Has anyone tried to collect more light with a longer exposure? The image posted is exposed for the surface... Is there absolutely no light in the holes or is it only relative to the light on the surface?
Couldn't we put a light in one of these holes in three years? If we really want to?

Can anyone tell me what the scale of the image is? How high are those gas jets we see in it?
TIA, ean
