It notes that computer simulations of planet information were used by Javiera Guedes, UCSC graduate student, and his team to show that terrestrial planets could have formed around the star Alpha Centauri B and to be orbiting in the habit...

Light travels from themoonto our eyes in about 1 second, which means the moon is about 1 light-second away. Sunlight takes about 8 minutes to reach our eyes, so thesunis about 8 light minutes away. Light fromAlpha Centauri, which is the nearest star system to our own, requires roughly...

That means it's hard, for now, to understand conditions like the weather, temperatures and surface features of these alien worlds — and to know whether these planets truly have the right conditions for life. "We can only say that a planet is the right size and in the right orbit for ...
The size of the universe and its age must be large enough…we need a sufficiently old universe for second generation stars to come into existence and then for planets to have a stable life for long enough that evolution could lead to the emergence of intelligent life. Thus the universe must...
