Pictures of Pluto

[Science ★]


(P1) Pluto is a dwarf planet at the end of the solar system, and an astronomer discovered it in 1930.

(P2) However, Pluto remained a mystery for decades because it is 7.2 billion kilometers from the earth. That was, until last week when a NASA probe flew by the planet. It took great images. You can see even structures smaller than a mile across.

(P3) The following video shows an animation of Pluto’s images throughout history. You can see a great difference between the first and the last pictures.
