Astounding we can now see things at those kinds of distances.
Also interesting is that most of the planets being found appear to belong to dwarf stars; our situation is unusual.
Its believed that 80% of the stars in the universe are red dwarfs and are only visible to us in infrared light. Seems like I read that we discovered one only about 6 light years away a few years back.
Considering the possibility that red dwarfs may last for as much as a trillion years (yes with a T) planets around them would be good places for life to exist. However the planet needs to be so close as to be tidally locked which presents problems for life. Still, the variables are nearly infinite so who knows.
Sol is classified as a yellow dwarf.
