NASA Hits Major Milestone: 6,000 Confirmed Planets Beyond the Solar System

It’s official: NASA has now confirmed 6,000 exoplanets, planets outside our solar system. We’ve made this leap in just over thirty years since the first planet around a Sun-like star was verified in 1995. We’ve watched the night sky change. Each discovery adds more worlds, some small and rocky, some giant and gaseous, many unlike anything we ever imagined. Many are still just candidates, but confirming them takes care and time.
