Evidence for Active Hollows Formation on Mercury

by Jason Major December 19, 2012

MESSENGER targeted-observation image of the interior of Eminescu crater A recent image acquired by NASA’s MESSENGER spacecraft shows the interior of Eminescu, a youngish 130-km (80 mile) wide crater just north of Mercury’s equator. Eminescu made science headlines last year with MESSENGER’s discovery of curious eroded blotches called “hollows” scattered across its interior and surrounding […]
