Galactic planetary science

摘要: Planetary science beyond the boundaries of our Solar System is today in its infancy. Until a couple decades ago, detailed investigation planetary properties was restricted to objects orbiting inside Kuiper Belt. Today, we cannot ignore that number known planets has increased by two orders magnitude nor these resemble anything but present own System. Whether this fact result selection bias induced kind techniques used discover new planets—mainly radial velocity and transit—or simply proof rarity Milky Way, do not know yet. What clear, though, failed be paradigm only Galaxy even ‘just’ solar neighbourhood. This finding, although unsettling, forces us reconsider knowledge under different light perhaps question few theoretical pillars on which base current ‘understanding’. The next decade will critical advance what should call Galactic science. In paper, I review highlights pitfalls topic elaborate how might arguably evolve decade. More critically, identify mandatory scientific technical steps taken fascinating journey remote exploration Galaxy.
