MARS was once covered by a deep sea that could have harbored life, researchers believe.
The Red Planet had enough water 4.5 billion years ago to be completely covered by an ocean between 300 meters and 1 km deep.
dr Martin Bizzarro of the University of Copenhagen said: “Mars was bombarded with asteroids filled with ice for the first 100 million years, which brought the water.”
“Another interesting aspect is that the asteroids also carried organic molecules that are biologically important for life.”
“It is believed that there was a gigantic collision between Earth and another Mars-sized planet. It was an energetic collision that shaped the Earth-Moon system while simultaneously wiping out all potential life on Earth.”
They also brought with them molecules like amino acids, which are the building blocks of life.
Solar winds gradually brushed the water away.
The team of dr. Bizzarro published findings in the journal Science Advances after examining a meteorite that was once part of the original Martian crust.
