Ultimately, the technique will be used to create maps of exoplanets with the ELTs, and search for their exomoons. WebbAstrometry is one of the most sensitive methods for detection of extrasolar planets. Unlike transit photometry, astrometry does not depend on the distant planet being in near-perfect alignment with the line of sight from the Earth, and it can therefore be a applied to a far greater number of stars. glass beer can cups bulk
