Black-hole image reveals details of turmoil around the abyss
The first image of a black hole blew us away in 2019, showing a ‘ring of fire’ of radio-wavelength emissions swirling around an abyss called M87*. Now, a machine-learning algorithm maximises the resolution of the image to show a substantially thinner ring. And fresh data reveal that a stupendously bright jet of superheated matter, which was observed long before the black hole was imaged, actually emerges from the ring. Astronomers know that jets are ejected from the region surrounding black holes, but it’s still not fully understood how that happens.
