Latest NASA Data Show Something Weird is Happening Inside 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?
