Trace aliens who have ever visited Mars?

The hypothetical alien that once visited Mars was given after strange structures were found on the Red planet.

Discovered in the 1960s, Mars 's Medusae Fossae terrain poses a big question for scientists about its formation.

This area consists of rippled hills, sharp mountain tops, polygonal peak structures . stretching over an area of ​​about 2 million km ² . It is described by NASA as the mysterious structure of sediment erosion.

Due to no scientific explanation, in 2016, conspiracy theorists claimed that an unidentified flying object (UFO) from another civilization crashed into the surface of the Red planet and created Medusae Fossae. .

Analysis of images from NASA, YouTube UFOvni2012 channel stated: "If you look closely at the collision location, we can see the shape of a 190m wide UFO, approaching the Martian surface at a low angle and eating into the ground. ".

"The landing is long and the head turns to show that the landing board is gentle" - Scott Waring, who specializes in hunting UFOs, said.

However, in the study published in the journal JGR, USA, scientists believe that the process of forming Medusae Fossae probably marks a key milestone in the history of Mars and climate change of the whole. planet.

Accordingly, this strange structure may be the largest volcanic sediment in the Solar System. Some rocks are the remainder of the massive volcanic eruptions that change Mars's climate three billion years ago.

The author of Guide to UFO investigation Nigel Watson also confirmed these traces probably due to the more natural geological tectonic process.

"This is the largest sediment not only in Mars but also in the scale of the Solar System because we have not yet found such a large size sediment" - Lujendra Ojha, a scientist studying planets at Johns Hopkins University, head of the research team, said.

"The volcanic explosion must be of great caliber to expel all of Mars's oceans to over 9cm. At the same time, greenhouse gases rise during the eruption to warm the Martian surface enough for water. keep the liquid state ".

However, toxic gases such as H ₂ S and SO ₂ also enter the atmosphere. The team also used data from spacecraft flying around Mars to measure material density in Medusae Fossae and found that the rocks were unusually porous, only two-thirds of the density of other regions of Mars.
