Nasa has finally discovered what caused Mars to become a barren, lifeless world.

Nasa has finally discovered what caused Mars to become a barren, lifeless world.
In a much-anticipated announcement, researchers have revealed that our sun robbed the red planet of its water and atmosphere.
And the process is still happening today, with Mars' upper atmosphere slowly being eroded by solar winds.
The space agency said the discovery could provide new insights into Mars' history, evolution, and, possibly, the planet's habitability.
Maven has discovered that the sun robbed the red planet of its once-thick atmosphere and water.
In March, the probe spacecraft caught a solar storm stripping away the planet's atmosphere
The solar wind stripped away about 100 grams of atmospheric gas every second.
One side effect is that this creates stunning global auroras over the entire planet.
Major solar storms were more prevalent in the solar system's early history.
So billions of years ago, these storms gutted the Martian atmosphere, as opposed to the much lower loss ongoing today.
Ultimately, the research should help scientists pin down a better window of time when Mars was most suitable for Earth-type life to evolve.
