The first clue for caution is this should be the title: Theoretical astrophysicists have discovered that millions of planets are more habitable than we realized
The authors, led by Jérémy Leconte, a postdoctoral fellow at the Canadian Institute for Theoretical Astrophysics at the University of Toronto, built a three-dimensional climate model and found that a thin atmosphere would allow a planet to break free of rotational lockup and spin as it rotates around the star.
Scientists previously thought that only a large atmosphere could create a significant spin but, according to Leconte, thin atmospheres may have a larger rotational effect, because they allow more light from the star to reach the planet’s surface. This solar heat drives wind to create an atmospheric tide, which in turn creates a friction that causes the planet to rotate.
Don’t blast off just yet.
