To create the first image of a black hole taken four years ago, researchers used an array of radio telescopes to collect data on light and swirling gas.
Researchers have used artificial intelligence (AI) to recreate the first image of a black hole taken 4 years ago.
This image of an AI-recreated black hole was published in Astrophysical Journal Letters on April 13.
In 2019, the first image of a black hole in the universe was released, showing a fuzzy doughnut-shaped object on fire. Here is an image of the giant black hole at the center of the galaxy Messier 87 (M87)53 million light years from Earth.

To create this image, the researchers used an array of radio telescopes to collect data on light and swirling gases. However, many gaps remain in these data.
In the new study, scientists used available data along with machine learning technology to fill in the missing pieces. The newly created image has a similar shape to the original, but the donut ring is thinner and the center is darker.
Ms Lia Medeiros, astrophysicist at the Institute for Advanced Study in New Jersey (USA) and also leader of the research team, shared: “I feel like this is really the first time I’ve seen this image.”
Building on the success of the photo, the team of scientists hopes to further research the characteristics and gravity of black holes in the future.
Madeiros added that the team plans to use machine learning to create more images of other celestial bodies, possibly including the black hole at the center of the Milky Way.
According to a study published March 28 in the journal of the Royal Astronomical Society, British astronomers have discovered one of the largest black holes ever seen using a new technique, raising hopes that there will be more. will be discovered by scientists in the near future.
The newly discovered black hole has a mass 30 billion times that of the Sun and is about 2 billion light years from Earth.
It is one of the four largest black holes ever observed and the first black hole observed using the gravitational lensing technique, in which light transmitted from a distant galaxy is amplified and directed inward , representing the image of a giant black hole.
The lead author of the study, astronomer at the University of Durham (UK), Mr James Nightingale, describes this process as “similar to light shining through the bottom of a wine glass” and will allow astronomers to explore and destroy black holes in 99% of cases. other currently inaccessible galaxies.
In this latest discovery, the researchers also used computer simulations and images from the Hubble Space Telescope to confirm their findings, as well as to rule out possible factors causing misleading results such as excessive dark matter concentration.
Mr Nightingale said the enormous size above is consistent with estimates of a black hole at the center of the host galaxy.
It may also be the largest black hole ever recorded, but it is difficult to confirm this with certainty due to differences in detection techniques and associated uncertainties.
According to researcher Nightingale, the space landscape is also about to change significantly.
The European Space Agency is expected to launch the Euclid Space Telescope mission in July 2023, which is expected to usher in an “era of big data” by creating a giant map of the universe at large scale and high resolution.
Mr. Nightingale hopes that over the next 6 years, Euclid can help discover thousands of still-hidden black holes.
Previously, the US Aeronautics and Space Administration (NASA) said on February 22 that using the Chandra X-ray Observatory, the agency discovered two giant black holes in a dwarf galaxy about to to collide.
NASA emphasizes that this collision can provide scientists with important information about the development of black holes in the early universe.
NASA said that, by definition, dwarf galaxies contain stars with a total mass about 3 billion times less than that of the Sun.
Astronomers have long hypothesized that dwarf galaxies merged relatively early, particularly in the early universe, to give rise to the larger galaxies we see today.
However, current technology cannot observe early dwarf galaxy mergers because images taken from long distances are very faint.
