Liquid water once shaped the Martian landscape dramatically, carving valleys, filling lakes, and forming vast oceans.

By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid ...

By listening to the echoes of "marsquakes" — seismic waves rippling through Mars ' crust — researchers uncovered signs of ...

Their findings revealed something surprising: at a depth of 5.4 to 8 kilometers beneath the surface, there is a significant ...

Our new study may offer an answer. Using seismic data from NASA’s InSight mission, we uncovered evidence that the seismic ...
