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. A gravity high signal is located in the ...

Mars' magnetic field may have survived 200 million years longer than scientists had thought — crucially, long enough for it to overlap with the presence of liquid water on the surface of the Red ...
