A clue to ancient life? What scientists found inside Mars’ frozen vortex
SMRTR summary
Scientists studying Mars' polar vortex discovered that extreme cold and darkness during winter cause water vapor to freeze completely, allowing ozone levels to build dramatically in the atmosphere. This ozone buildup suggests Mars may have once had a protective ozone layer similar to Earth's, which could have shielded the planet from harmful radiation and made it more hospitable to ancient life billions of years ago.
