Finding the Planets

Today, we take a more observational approach to our astronomy lesson which will require you to go outside tonight and look at the stars. If  you've taken a look at the sky lately, you might have noticed a few extra bright objects up there. These bright objects are not really large stars, they are actually the planets in our solar system! Three of the planets (Venus, Mars and Jupiter) are visible just after sunset right now (assuming skies are clear where you are!) To find the planets, start by looking west. You should see two very bright objects in a straight line fairly low in the sky, brighter than any other stars around them. These are Venus (brightest one) and Jupiter! Once you've found them, turn around and look east. There should be another bright object in the sky that has a distinct red hue to it. That is Mars! Below are some images from Sky & Telescope magazine showing you where the planets are in relation to other stars and the moon. (Even though they say April 2nd they are about right for any day this week)

If you happen to have a telescope, or an observatory near by, take a look at these planets. If the night is very clear, you might be able to see the four Galilean moons of Jupiter or even the polar ice caps on Mars! It's really a spectacular sight!
