” At this time, Mars was bombarded with asteroids filled with ice. It took place in the first 100 million years of the worlds development. Another intriguing angle is that the asteroids likewise carried organic particles that are biologically important for life,” states Professor Martin Bizzarro from the Centre for Star and Planet Formation.
In addition to water, the icy asteroids likewise brought biologically appropriate molecules such as amino acids to the Red Planet. Amino acids are utilized when DNA and RNA form bases that consist of everything a cell requirements.
The research study was published in the renowned journal Science Advances.
Mars might have had the conditions for life before Earth
The brand-new research study shows that the oceans that covered the whole world in water were at least 300 meters deep. They might have been up to one kilometer deep. In comparison, there is in fact really little water in the world, explains Martin Bizzarro.
” This took place within Marss very first 100 million years. After this duration, something devastating occurred for potential life on Earth. It is thought that there was a gigantic collision between the Earth and another Mars-sized world. It was an energetic accident that formed the Earth-Moon system and, at the same time, erased all prospective life on Earth,” says Martin Bizzarro.
Therefore, the scientists have actually strong evidence that conditions allowing the introduction of life were present on Mars long before Earth.
Billion-year-old meteorite
It was by means of a meteorite that is billions of years old that the researchers have actually been able to check out Marss previous history. The meteorite was once part of Marss original crust and uses a distinct insight into what took place at the time when the planetary system was formed.
The entire secret is hiding in the method Marss surface has been produced– and of which the meteorite was once a part– because it is a surface that does stagnate. On Earth it is the opposite. The tectonic plates remain in perpetual movement and recycled in the planets interior.
” Plate tectonics on Earth removed all proof of what occurred in the very first 500 million years of our planets history. The plates constantly move and are recycled back and damaged into the interior of our world. On the other hand, Mars does not have plate tectonics such that the worlds surface maintains a record of the earliest history of the world,” describes Martin Bizzarro.

A new research study has found that Mars was covered by 300-meter-deep oceans.
Mars is known for its reddish shade, however it is believed that the planet was when blue and covered in water. The truth that Mars may have had water in the previous brings us closer to understanding whether the planet could have supported life.
There is a general consensus amongst researchers that there was water on Mars at some time in the worlds history, but the degree and duration of that water is still a subject of debate.
According to a recent research study from the University of Copenhagen, it is believed that Mars was once covered in a 300-meter-deep ocean of water around 4.5 billion years earlier.

In addition to water, the icy asteroids also brought biologically pertinent particles such as amino acids to the Red Planet.” At this time, Mars was bombarded with asteroids filled with ice.” This took place within Marss first 100 million years. The whole secret is concealing in the way Marss surface area has been created– and of which the meteorite was as soon as a part– because it is a surface that does not move. In contrast, Mars does not have plate tectonics such that the planets surface area protects a record of the earliest history of the planet,” describes Martin Bizzarro.
