infrare/infrared

One is visible in the visible range of the spectrum and one is an infrared photon.

And people have literally searched through infrared surveys that already existed of our sky, looking for excess heat, like coming off of what would be a Dyson sphere, and put limits on it.

Yep, so this is a 63 by 63 pixel bitmap, and essentially I take that and there's actually an infrared sensor on the display that can receive data.
