Scientists have long known that the Sun’s surface rotates faster near the equator, where it rotates about once every 25 days, than it does near the poles, where it rotates about once every 33 days.

The moon no longer has a magnetic field, but NASA scientists are publishing new research that shows heat from crystallization of the lunar core may have driven its now-defunct magnetic field some 3 ...

A sample brought back to Earth by the Apollo 15 mission in 1971 indicates that the interior of the Moon may have been active for longer than previously believed. According to researchers at MIT and ...

How low-mass stars produce their ubiquitous magnetic fields has long puzzled astronomers. Models of how Earth accomplishes this task could hold the key to understanding the phenomenon on such stars.

Many astronomers (me included) are somewhat puzzled as to why massive stars only rarely exhibit strong magnetic fields at their surfaces. Part of the reason certainly arises from the fact that massive ...

The sun’s enormous magnetic field is about to flip, and the effects of this massive realignment will be felt throughout the solar system, including here on Earth. But don’t expect anything too crazy ...
