Extraterrestrial life might have existed on Mars millions of years ago as evident in the cyclic climate on the red planet.
The peer-reviewed study titled "Sustained wet-dry cycling on early Mars" suggests that it might be linked to the origin of life in the region.
Recent Martian Discoveries
As The Jerusalem Post reports, a team of researchers recently discovered that the Martian landscape might tell how Mars looks like in the past.
According to the experts, Mars might have a similar cyclical climate to Earth as the study's conclusion says.
Judging from its terrain, the Earth's neighboring planet is not accentuated by tectonic plates. This led the researchers to see the clear formation of fossil lakes which are believed to have existed billions of years ago.
Furthermore, the team uses the data from the Curiosity rover which has helped them detect the organic molecules that biologically changed over time.
This could give us clues that primitive life forms once inhabited the iron-riddled planet. Scientists continue to uncover the Martian landscape and its connection to the existence of the earliest organisms.

Hexagonal Patterns Could Tell More About Martian Climate
With the latest discovery of the hexagonal pattern on Mars, the team might have already debunked the climate of Mars from way back.
The unusual shape of the sedimentary layers tells that Mars also has dry and wet seasons. This way, experts conclude that the conditions are ideal to grow life.
"The presence of perennially wet surface environments on early Mars is well documented," the study notes.
According to the team, the chances that primitive life forms existed here are big. Speaking of which, the researchers might be pertaining to the microscopic organisms.
For French National Center for Scientific Research's scientist William Rapin, the dry and wet spells could indicate that DNA could be formed at any time.
It was the first time the team to see a Y-shaped mud crack on the Martian surface. This means that the land has been exposed to erosion and this could explain why a single form of life is not discovered here.
If the Martian terrain is conducive to producing potential signs of life, this could also hint that extraterrestrial beings existed on the red planet at some point in time.
Mar is Spinning Faster Annually
In another report by Tech Times, researchers said that Mars is spinning faster every year. Based on the findings posted on Nature.com, the red planet is rotating for as much as about 4 milliarcseconds yearly.
The data also says that the behavior of the planet is affected by the "sloshing" of the molten metal core. Another finding says that it's because of the accumulation of ice on the post-glacial rebound.
