Early in its mission, Kepler managed to find some tantalizing worlds, a handful of supersize cousins of Earth, most of them in clement orbits around smaller, cooler, quieter stars than the sun called M and K dwarfs, but all the setbacks made finding smaller Earth - sized planets around sun - like G stars a very tall order.

The size of the circles represents how easy the planets are to find.

The researchers found that whether a polar cyclone forms depends on two parameters: the energy within a planet's atmosphere, or the total intensity of its thunderstorms; and the average size of its thunderstorms, relative to the size of the planet itself.

Researchers have already found hundreds of similarly sized planets, and many appear to be far better candidates for hosting life than the one around Proxima Centauri, called Proxima b.
