Look low in southwest as the sky darkens in early December. That brilliant “evening star” is actually not a star, but the planet Venus.
Venus is at its brightest now, in part because it’s relatively close by, only about 35 million miles from Earth. Venus is so very bright that it can cast shadows, and it’s sometimes confused with airplane landing lights, or even reported as a UFO.
Early fall nights can be crisp, but it’s rewarding to go out after dark on these clear, moonless evenings to see some stars and constellations in our Western Slope skies.
Rising in the northeast just after dark, you will find a group of stars that looks like a “W” on its side. These stars are part of the constellation Cassiopeia, which commemorates a queen in Greek mythology.
Just about any clear night provides an invitation to go outside and see what’s up. Some nights, however, might offer a special attraction: a meteor shower; a conjunction between the Moon and a bright star or planet; or even a lunar eclipse. If you are a beginner stargazer you can maximize your sky watching efforts by taking a few simple steps.
Start with a star chart, and/or a Planisphere or a star-charting app that runs on a smart phone, tablet, or PC. These are valuable tools in learning the night sky, displaying any number of sky objects for any hour of the night.
