What Did We Learn About Pluto? Highlights from NASA's New Horizons MIssion

TL;DR

NASA's New Horizons mission reveals surprising discoveries about Pluto, unveiling icy plains, mountains made of ice, and an atmosphere.

Transcript

Clyde Tombaugh first discovered Pluto in 1930 he saw only a single speck of light moving slowly in front of the background stars as he flipped photographic plates back and forth sadly this was the best anyone could do for decades even the mighty Hubble the most sensitive instrument ever focused on Pluto could only resolve a few grainy pixels it's b...
