supports heart health and reduces inflammation, especially for those who consume little fish.
