Explanation:
Taken on February 20,
five different exposures made in rapid succession
were used to created this tantalizing telephoto image.
In combination, they reveal a wide
range
of brightness visible to the eye on that frigid evening, from the
urban glow of the Quebec City skyline to the
triple conjunction of Moon, Venus and Mars.
Shortly after sunset the young Moon shows off its bright crescent
next to brilliant Venus.
Fainter Mars is near the top of the frame.
Though details in the Moon's sunlit crescent are washed out,
features on the dark, shadowed part of the lunar disk are remarkably clear.
Still lacking city lights
the lunar night is illuminated solely
by
earthshine, light reflected from the sunlit side
of planet Earth.
