Heart-shaped region on the dwarf planet’s surface features dunes made out of solid methane
Dunes made out of solid methane particles have been discovered on Pluto.
An international team of researchers reviewed photos of the Tombaugh Regio – dubbed ‘the heart’ – snapped by the New Horizon space probe during its 2015 fly-by of the dwarf planet when they discovered 357 regularly spaced ridges along a bordering mountain range. Although these rippled features look like transverse sand dunes found on Earth, they are actually made of small methane ice particles.
