Crescent Moon and Venus
|
Caption NASA, da "NASA - Picture of the Day" del giorno 6 Marzo 2009:"Last Friday (such as February, 27th, 2009), the Moon and Venus shared the early evening sky in a beautiful Conjunction.
Separated by only about 2°, they also were both in a crescent phase.
Just like our Moon, Venus can appear as a full disk or a thin crescent. Frequently the brightest object in the post-sunset or pre-sunrise sky, Venus is so small that it usually requires binoculars or a small telescope to clearly see its phase.
This telescopic image of Friday's Conjunction shows off the similar crescent phases, with the tiny crescent Venus at the upper right".
