Exoplanet Discovery Database ExoFOP Reaches 1 Million Files And Counting
Discovering an exoplanet doesn’t mean having one, definitive eureka moment. Instead, it requires multiple observations, sometimes from multiple observatories, and the scientific community coming together in agreement to finally confirm […]
