Recent research utilizing microlensing offers new insights into exoplanets, suggesting a broader variety of planetary systems than previously recognized. While traditional discovery methods have favored planets near their stars, microlensing highlights potentially abundant rocky super-Earths at greater distances, akin to the positions of Jupiter and Saturn. This method enhances our understanding of the diversity and arrangement of distant planetary systems, emphasizing that our knowledge so far has been influenced by observational biases, including shorter orbital periods typically facilitating detection.
Microlensing events allow astronomers to discover planets in wider orbits that traditional methods overlook, revealing a diverse population of potentially rocky super-Earths.
With microlensing, researchers found evidence suggesting a substantial number of rocky super-Earths orbiting at distances akin to Jupiter and Saturn, challenging previous biases.
