The author of this paper Prof. Kipping has a good video on the concept. See his YouTube channel Cool Worlds.
To summarise, you put a telescope beyond the orbit of the moon and use the earth's atmosphere as a lens
- sp332 4y agoThe abstract here says 85% of the distance to the moon. I imagine it would be difficult to maintain an orbit at that distance.
- skykooler 4y ago85% is the minimum distance, but lens quality improves the further out you go because the lensing region moves up into the stratosphere so you get less distortion from clouds.
- stripykitteh 4y agoApparently at the distance of the Hill Sphere of the Earth (about 4 times the Moon's orbital distance) the effect would still work.
- PaulHoule 4y agoThe moon's gravity is in play so the orbit might not be so simple, but there are all sorts of "halo orbits", orbits around the L4 and L5 points, etc. It seems to me though that the Earth's atmosphere is always going to be "lit up" one way or another by some phenomenon like the Aurora Borealis, scattering and various sorts of skyglow, so there will be some background, but maybe it is not that bad.
