The Two Scientific Ways We Can Improve Our Images Of Event Horizons

In order to resolve the 'hole' in the center of this gas, the number of wavelengths that can fit across your telescope diameter must correspond to a sharper resolution than the apparent angular size of the 'hole' itself.

Tremblay et al./NASA/ESA Hubble/ALMA (ESO/NAOJ/NRAO)The largest black holes, as viewed from Earth, possess event horizons merely tens of microarcseconds (μas) in angular size.

Only the South Pole Telescope was unable to image M87, as it is located on the wrong part of the Earth to ever view that galaxy's center.
