With fewer hours of sunlight during autumn the nights grow longer and there is a distinct chill in the air after the sun sets. You may notice the sky appears darker and the stars just a little clearer. A star chart or an astronomy app for a phone or tablet will guide you to the fall constellations and many of the stars visible in our skies.
On these late October evenings, you may see a hazy band of light stretching from the southwestern horizon and crossing overhead to the northeast. This is the Milky Way, an object of great wonder throughout human existence.
Next time you see the Big Dipper out of the corner of your eye, take a look at the star in the middle of the handle. If you have decent eyesight, you may see not one, but two stars: a brighter star known as Mizar, and a fainter star called Alcor.
"BORING!" said the 5-year-old of the little blue dot appearing through the telescope…
Perhaps at first glance, but considering that Neptune, the 8th planet, is 30 times farther from the Sun than Earth, it’s actually an amazing sight. At approximately 2.8 billion miles away, it cannot be observed with the un-aided eye. Seeing the disk and color requires a moderately sized telescope, and a keen-eyed astronomy buff.
As the holidays approach, the days shorten, bringing with them our glorious Western Slope night skies. Joining us to celebrate the season is a brilliant cluster of stars, called the Pleiades, or Seven Sisters.
Rising on our eastern horizon, the Pleiades first appears as a cloud-like thumbprint. As your eyes adapt to the darkness, you’ll be able to pick out point-like stars, as many as six or seven.
This is the third in a series on Women in Astronomy. Today, we meet Caroline Herschel.
Caroline Herschel was born in Hanover, Germany in 1750. Her early life was a conflict between her father, who wanted her to be educated in music and science, and her mother, who thought that household chores were the appropriate life for a woman.
In 1772, Caroline moved to England and joined her brother, William, who was already working in astronomy and music. Over time, they gradually left music and became full-time astronomers.
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.
