alt Hacker NewsTitle doesn't match submission: it's not really a "coordinate" in 3D space, you "adopt" a pixel from the early imagery taken by the Nancy Grace Roman Space Telescope.
Maybe that can be reverse-projected back to something like a coordinate (if you know the distance), but it's not the same thing.
It's a coordinate on the celestial sphere, which is just as good a coordinate as anything else. Now, if the title had said something like "place" you might have a case that the expectation is that a specific spacetime point is being defined.
