Scientists have discovered on Mars the source of life

To find out what it is and how it formed, the researchers on the new study measured the density of the Medusae Fossae using gravity data from several Mars orbiters.

"The Medusae Fossae was deposited during explosive volcanic eruptions more than 3 billion years ago", the study authors said.

For decades, the Medusae Fossae Formation, a massive and odd hilly landscape that extends for more than 3,100 miles across Mars's equators has baffled scientists.

The Medusae Fossae Formation (MFF) was first observed in the 1960s via the Mariner spacecraft, but NASA scientists could not explain what caused it. However, according to a new study performed by a group of researchers, the MFF that extends up to three thousand one hundred miles across the planet's equator, was formed some millions of years ago due to a volcanic event on the Martian surface. As per the study, the MFF comprises of sedimentary deposits, which are nearly hundred times larger in comparison to the biggest volcanic deposit witnessed on the Earth.

"This is a massive deposit, not only on a Martian scale, but also in terms of the solar system, because we do not know of any other deposit that is like this", said Lujendra Ojha, a planetary scientist at Johns Hopkins University in Baltimore and lead author of the new study published in the Journal of Geophysical Research: Planets, a journal of the American Geophysical Union.

Also, it is believed that there must be the history of Mars behind the formation of the Medusae Fossae. The combination of hot atmosphere and toxic water would have likely affected the potential for Mars's habitability, explained Ojha said.

Every so often, UFO fans get their knickers in a twist about a "crashed spaceship" on the surface of Mars - as images surface of a odd rock formation near the equator. They found the rock is unusually porous: it's about two-thirds as dense as the rest of the Martian crust. Radar and gravity data ruled out the large-scale presence of ice.

Because the rock is so porous, it had to have been deposited by explosive volcanic eruptions, according to the researchers. Much of the original rock has eroded away, leaving hills and valleys in its wake that are visible today.

The new study suggests Mars' interior is more complicated than previously thought, once harbouring huge amounts of volatile gases to build up a formation the size of Medusae Fossae.

Scientists have found on Mars water source.

If you distribute Medusae Fossae over the entire globe 9.7-meter thick surface layer, concluded Ojha. "Given the sheer magnitude of this deposit, it really is incredible because it implies that the magma was not only rich in volatiles [but] also that it had to be volatile-rich for long periods of time". Carbon dioxide and water from the deep crust of Mars helps in the eruption of the volcanic matter says Kevin Lewis, again a planetary scientist from the University of John Hopkins.
