A new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle (the layer between a planet’s core and crust). For decades, scientists argued that hit-and-run ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an unusual “buttery” state of matter, one that challenges long-standing ...

Physicists suggest a new explanation for the interesting properties of the Earth's inner core. Credit: NASA / Getty Images According to a new "holy grail" scientific discovery, the blazing-hot ball of ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

If the explorers from Journey to the Center of the Earth were to journey to the center of Mars instead, they definitely wouldn’t come across the subterranean oceans or live dinosaurs they encountered ...

Analysis of Martian seismic data recorded by the InSight mission in combination with first-principles simulations of the seismic properties of liquid metal alloys have revealed that Mars’s liquid iron ...

Iron is more dense and hence, when the young Earth was molten, it tended to sink. Lighter elements, such as silicon and aluminium, floated to the surface and, as Earth cooled, the crust contained ...
