The planet Venus is near the moon Wednesday evening.  More on when and
where to look -- right after this.

September 26  Venus and the Moon

One of the most hostile worlds in our solar system is right next door
-- Venus.  Venus has 900-degree-Fahrenheit surface temperatures -- and
such tremendous surface pressure that standing on Venus would be like
being underwater on Earth, some half a mile beneath the surface of an
ocean.  Venus also has fearsome lightning -- acid rainfall -- and an
unbreathable carbon dioxide atmosphere.

The planet Venus is completely blanketed by thick yellowish clouds --
so we can't SEE its surface.  But spacecraft and earth-based radar have
probed the surface of Venus.  And in the past year it's begun to look
very likely that active volcanoes sometimes erupt beneath the Venusian
clouds.

So Venus is a violent, hostile world on its surface -- but from our
vantagepoint across the gulf of space, it's one of the most beautiful
worlds in Earth's sky.  Its clouds are good at reflecting sunlight --
so Venus is extremely bright -- brighter than anything else in the sky
besides the sun and moon.  Possibly because it's so bright and fair,
Venus is the planet named for the ancient Roman goddess of love.

This world spent most of 1984 moving on the far side of the sun from
Earth.  But now Venus is back in our sky -- visible low in the west
after sunset.  Wednesday night is a good time to look for Venus because
then the planet is located near the crescent moon -- which has also
just returned from a short visit into the sun's glare -- and which'll
be visible this coming week as a waxing crescent, smiling down from the
western sky.
