(a) at astronomical observatories capture light emitted by celestial bodies even better than the unassisted human eye, providing a clearer picture of our galaxy.
(a) can be used to detect different elements in the atmospheres and surfaces of planets.
(a) can be used to map mineral composition of planet surfaces.
(a) can be used to map the surfaces of astronomical objects.
(a) can be used to provide measurements of gravity fields and mass concentrations (location of areas with a lot of space objects) in space.
(a) detect the largest wavelengths.
