Mars Got Cooked by a Recent Solar Storm
The sun fired off a volley of radiation-riddled outbursts in May. When they slammed into Earth's magnetic bubble, the world was treated to iridescent displays of the northern and southern lights. But our planet wasn't the only one in the solar firing line. From a report: A few days after Earth's lig...
When they slammed into Earth's magnetic bubble, the world was treated to iridescent displays of the northern and southern lights. Based on scientific knowledge of atmospheric chemistry, she and other scientists say, observers on Mars would have seen a jade-green light show, although no color cameras picked it up on the surface. Mars's thin atmosphere and the absence of a global magnetic shield meant that its surface, as registered by NASA's Curiosity rover, was showered by a radiation dose equivalent to 30 chest X-rays -- not a lethal dose, but certainly not pleasant to the human constitution.
