Due to computer simulations and machine learning, the original iconic image of a black hole
which resembled a fuzzy, orange donut, has been sharpened up to a fiery ring.
Nothing, not even light, can escape from the dark interior of this ring of hot gases because there is such a strong gravitational pull there.
The upgraded image gives it a much larger and darker appearance, according to a recent report in The Astrophysical Journal Letters.
The black hole depicted in the image is the M87, a sizable one estimated to be 6.5 billion times as massive as the sun and located 55 million light years away.
This is the black hole that a global network of telescopes observed in 2017.
The international EHT team announced they had captured the first image of M87 two years later amid great fanfare.
