Black holes and event-horizon science
Imaging horizons, photon rings, accretion flows, and jet-launching regions in nearby supermassive black holes.
Science case
Science enabled by extreme angular resolution beyond Earth.
A future space array could extend high-resolution astronomy beyond the constraints of Earth-sized baselines and atmospheric transparency.
Relativistic jets
Resolving jet formation, collimation, magnetic structure, and particle acceleration close to compact objects.
Star and planet formation
Studying compact structures in disks, gaps, rings, and embedded regions where planets may form.
Evolved stars and masers
Mapping small-scale structure, winds, and maser emission around late-stage stars.
Astrometry and reference frames
Exploring precision astrometric applications enabled by long baselines and stable calibration.
Discovery space
Opening a regime of angular resolution where unexpected compact phenomena may become observable.
