The Event Horizon Telescope Collaboration achieved a 19 microarcsecond resolution observation of distant supermassive black holes.
The Event Horizon Telescope (EHT) has achieved the highest-resolution observations of black holes ever taken from Earth's surface. The EHT Collaboration, comprised of scientists worldwide, used a combination of radio telescopes to observe distant galaxies and their supermassive black holes at a frequency of around 345 GHz, equivalent to a wavelength of 0.87 mm. The new observations have resulted in a resolution as fine as 19 microarcseconds, the highest ever resolution obtained from the surface of Earth. These high-resolution images will help researchers uncover the mysteries of how black holes attract matter and launch powerful jets, and could provide insight into previously unobservable smaller, fainter, and more distant supermassive black holes.
