The EHT (Event Horizon Telescope) was scheduled to release images of a black hole on Wed 10th April, and they didn't disappoint.

Earthrise is possibly one of the most significant images ever shot in the history of humankind ... it showed us how small we areas a community/civilisation.
'Black Hole' must surely come close to a similar level of significance.
Seeing the unseeable for the first time, confirmation of their existence, confirmation on the theories of how they're expected to behave .. etc.
FWIW: the actual black hole itself is supposedly larger than the solar system!
