However, it's not completely nonsense, either, in that the theoretical studies that led to the 1970s prediction of CFCs damaging the ozone layer -- prior to the observational discovery of the Antarctic ozone hole -- did involve some inspiration from theoretical studies of possible chemical reactions in the ...

This isn't an easy question to answer as there are many aspects to consider. The brighter the star, the smaller the relative photon noise is at the telescope, so it is more difficult to detect transits from distant stars. That being said, the main factor is the planet radius, as we look at flux differences from out and in transits. Thus, we can usually ...
