Some really strange things have been photographed on Mars.Exploring Mars has always been of great importance to humans. Not only because Mars is relatively close to Earth, but because the red planet is eerily similar to our own planet in many ways.

The first lander with a rover touched down on Mars was the Mars Pathfinder, a U.S. spacecraft that landed a base station with a roving probe on Mars on July 4, 1997.

Consisting of a lander and a small 10.6 kilograms (23 lb) wheeled robotic rover named Sojourner, it became the first rover to operate on the surface of Mars.

But soon after, other rovers and spacecraft would follow, and we would come to realize that Mars was not the dead, barren world we had once imagined it was.

It was a planet eerily similar to Earth.

Eventually, we came to find that Mars had a thick atmosphere. It had massive oceans, lakes, and rivers and most likely met all the necessary conditions to support life as we know it.

And the more we explored Mars, the more we were left astounded.

During our long journey exploring the red planet, we have photographed and studied Mars in the best way we could, given our current technology.

Not long ago, we listened to what Mars sounds like, and we managed to record the first ‘Marsquake.’

But in addition to exploring and analyzing Mars, the spacecraft orbiting it, as well as the rovers on its surface, has taken some pretty impressive and weird images.

Here, we have selected our favorite images.

The best, weird, of MarsAn image snapped by NASA’s Curiosity rover on May 7, 2015, seems to show what appears to be a Pyramid on the surface of Mars.

But more pyramids exist on Mars, according to claims.

This one, for example, is much larger. However, it’s just a hill. And again, we can thank erosion for the shape.

The face on Mars is another stunning image we can’t leave out of the list. The explanation for this image is that lighting conditions and the camera angle caused the orbiter to photograph a natural formation resembling a face.

Another strange image captured on Mars is the crab-like creature some users claim to see in the next image.

The image made headlines around the world when UFO hunters reported seeing a crab on Mars. Do you think anything could survive on the surface of Mars today? Here’s the image, and judge for yourself.

Here’s the original image of the above image.

Then there’s a massive sphere in the middle of Mars.

As we’ve written in previous articles, the massive sphere is seen in a photograph filed under “M1501228a” and taken in 1999 by the Mars Global Surveyor’s mission.

Not a cannonball on Mars.

Although some internet users were quick to jump to conclusions where NASA posted this image from Mars, the truth is that it’s not evidence of aliens, and it is not a cannonball on Mars.
