In 2019, there was a big buzz that with the help of the Event Horizon Telescope (EHT), scientists made a recording of a black hole. This was important because black holes are known to have such strong gravity that even light cannot escape from them. That is why it is not even possible to observe what is happening beyond the event horizon.
The virtual telescope compiles the image from data recorded by stations located in different parts of the Earth. The result is as if scientists were looking through a planet-sized telescope. First, images were taken of the supermassive black hole at the center of the galaxy called M87, and in 2022, a similar image was taken of Sagittarius A* at the center of the Milky Way.
While this performance is impressive in itself, we will soon see more historic images: experts are working to ensure that the Event Horizon Telescope will produce 50 percent sharper images in the future, writes Interesting engineeringAccording to the report, the EHT has already been able to detect light from distant galaxies at a frequency of 345 GHz, which corresponds to a wavelength of 0.87 mm.
Alexander Raymondpublished in the Astronomical Journal Publishing According to its author, you can really understand what this means if you add that the first published image of a black hole was taken at a frequency of 230 GHz. The specialist believes that clearer images could confirm many previous assumptions about black holes and perhaps see something they were not aware of until now. He adds that it is not yet known when the first clearer image of a black hole might appear hvg.
