NASA’s Latest Image With Mars’ Dunes: The “Ghost Dunes” May Hold Evidence Of Ancient Alien Life

An amazing image showing sand dunes on Mars has been released this week by NASA, reports Fox News.

In the picture, it can be seen that the dunes boast an elongated crescent shape and this is the reason for which these dunes are called “barchan dunes.”

Around them, the landscape of Mars can be seen in blue and brown hues.

According to NASA, these dunes have been formed by the winds that are on the Red Planet which are moving the sand grains up the long slope towards the top of the dunes.

From these movements, ripples result, and according to NASA, the slow sand movement is the cause of these dunes moving gradually over time.

The ghost dunes might hold alien life 

Back in July 2018, there’s been a newly published research that showed some so-called “ghost dunes” on the Red Planet that could potentially still hold evidence of alien life.

The research, published in the Journal of Geophysical Research: Planets, shows that each of the ancient dunes (most likely dunes) are the size of the U.S. Capitol.

“We know that dunes on Earth can support life, and dunes on Earth are very similar to dunes on Mars. One problem that Mars has that Earth doesn’t is the surface radiation,” said Mackenzie Day who is a planetary geomorphologist at the University of Washington and lead author of the study in a statement to the American Geophysical Union.

Day continued and explained that “If you are inside a dune, or at the bottom of a dune, and you are microbial life, the dune is protecting you from a lot of that radiation.”

It seems that these pits might contain ancient dune sandstones around the pits’ edges and this could be a pretty good place to start looking for evidence that could suggest ancient alien life.
