UFO expert claims to have discovered “tomb” on Mars

Life on Mars could have existed for a long time, new images from NASA suggest.

Scientists who have studied images taken by the space agency’s Mars Reconnaissance Orbiter believe that clayey sediments can be seen within.

The images show a particular area of ​​Mars known as Margaritifer Terra that is ancient and cratered. Nasa previously shared an image of what it believes was once an ancient pond on the planet.

If clay is present on Mars, it would reinforce theories that the Red Planet harbored water at one point.

A study published in the journal Icarus suggests that water may have been found in the Ladon Basin region within Margaritifer Terra from about 3.8 billion years ago to about 2.5 billion years ago.

Catherine Weitza senior scientist at the Planetary Science Institute in Arizona, said: “The presence of loam indicates an environment conducive to life, as loam forms and remains stable under neutral pH conditions where water persists long-term, minimizing evaporation is used to form other minerals such as sulfates.”

Ms. Weitz added: “Colourful, light-toned, stratified sediments showing relatively low stratification and containing clays over a distance of 200 kilometers are evidence that a lake was most likely present in the Ladon Basin and northern Ladon Valles. The low-energy lake location and presence of clay support an environment that would have been conducive to life at the time.”

However, if water was once present on Mars, it does not guarantee that life existed on the planet at any point in time.

Even if a planet had the conditions needed to support life, that doesn’t mean life definitely existed there.
