Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

The Chinese-led research team based its findings on seismic readings from NASA's InSight lander on Mars, which recorded more than 1,300 marsquakes before shutting down in 2022. The spacecraft landed ...

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion ...

Scientists peering into the very heart of hearts of the planet Mars have found a deeply unexpected structure. There, at the innermost core of the planet, InSight seismic data reveals a solid mass ...
