Abstract:
When
Galileo Galilei pointed his telescope toward Jupiter in 1609 and
discovered what we now call the Galilean moons, he did not realized that
he had just established a new research field in astronomy. In the past
four centuries, planetary astronomy, the study of our solar system
bodies using telescopes, has increased our knowledge of the environment
of Earth, the evolution of the planets, the origin of comets and
asteroids and the formation of our solar system. Space exploration
accelerated planetary astronomy in the 1960s by allowing planetary
scientists to access in-situ and detailed data. In this talk, I will
discuss the contributions of telescopic observation over the past 50
years to planetary science, particularly the recent developments like
adaptive optics which renewed interest in ground-based observations of
planets. I will explore the contribution of all-sky surveys like
Pan-STARRS and LSST, which provide several terabytes of data a week,
changing radically the way we do astronomy. Looking to the future of
space-based astronomy, I will consider whether the James Webb Space
Telescope and ATLAST are potential successors to the successful Hubble
Space Telescope. Finally I'll explore the way in which specialized
low-cost telescopes designed to search and study exoplanets, planets
around other stars, constitutes a paradigm shift in our field.
