One of the most important characteristics of an alien planet is
whether or not it falls into what's called the habitable zone — a
Goldilocks-like range of not-too-close, not-too-far distances from the
parent star that might allow the planet to host life.
Now scientists have redefined the boundaries of the habitable zone for alien planets,
potentially kicking out some exoplanets that were thought to fall
within it, and maybe allowing a few that had been excluded to squeeze
in.
