A meteor shower from magnesium, sodium, iron and five other metals may have been so heavy that it might be even considered a meteor storm, said University of Colorado scientist Nick Schneider. Spikes in magnesium physically changed the atmosphere around Mars, while sodium left a yellowish glow in the sky after the meteor showers finished, he said.
"It would have been truly stunning to the human eye," said Schneider, who was the lead instrument scientist for one of NASA's Martian satellites. "It would have been really mind-blowing."
