Fomalhaut-B is the first exoplanet directly imaged whose orbit around its host star is confirmed by direct obs?

All the ones we are ever likely to see do, but only because we rely on the proximity of stars to detect them. It's quite possible that planets have been ejected out of our own Solar System in the ancient past, but we have no way of detecting cold dark things that are floating through cold dark space, and quite possibly never will.

Depends how you define exoplanet. Planet originates from the Greek for "wanderer" so from a literal perspective exoplanets only float around... However we have simulations that show planets being flung from their orbits, and with the billions of stars and planetary bodies that exist, it would be incredibly unlikely that no "floating" exoplanets exist. So to answer your question, yes it is incredibly likely that free-floating exoplanets exist, however they are incredibly hard to detect.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
