Icy-dwarf Planet

Scientists have unveiled the origin of the large heart-shaped nitrogen glacier on Pluto spotted by NASA's New Horizons spacecraft during its historic flyby of the icy-dwarf planet last year.

NASA's New Horizons spacecraft has sent back some of the sharpest images of Pluto, showing a wide variety of cratered, mountainous and glacial terrains, which may be the best close-ups of the icy-dwarf planet that humans could see for decades.
