Ghost dunes could suggest life of microbes on Mars, say scientists

New Delhi : Mars has been the planet of mystery for scientists for centuries. In an attempt to understand the red planet, scientists now believe that ancient formations on Mars can lead to the life of microbes. The strange "crescent-shaped" ghost-dunes appearing on the surface of the planet could certainly reveal clues to the possibility of an old microbial life

The lowest point marks the place where you'll find yourself. Huge sand dunes reach billions of years. since. Experts continue to update Mars' past climate and wind changes, and now they say that impressions could be helpful in chasing the ancient existence because they could have harbored microbes against cruel radiation.

are impressions left after lava or sediments transported by water buried the sand structures and preserved their contours. The phenomenon has been explained by researchers in the new study published in Journal of Geophysical Research: Planets.

Although the wind may have lifted bare sand from the sand and carved pieces, the solid mold is left behind.

were observed in satellite images of Mars, in the Hellas Basin and Noctis Labyrinthus. The team found more than 480 potential structures at Noctis Labyrinthus, and more than 300 in the east of Planita Hellas.

The average dune was about 130 feet and 246 feet in height.

"No matter which of these pits is not enough for you that it's a dune, or an old dune field, but when you put them all together, they have so many d & # 39; 39 common aspects with the dunes on Mars and Earth that you have to use some kind of fantastic explanation to explain them as something else, "said Mackenzie Day, a planetary geomorphologist from the University of Washington in Seattle "One of the cool things about the ghost dunes is that they tell us, for sure, that the wind on Mars was different in the past, when they formed."
