Planets on the Wing
Explanation: Lately, bright Jupiter and fainter Mars have been easy to spot for early morning skygazers. Before dawn
on January 7 the two naked-eye planets will reach a close conjunction near the horizon, only 1/4 degree apart in predawn eastern skies. That apparent separation corresponds to about half the
angular diameter of a Full Moon. Just off the wing of a high-flying aircraft in this snapshot from early morning January 5, Jupiter (left) and Mars (middle) are also lined-up with the well-balanced
Zubenelgenubi (right), alpha star of the constellation Libra. Below are lights from central Europe near Prague, Czech Republic, planet Earth.
