A new map shows Pluto's surface is covered with water ice

It's more frozen water than scientists initially thought existed on the dwarf planet's surface

(CNN) —  

Talk about an endless winter: Pluto has way more frozen water than scientists originally thought.

The dwarf planet is coated with a large amount of ice, according to a new map using previously collected data from NASA’s New Horizons spacecraft.

This map is more sensitive than an earlier version that was created using data by New Horizons’ historic fly by in 2015. The previous map was at a disadvantage because water ice can be easily masked by frozen methane. So it only showed areas with an especially large amount of frozen water.
