Event Horizon Telescope Captures First Black Hole Image

The Event Horizon Telescope, a collaboration of radio telescopes throughout the world that work in unison to capture images of supermassive black holes, just achieved its best picture yet. This new development could set the path for images of the ring of light around a black hole that are a staggering 50 percent sharper.

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the centre of our Galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of Sagittarius A*. This image shows the polarised view of the Milky Way black hole. The lines overlaid on this image mark the orientation of polarisation, which is related to the magnetic field around the shadow of the black hole.
