                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: This is a gibbous Moon. More Earthlings [4] are familiar with a
full moon, when the entire face of Luna [5]  is lit by the Sun [6] , and a
crescent moon [7] , when only a sliver of the Moon's face [8]  is lit. When
more than half of the Moon is illuminated, though, but still short of full
illumination, the phase [9] is called gibbous [10] . Rarely seen in television
and movies, gibbous moon [11] s are quite common in the actual night sky. The
featured image [12]  was taken in Jämtland [13] , Sweden [14] near the end of
last month. That gibbous moon [15]  turned, in a few days, into a crescent
moon, and then a new moon [16] , then back to a crescent, and a few days ago
back to gibbous. And this same gibbous moon [17]  is visible again tonight,
leading up [18]  to the Full Beaver Moon [19]  that occurs Friday night.
Setting up to capture a picturesque gibbous moonscape, the photographer was
quite surprised [20]  to find an airplane, surely [21]  well in the
foreground, appearing to fly past it.
