Venus, bright in the southwestern sky, early in the evening.
Here are a couple of pictures from my iPad of Venus, last night, a bit after sunset.
This one has a plane in it, to the right, which just happened to be flying by a minute or so later than the first picture. That gives an idea of how bright Venus can get in the evening sky.
The brightness of Venus is of course a combination of:
nearness to the sun
nearness to us
high albedo (reflectivity) due to constant cloud cover.
The iPad always surprises me, how well it captures scenes like this. Here's a closeup. There is very little blurring of the planet due to movement of the Earth.
