Many times, we are at the telescope waiting for the sky to get darker. The Sun had set about a half hour to go, but with light pollution the sky is still not dark enough for targets to come out. Are you in your yard with family waiting to share your hobby with them? Or, are you on the Riverwalk supporting NAA’s outreach to the community? Wherever you may be, the wait for a target makes you nervous as expecting faces, whether friend, family, or visitor to your telescope, are staring at you to show them an out-of-this-world object.
Interested in learning what you can find in the twilight, when the moon or bright planets are not in view? The choice is easy, come to this month’s Fundamentals, where long-time member and outreach veteran Rick Gering will show you how to use a pair of binoculars, an app like Sky Safari, your telescope’s optical finder, and a little advance planning to find “wow” targets while the sky is still in twilight. Our September Fundamentals Program will be held on September 16th at 7:30 pm, at the Naperville Municipal Center, located in downtown Naperville, at Aurora Ave. & Eagle St. The location is downstairs, in Meeting Room B. The public is welcome to attend, free of charge.

The Cosmologist’s Puzzle: The Age and Expansion Rate of the Universe.
We are confused about how old the Universe is. Until recently, astronomers estimated that the Big Bang occurred between 12 and 14 billion years ago. Astronomers can place a lower limit to the age of the universe by studying globular clusters. Globular clusters are a...
