Astronomically speaking, which is a familiar sign of winter?
-Orion making its way across the evening sky
-Mars shining brightly in the southern sky
-The Galilean meteor shower
-Andromeda galaxy visible in eastern night sky
When winter arrives, early nightfall and crisp morning air greet us. Branches of trees are leaf-bare, and we can see Orion marching his way across the evening sky. These are all the familiar signs of winter’s arrival. Winter tends to be a time for turning inward; a time for introspective quiet, sleeping in and staying home. There’s also another side: the hustle and bustle that signals the “holiday season” that comes with winter’s cold. Source: MotherEarthLiving.com
