| How much moon do we see? | | One side of the moon always faces Earth. Even so, over time, lunar libration lets careful observers peek at a tiny portion of the moon's far side. | | | Cottonwood trees and the snows of June | | Cottonwood trees in the American West are a nuisance to some and a treasure to others. They yield shade, beautiful foliage and, in June, a kind of warm, fluffy snow. | | | Amazing views of nearby waltzing stars | | Astronomers used the Hubble Space Telescope to follow the 2 brown dwarfs in the Luhman 16AB system, as they move both across the sky and around each other. | | | | | | |
