Astronomy Picture of the Day

                         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: What can you see [3]  in the night sky this season? The featured
graphic gives a few highlights for Earth [4] 's northern hemisphere. Viewed as
a clock face centered at the bottom, early (northern) winter sky events fan
out toward the left, while late winter events are projected toward the right.
Objects relatively close to Earth [5] are illustrated, in general, as nearer
to the cartoon figure with the telescope at the bottom center -- although
almost everything pictured can be seen without a telescope [6] . As happens
during any season, constellations [7]  appear the same year to year, and, as
usual, the Geminids meteor shower [8]  will peak in mid-December. Also as
usual, the International Space Station [9]  (ISS) can be seen, at times [10] ,
as a bright spot drifting across the sky [11]  after sunset. Less usual, the
Moon is expected to pass nearly in front [12]  of several planets in early
January. A treat this winter is Comet 46P/Wirtanen [13] , already bright [14]
, will pass only 36 lunar distances from the Earth in mid-December,
potentially making it easily visible [15]  to the unaided eye.
