NASA captured images of this bright blue sand dune on the red planet.

The photo was taken in Lyot Crater, known for its patterned ground.

The dune has a different composition to dunes nearby, hence its colour.

NASA has found an exquisite sand dune on Mars that is literally out of this world, it announced on Wednesday.

The photo of the electric blue sand dune was taken in the region of Lyot Crater, a large crater on Mars that is known for its patterned ground — hence the unusual patterns.

"It is made of finer material and/or has a different composition than the surrounding [dunes]," NASA said.

The space agency's Mars Reconnaissance Orbiter (MRO) captured the image which dates back to January this year.

Mars will be the closest to Earth in the coming weeks than it has been in 15 years, and if you are checking out the Red Planet, remember to keep a look out for a tinge of blue.
