Recent gravity studies of Mars have uncovered large, dense structures hidden beneath the planet's surface, offering new insights into the geological activity that may still be occurring on the Red ...

Gravity on Mars. Like all bodies in the universe, the Earth has a gravitational pull. But this pull isn’t constant across our planet’s surface.

Gravity map of Mars. The red circles show prominent volcanoes on Mars and the black circles show impact crates with a diameter larger than a few 100 km.

New images reveal that the strange Martian stripes on the slopes are formed by avalanches of dry dust, not liquid water.

"There seems to be no trace of them at the surface," he added. "However, through gravity data, we have a tantalizing glimpse into the older history of the northern hemisphere of Mars." Thar Side ...
