Watch: 'Sad Pluto' short will break your heart
An animated GIF of a cartoon Pluto has gone viral online.
Pluto has been trending on Twitter for almost two days after the first zoomed-in image of the 'dwarf planet' was released.
NASA had successfully completed a 'fly-by' and captured images of Pluto, which went viral as soon as they were posted online.
One cartoonist took a different approach and animated a short GIF of what he thought happened during the flyby.
In the clip, a cartoon Pluto can be seen to spot the oncoming spacecraft and get very excited. However, as the spacecraft passes on by, Pluto realises it's not stopping to say hello and tears well in his 'eyes'.
The GIF has gone viral all over the world as social media users sympathise with the fictional character.
Twitter users have also taken to the platform with trademark quick wit over the breakthrough, and we've gathered some of the best responses below.
The probe travelled more than 3.6 billion miles to snap the photo of Pluto and made it to 7,700 miles above it's surface.
Alan Stern, principal investigator for NASA's New Horizons spacecraft, told media he was "completely surprised" by the findings, which appear to include 'ice mountains'.
The discovery of ice means the discovery of water, which is the first indication that life may be possible on the foreign planet.
