Scientists check their work and confirm it with update on iconic black hole image
And find they were right all along
Scientists have confirmed the accuracy of the iconic black hole image produced by the Event Horizon Telescope (EHT) array in 2019. A team of four Australian researchers used a new machine learning algorithm to process the same data, and their results matched the original image. The 2019 EHT image was created by combining data from eight telescopes around the world, including Chile, the US, and Antarctica.
The researchers employed a method called closed triplets, using three telescopes to correct errors and reduce inaccuracies. The new image, published in Nature, preserves the distinctive red ring shape around the black hole M87. Dr. Samuel Lai, a postdoctoral fellow at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Western Australia, expressed relief at confirming the accuracy of the original image.
He compared the challenge of photographing a black hole to attempting to capture a doughnut on the Moon from Earth. EHT director Laurent Loinard welcomed the independent validation, stating that the new study's findings align well with the EHT Collaboration's published results, confirming the accuracy of their groundbreaking image.
