New research has a duo of scientists unsure that humanity’s first-ever exomoon detections N are accurate. In fact, the same findings also showed that exomoons in general may only show themselves if they are extremely large. The new research demonstrates that while there is no reason to suggest moons aren’t orbiting worlds in other planetary systems, finding them is a tricky business. In the three decades since the first detection of an extrasolar planet, or ‘exoplanet’, the catalogue of worlds around other stars has burgeoned, with well over 5,000 examples confirmed to date.
