Ground-based optical observations did not shed much further light on Mercury, but radio astronomers using interferometry at microwave wavelengths, a technique that enables removal of the solar radiation, were able to discern physical and chemical characteristics of the subsurface layers to a depth of several meters.

Lurrean oinarritutako behaketa optikoek ezin zuten askoz gehiago argitu Merkuriori buruz, baina irrati-astronomian, interferometria eta mikrouhinak erabiltzen gainazaleko geruzen eta hainbat metroko sakonerako ezaugarri fisiko eta kimikoak zehazteko gaitasuna zuten, uhin-luzera horietan eguzkiaren erradiazioa kentzen baita.
