Jeff Moore Biography

Close-up images reveal youthful water-ice mountains rising about 3.5 kilometres above Pluto's surface.

Images reveal a vast craterless plain in Pluto's heart-shaped region, indicating surprisingly young terrain.

The newly revealed icy plain in Pluto's heart is informally named Sputnik Planum, later standardized as Sputnik Planitia.

High-resolution New Horizons images reveal rugged mountains, faulted blocks and detailed textures along the edge of Sputnik Planitia.

Enhanced-color imagery reveals the unusual ridged and scaly terrain of Tartarus Dorsa, nicknamed Pluto's snakeskin terrain.

Topographic analysis identifies Wright Mons and Piccard Mons as possible large cryovolcanoes formed by icy volcanic activity.

Highest-resolution images show erosion and faulting sculpting rugged badlands and a major canyon system in Pluto's northern terrain.

Close-up imagery reveals aligned pits in Pluto's nitrogen-rich ice, probably formed through fracturing and volatile-ice loss.

Analysis of New Horizons imagery confirms dune fields near Sputnik Planitia, showing that Pluto's thin atmosphere can mobilize surface particles.

Pluto's dunes are interpreted as deposits of sand-sized methane-ice grains shaped by winds near the margins of Sputnik Planitia.
