With the arrival of warmer temperatures, perhaps you’ve been enjoying some outings to the mountains or a float trip on a river. While there is no doubt that summer is in full swing here in western Colorado, it’s not until this coming Saturday that the Universe makes it official.
Those of us that live on the Western Slope are no stranger to spectacular scenery. The jagged peaks, chiseled canyons, and expansive plateaus of western Colorado are treasures that we all cherish. But one of our most spectacular natural wonders may also be one of our least appreciated: our incredibly dark and pristine night skies.
Have you ever seen the planet Mercury? When conditions are near optimal, Mercury is easy to see. However, optimal conditions are rare, and many casual observers search for Mercury without success. This is because of the planet’s proximity to the sun. The safe time to view Mercury is after sunset or before sunrise, depending upon the Mercury's orbit.
Last month on the program we learned that only the five superior planets can be at opposition. The fast movement of our planet’s orbit brings us between those five planets and the sun every year. In April, Mars was at opposition. This month, on Saturday, May 10th, its Saturn’s turn to shine!
The Big Dipper is a great starting point for learning the night sky. Located near the pole of the sky, it never completely sets or dips below the horizon—it’s visible in the night sky year-round from the Western Slope!
The Big Dipper itself is not a constellation, but it resides in one called Ursa Major, the Great Bear, third largest of the 88 constellations. The name originates from the dipper-shaped pattern formed by the seven main stars in the constellation.
Late on the evening of April 14th and into the early morning hours of April 15th, skygazers throughout the America’s and much of the Pacific region will be treated to a total lunar eclipse. This eclipse will be the first of two for the year. By the time the sun, earth and moon line up it will have been 857 days or 28 months since we last saw our moon completely in the shadow of our planet.
