Astronomers have discovered what lies at the core of Mars
In an incredible first, astronomers have discovered what lies at the core of Mars. It turns out, the Red Planet isn’t as lifeless as we once thought. Mars wasn’t always a dusty, barren world. There’s plenty of evidence that the planet was warm, had lakes of liquid water, and was habitable for a short period in its history. Astronomers had always wanted to know the reason behind this transition, and for that, they had to know what lies at the core of Mars. When the InSight lander started studying the planet’s interior, it discovered that the planet is still rumbling with seismic activity. Now, following a rigorous half-decade mission, InSight has granted scientists a clear vision of the Martian core.
So, how does Mars’ core differ from Earth’s? What methods did InSight employ to unveil the core of the Red Planet? Finally, and most importantly, what does it tell us about the future of our planet?
The 61st episode of the Sunday Discovery Series answers these questions.
