2. One image shows what looks like a giant tadpole on Mars.
Human life hasn’t been discovered on Mars, but has there been evidence of animals on the Red Planet? In early 2018, the hard-working Mars Reconnaissance Orbiter captured images of what looks like a massive tadpole with a tail. A researcher determined that it was, in fact, an impact crater. Furthermore, the “tail” was caused by water used to travel in and out of the crater.
Although Mars is now dry, evidence shows that there used to be water on the Red Planet’s surface. This tadpole crater further supports this theory. The tail of the tadpole was carved by water flowing out from the hole and going downhill. Scientists determined that the water was traveling out from the crater based on the surrounding terrain’s height.
