Event Horizon Telescope CollaborationA telescope's resolution, meanwhile, is fundamentally determined by how many wavelengths of light fit across its physical diameter. NRAOAt the Event Horizon Telescope's maximum baseline and wavelength capabilities, it will attain resolutions of ~15 μas: a 33% improvement over the first observations.

NASA/JPL-CaltechWith both frequency and baseline improvements, we could reach ~0.05 μas resolution: 440 times sharper than our first event horizon image. Event Horizon Telescope collaboration et al.
