There is an outstanding rock formation in the alien landscape of Mars.

Experts say the columns were created from cement-like substances that used to fill cracks in the bedrock. The streams of compact material were still standing even as the softer rock began to erode.

There are rock formations on the red planet.

The SETI institute and NASA shared a picture of the rock formations last week as part of a planetary picture of the day initiative.

#PPOD: Here is another cool rock at Gale crater on Mars! The spikes are most likely the cemented fillings of ancient fractures in a sedimentary rock. The rest of the rock was made of softer material and was eroded away. 📷: @NASA @NASAJPL @Caltech #MSSS fredk, acquired on May 17. pic.twitter.com/RGfjmRBfI7

As alien as the structures may look, they are not alone.

A hoodoo is a tall and thin spire of rock. It can also be referred to as a tent rock.

Hoodoos are usually found in dry environments, like the canyons of Utah or southern Serbia, and the columns can sometimes tower as high as ten story buildings.

Hard rock layers form the natural structures. As the rest of the rock erodes away from rain, wind, and frost, you're left with a huge hole in the bedrock.

The two towers of rock on Mars look like they are about to topple over compared to the ones we see on Earth, but they are solid enough to hold up.

It is possible that another strange rock formation was created in the same way.

The smaller rock looks like a flower with small petals stretching up towards the sun.

According to a press release from NASA, one theory is that the rock is a type of concretion created by minerals deposited by water in cracks or divisions.

The concretions can be harder and denser than surrounding rock, and can remain even after the surrounding rock erodes away.

The alien spires found in the Gale crater stand out from the rest of their environment, despite the fact that no height measurement accompanies the image.

The formation of the tombstones of rock speaks volumes about the ancient conditions on Mars.

The crater is thought to be a dried-up lake bed, rather than being shallow and more fleeting than previously thought.

The region's history is being revealed by rock formations around the lake.
