By playing a cosmic game of hide-and-seek, astronomers have spotted four new "mini-Neptunes" around a distant star.
The exoplanets belong to a class of worlds called mini-Neptunes, which are smaller and farther from their stars than so-called hot Jupiters, which are easier to spot because they are massive and orbit close to their host stars. Mini-Neptunes, by comparison, are much more challenging to find.
