Planet of the Month - Venus

This month, Venus puts on a show on the opposite side of the sky as Jupiter and Saturn. It is the extremely bright "star" in the southwest around sunset. Venus is the brightest object in our sky besides the Sun and the Moon and when it is visible, it shines bright enough to encourage people around the world to call local law enforcement, asking about the strange bright object hovering low in the sky.

Venus reaches greatest elongation east on January 17th, 2001, that means it is as high in the sky as it gets. It shines in the south west, so get out there and have a look. It's dazzling.

In a telescope, Venus looks smooth and plain. That's because the planet is covered with a very thick atmosphere that reflects the Sun's light. Because Venus is closer to the Sun than we are, we can see phases in the telescope much like the Moon's phases.

Even though Venus and the Earth are almost exactly the same size, Venus is a much more hostile planet. In fact, it is so hot, it could melt lead. The reason it is hot is because the carbon dioxide in the atmosphere keeps the Sun's heat in and the result is runaway greenhouse effect. By studying Venus' atmosphere, scientists are better able understand our own atmosphere here on Earth.
