Word Of The Day

Lunar libration:

Most of us learned in school that the same side of the Moon always faces Earth. That’s not entirely true. The Moon actually wobbles back and forth, rocking and rolling as it elliptically orbits Earth. These lunar librations allow us to “peek around the edges.” Over time, up to 59% of the lunar surface can be observed from Earth. [Spaceweather.com]
