Location of the validated and non-validated planet candidates in the period-radius diagram. The red polygons show the non-validated candidates, the dark-green polygons show the validated planets, and the orange polygons show the candidates which validation status is only suggestive. The grey circles show the population of all validated planets with radius uncertainties below 10%, and the blue circles highlight those planets orbiting M-type stars. The blue-shaded region shows the Neptune desert as defined by Mazeh et al. (2016). However, in recent years, this region has become more populated, and the boundaries of the desert do not match the typical definitions any longer. Thus, we suggest the pink-shaded area, where the scarcity of planets is noteworthy, as an updated definition of the Neptune desert based on the current population of known planets. -- astro-ph.EP

The TESS mission searches for transiting exoplanets by monitoring the brightness of hundreds of thousands of stars across the entire sky.
