Event Horizon Telescope improves black hole imaging resolution

The Event Horizon Telescope (EHT) has achieved a resolution of 19 microarcseconds by conducting very long baseline interferometry at a new radio wavelength of 0.87mm, improving observational acuity by 50%. This advancement could lead to sharper images of black holes, including Sagittarius A* and M87*, and enhance understanding of their properties. The findings were published on August 27 in The Astronomical Journal.
