Earlier this week, people were curious about a image of a lizard on Mars that surfaced on the internet. The Mars Lizard went viral in hours. Now, a new image from NASA/JPL has popped up on the internet. This time the picture, taken in 2012 from the Curiosity Rover, has spotted another creature on the surface of the Red Planet. This time, it's a image of a rat on Mars.

If you look closely at the image above, you can see what appears to be a rat, in-between two rocks. The rodent has now gone viral and is being called the 'Mars Rat'. Some speculate that it's a hoax, while others believe that NASA sent animals on board the rovers to see if they can sustain life on the planet's surface.

What do you think? Rat or hoax? You be the judge!
