23. If you are hungry, you might think this is a real jelly donut.

On January 8, 2014, Mars rover Opportunity captured an image of a rock that looked strangely like a jelly doughnut. Pictures taken a few days before in the same spot did not show the same object. Many people considered that aliens or a meteorite collision could have been responsible for the jelly doughnut.

Some concerned citizens believed that the jelly doughnut could be evidence of fungus growing on Mars. Scientists eventually realized that the jelly doughnut was simply a rock. Opportunity’s wheels most likely kicked up the rock. While it looked like a tasty treat was present on Mars, it was just a simple rock formation!
