Pic of 'heart-shaped' glacier on Pluto released by NASA
NASA has released a picture captured by its New Horizons spacecraft, showing a heart-shaped glacier on Pluto's surface. It also features mountains, cliffs, valleys, craters and plains, thought to be made of methane and nitrogen ice, NASA stated. "Pluto's surface is marked with cracks and craters in shades of brown," the space agency wrote about the image.
