Telescopes in space could have better performance, because you are not limited by atmospheric conditions for your angular resolution. But you still need a larger aperture to increase your theoretical angular resolution (see the Rayleigh criterion), and increase light gathering power.
- outworlder 7y agoCan't you have a fleet (something like StarLink, but telescopes) and have a bigger effective aperture?
- HorstG 7y agoTheoretically yes, through interferometry. But that is really difficult when there is relative motion within the constellation such as with starlink.
