Scientists have finally measured the size of Mars’ core. Shit is less dense than thought!

scientists measure the size of mars core

We finally know the size of Mars’ core, motherfuckers! This is thanks to Astronomy-Wizards and through the measuring of seismic activity, both of which are pretty impressive. What have we found, now that we’ve measured the core? It’s less dense than we thought! Yeah, I said we! As a human, I want in on this shit. Sitting here. In joggers. Farting. Staring at butts. This is it! This is my moment.

Exclusive Club

Mars just joined a pretty exclusive club, thanks to new NASA research.

Following the Earth, Mars is just the second planet in the universe to have its core measured and analyzed by human scientists, Nature News reports. Thanks to the InSight lander’s ability to listen to Mars’ seismic activity, NASA discovered that Mars’ core is less dense than they thought — and just half the size of Earth’s.

Listening In

Scientists can infer certain things about the hidden inner layers of planets from a distance, but getting actual measurements requires landing specialized equipment on the surface. That’s why we have a specific figure for the width of Mars’ core — between 3,620 and 3,720 kilometers in diameter — but only have estimates for other planets, like Mercury and Venus, nevermind exoplanets in other systems.

In this case, the InSight lander was able to listen in on marsquakesNature reports, some of which were strong enough to send seismic waves down to and through the planet’s innermost layer.

“This is going to cause us to reduce our instrument usage over the next few months,” InSight project scientist Mark Panning told Nature.

But until then, NASA still has plenty of data to pore over, like the unexpected finding that Mars’ core is considerably larger and less dense than scientists had estimated. That leaves the InSight scientists with the new challenge of figuring out which lighter elements are in there spacing things out.
