Old Apollo rocks are providing a fresh take on the moon's magnetic field. The lunar magnetic field is currently weak or even nonexistent, but cranked up to superstrength for short snippets of time more than a billion years ago.

It's the First Quarter tonight.

The Moon doesn't have tectonic plates that move around like Earth's, but it does have its own internal activity. After it formed around 4.5 billion years ago, it was a hot, gooey ball of molten material that has been slowly cooling ever since.

The moon and Pleiades will glow together on Feb. 23 in a striking skywatching display.

Look high in the southern sky tonight (Feb. 24) to see the moon shining close to the stars of the constellation Taurus, mere hours after reaching its first quarter phase. Its right half will be bathed in sunlight and its left hidden beneath a cloak of shadow.
