For years, geologists have been searching for an explanation for two strange blobs of Earth's mantle that are denser than the rest. It turns out, they may not be original parts of Earth at all.

When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...

There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on...

Explaining strange Earth geology is often straightforward — combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on this planet are so easy to figure out. From the ground randomly...

We’ve done a surprising amount of exploration on Mars, from its atmosphere, to its surface, and miles deep into its canyons. But mapping its insides has been a quandary that we hadn’t been able to solve until last week!

We finally have some results from the InSight lander’s measurements on Mars, and the Japanese Space Agency is moving forward with a probe that will explore Mars’s moons.

Mars InSight will be the first to detect seismic activity on Mars’ surface, first to measure rate of heat transmitted from interior, first to dig nearly 5m down, first to measure magnetic fields on Mars’ surface, and first to use a...

NASA’s InSight lander touched down in the Elysium Planitia region of Mars in November of 2018. During its time on the Red Planet, InSight has achieved all its primary science goals and continues to hunt for quakes on Mars....

An update for the NASA InSight mission to Mars. What has it seen and discovered so far?

It has been an extraordinary year in Mars exploration, with new results and new spacecraft changing our view of the red planet.





The highlight for many was the touchdown of NASA's...

NASA’s InSight lander completed a seven-month journey through space after landing on Mars yesterday, but its work on the Red Planet has only just begun. The probe has sent initial images of its landing site – the Elysium...
