The InSight lander has detected the first ever ‘Marsquakes’... and revealed something strange going on in Mars’ interior. Deep beneath the crust, inside the molten mantle, InSight detected giant, chunky solid objects. What are they? And what can they tell us about how Mars and Earth formed?

Alex Mccoan explores how data from the Insight lander's seismometer has provided a unique, x-ray-like look at the Martian interior. By studying seismic waves, researchers are uncovering how the planet's internal structure differs from Earth and what these findings reveal about the formation and evolution of rocky planets throughout our solar system.
