There’s also a ghost in the movie, I think — at least, there’s a heavy hinge that shouldn’t be able to open without a spectral nudge.

What’s left is a spectral scene, ghosted by the limitations of old black-and-white photographic technology and further heightened by the uneven glow generated by the camera’s flashbulb.

Future observations by the James Webb Space Telescope should also be able to tell us what the planet is made up of, using something called spectral imaging.
