(click to enlarge)
High Level Science Goals:
Understand by
high angular resolution spectral imaging the details and dynamics of
heretofore unresolved objects and processes:
- Solar/Stellar
Magnetic Activity and their impact on the Climates & Habitability
of Planets and Life
- Magnetic
& Accretion Processes and their roles in the Evolution of Structure
& Transport of Matter throughout the Universe
- the close-in
structure of Active Galactic Nuclei (AGN) and their winds
