A study in the Journal of Climate has drawn a correlation between historical temperature data, movements of the Earth's core, and the length of an Earth day. It's long been known that fluctuations in ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...
