Ancient solar storms may explain how Mars morphed into a cold, barren desert
In March of this year, the sun hurled a giant magnetic solar storm into Mars. The solar wind, full of charged particles, slammed into the red planet’s atmosphere, bouncing or “sputtering” the oxygen into deep space.
Researchers now think the same process could have evaporated Mar’s water several billion years ago, according to a new study presented at the 2015 American Geophysical Union Fall Meeting and recently published in AGU’s publication Geophysical Research Letters.
