Event Horizon Telescope
Few objects in space captivate us like black holes—but they’re more than just mind-boggling objects in the sky. They’re also places where gravity is so extreme that it tests the limits of general relativity, and the effects of smaller-scale quantum forces kick in. Scientists around the world have essentially turned planet Earth itself into a telescope by linking eight observing facilities (and soon more) together to get the first image of a black hole’s shadow, in this case the shadow cast by the black hole at the center of galaxy M87. The researchers aren’t done yet: We should soon see an image and maybe a movie of the black hole at the center of our own galaxy.
