Marsquakes indicate a solid core for the red planet, just like Earth

CAPE CANAVERAL, Fla. (AP) — Scientists revealed Wednesday that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...

The Earth’s core is slowing down: Why your days might get slightly longer

Earth's inner core, once rotating faster than the surface, has begun to slow, impacting day length by fractions of a second. This subtle shift, detected through seismic wave analysis, reveals complex ...

Marsquakes indicate that the inner core of the red planet is solid, not liquid

An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...

Earth’s inner core is changing speed: Here’s what that means for day length

Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This subtle change, occurring around 2010, may slightly alter the length of our ...

'Marsquakes' indicate a solid core for the red planet, just like Earth

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 ...
