A new study from Rice University suggests that Earth-like planets may be more common in the universe than previously thought.
The study challenges old ideas by proposing that planets form in narrow rings of material around young stars, rather than from scattered space dust.
The researchers used N-body models to simulate planet formation and found that super-Earths tend to form closer to the star, while mini-Neptunes form farther out.
The model also suggests that some Earth-like planets could potentially exist in the habitable zone, where liquid water may be present.
