What would Earth look like from the James Webb telescope if it were to look back rather than outwards? It'll be nearly a million miles away soon, does that make us just a spec?
The boring answer is that the Earth gives off so much infrared energy that it would totally burn out the detectors of the telescope and with the Sun being that way as well it would totally destroy the telescope.
If we ignore that then it would see a red spec which it could then decode into the various components of the atmosphere using spectrography.
I'm not sure on what the actual size of the dot would be in real-terms.
