Belt of Venus and Earth's shadow

The Belt of Venus is an atmospheric phenomenon visible shortly before sunrise or after sunset, during civil twilight. It is a pinkish glow that surrounds the observer, extending roughly 10–20° above the horizon. It appears opposite to the afterglow, which it also reflects.

In a way, the Belt of Venus is actually alpenglow visible near the horizon during twilight, above the antisolar point. Like alpenglow, the backscatter of reddened sunlight also creates the Belt of Venus. Though unlike alpenglow, the sunlight scattered by fine particulates that cause the rosy arch of the Belt shines high in the atmosphere and lasts for a while after sunset or before sunrise.

As twilight progresses, the arch is separated from the horizon by the dark band of Earth's shadow, or "twilight wedge". The pinkish glow is due to the Rayleigh scattering of light from the rising or setting Sun, which is then backscattered by particulates.

I think it’s time to update my header image.

Certe sere rimango a guardare le luci della città fuori dalla finestra e mi chiedo dove siano finite tutte le persone che giuravano di non andarsene mai. Poi sorrido, perché capisco che il bello della vita è anche questo continuo cambiare di attori sul palco.
