First clear picture of black hole surfaced

Until a few years ago, it was only imagined that what the superpower of the universe would look like. We are talking about black hole. Of the almighty who swallows everything. Now its picture is clear. Now we can recognize it. A team of researchers used a machine-learning technique called PRIMO to get a better picture. The researchers published the clear picture on April 13 in The Astrophysical Journal Letters.

Picture of black hole cleared through PRIMO learning machine

You might remember when astronomers first released the first image of a black hole in 2019. Its picture was captured by the Event Horizon Telescope (EHT). That image of the black hole to the world was an amazing and historic achievement. But four days ago the team of scientists gave a new look to this picture. This feat was made possible through machine learning. Now the true color of the black hole has become much clearer than before.

This black hole is 55 million light years away from us.

Scientists say that this black hole is of supermassive type, which is located in the center of a giant elliptical galaxy named Messier 87 and is 55 million light-years away from Earth. The researchers first developed a new machine-learning technique to make radio interferometry images clearer. Messier 87 extends over a radius of 25 billion miles (40 billion km).

According to lead author Leah Medeiros of the Institute for Advanced Study

With our new machine learning technique, PRIMO, we were able to achieve the maximum resolution of the current array. Since we can’t study a black hole up close, the details of an image play an important role in our ability to understand its behavior.

Todd Lauer of noIRLab reported that the scientists collected more than 30,000 simulated images of the gas accreting onto the black hole. Next, Primo looked for common patterns between the images. Then, all images were combined into a new high-fidelity image. Overall, the new and updated image was able to show details that were not visible in the original image.
