Just after it whizzed past Pluto, New Horizons took this photo of the dwarf planet backlit by the sun. The image shows mountain ridges and atmospheric haze—lots and lots of layers of atmospheric haze.

Icy mountains (left) contrast with the smooth expanse of Sputnik Planum (right), probably covered in nitrogen ice.

Sunset on Pluto! The sun shines through the “fog” near Pluto’s surface. The shadows come from hills and mountains.

This is the heart-shaped bright spot on Pluto, also known as Sputnik Planum. The white color likely comes from nitrogen ice.

Red arrows show where a glacier flows into Sputnik Planum. Blue arrows point to the edge of the glacier.
