NASA’s Proposed EVE Mission Aims to Solve the Radius Valley Mystery
A debate has been raging amongst planetary scientists for over a decade - why are there so few exoplanets with a radius of about 1.8 times that of the Earth? Exoplanets are currently largely grouped into two distinct groups - “super Earth” are below that size and have rocky interiors, whereas “Sub-Neptunes” are above that size limit and appear “puffier.” But we don’t really understand what about the path of planetary evolution forces this bifurc…
NASA has presented the proposal for the Early eVolution Explorer (EVE) mission, which aims to investigate the scarcity of exoplanets with radii approximately 1.8 times larger than Earth's. This research seeks to understand the reasons behind the observed bifurcation in planetary evolution, where exoplanets are classified into two main categories: super-Earths and sub-Neptunes. The main objective of the EVE mission is to elucidate the phenomenon …
