Answer 1

Yes we are looking in the past. We see their star and by observing we found that parts of the stars have a dot like point when looking at them. Research later we could confirm that these points we saw were indeed planets moving on their lanes. The bigger and closer the planet is to it’s star, the ‘easier’ it gets to observe it.
