Explanation:
That's not a young crescent Moon
poised above the hills along the western horizon at sunset.
It's Venus in a crescent phase.
About 54 million kilometers away and less than 20 percent illuminated,
it was captured by telescope and camera on September 30 near Bacau, Romania.
The bright celestial beacon is now languishing in the evening
twilight, its days as the Evening Star in 2018 coming to a close.
But it also grows larger in apparent size and becomes an
ever thinner crescent in
telescopic views.
Heading toward an
inferior
conjunction (non-judgmental), the inner planet will be
positioned between Earth and Sun on October 26 and lost from view
in the solar glare.
At month's end a crescent Venus will reappear in the east though,
rising just before the Sun as the brilliant
Morning Star.
