The Northern Lights

One summer, when I was growing up, it was common to hear about sightings of the “northern lights” over Grand Mesa. Most of the stories came from high school kids staying out too late on dates. At the time, I scoffed at those stories, but have since learned that that summer happened to be during a particularly active sun cycle.

Albireo: Double Star

Albireo is a beautiful double star in the constellation Cygnus, the Swan.  If you heard the previous edition of Western Slope Skies, you learned about the Summer Triangle, which includes Deneb, the tail of Cygnus.  Albireo is the head of Cygnus and is dimmer than Deneb. 

Many stars have Arabic names dating back hundreds of years.  For example, Deneb means ‘tail.’  Because of the history involving several languages, the current name Albireo, while appearing to be Arabic, is actually meaningless.

Venus Meets Regulus

As these early fall days grow shorter, our western slope skies are still dark at 6:00 AM.  So, this is a great time to see a celestial spectacle in the morning without having to get up too early.  From September 29 through October 7 the brilliant planet, Venus, often called the morning star, will be moving past Regulus, the brightest star in the constellation Leo.

The Summer Triangle

The Summer Triangle dominates the summer sky. It crosses the hazy band of the Milky Way, which is split into two by a large dust cloud near the star Deneb.

The points of the triangle are three of the brightest stars in the summer sky, and each is the brightest star in its own constellation. The brightest is Vega, in Lyra; second is Altair, in Aquila; and third is Deneb, in Cygnus. Even city-dwellers with glowing, light-polluted skies can find the Summer Triangle.

The Summer Milky Way

On  clear August nights,  the Milky Way extends brilliantly from our southern  horizon, creating a beautiful vision of stars,  reflected light, nebulae, gas and dust.   As darkness falls, and you step outside, it first appears as a band of clouds reaching across the sky. These "clouds" are actually stars that cannot be distinguished from one another with the unaided eye.  In the southern portion you will be able to pick out constellations like Sagittarius, the Archer, more commonly known as “the teapot”, and Scorpius, the scorpion, pinchers reaching upward, tail trailing.

August Meteors

During the wee morning hours from August 9th to the 14th, you may see tens of meteors per hour streaking across our Western Slope Skies. This is the annual Perseid Meteor Shower, one of the most reliable of about 20 meteor showers that occur during the year.  Meteors, sometimes called “shooting stars”, are actually debris from comets or asteroids that have entered earth’s atmosphere at high speed. The Perseid Shower consists of icy and rocky debris from Comet Swift-Tuttle, a 17 mile-wide comet that last passed near Earth in 1992.
