This fist-sized rock on the surface of Mars is part of a deposit of native sulfur, which has been preserved for three billion years. It is interpreted to have been formed by the eruption and solidification of a subsurface sulfur-rich vapor. Learn more this week in Science: https://scim.ag/4ginhe9
We discovered a new rock type containing garnet inside a meteorite fragment from Mars
