A stunning new infrared image from NASA’s Mars Reconnaissance Orbiter has revealed the worm-like fissures blanketing the floor of a mysterious crater on Mars.

Axar.az reports citing Mail Online.

The image shows the spread of features known as ‘ejecta,’ or the material thrown across the surface after an impact.

In this view, the breathtaking colours indicate the presence of different rocks and minerals, including iron-rich minerals such as olivine and pyroxene.

While the blue features represent iron-rich areas, lighter colours such as yellow show where the rock has been altered, NASA explains.

The image was captured using MRO’s HiRISE instrument.

The experts say the features seen in this unnamed crater in Mars’ Mare Serpentis region are similar to those seen elsewhere, and can help to shed light on the subsurface materials kicked up after an impact.

It’s thought that the ejecta seen here comes from two unnamed craters.

‘These linear features indicate the flow direction of the ejecta from its unnamed host crater,’ according to NASA.
