Phys.org / Radio telescopes on the moon could let us observe dozens of black hole shadows

We now have direct images of two supermassive black holes: M87* and Sag A*. The fact that we can capture such images is remarkable, but they might be the only black holes we can observe. That is, unless we take radio astronomy ...
