  Bringing the universe down to Earth…  Dennis L Mammana Astronomer
Join Dennis for a northern lights adventure of a lifetime, as we gaze upon the stunning skies of Interior Alaska. If you've been holding off, keep in mind we’re nearing the top of the 11-year solar activity cycle when the northern lights are at their strongest. Few places on Earth are as good for viewing the lights as Fairbanks, Alaska, the aurora capital of the U.S., and it’s here where you'll learn to predict, view and photograph these most magical of dancing lights. During the daytime we’ll visit the University of Alaska’s remarkable Museum of the North, the Trans-Alaska Pipeline, the World Ice Art Championships and more. And we’ll spend four days/nights enjoying the Chena Hot Springs Resort where we can hike, go dog sledding, visit the Ice Museum or the Geothermal Energy / Greenhouse, or just relax with a dip in the natural hot springs. And, of course, you’ll have each night to seek out the northern lights at your leisure, or with Dennis and/or others in our group. To learn more about this amazing week, please send Dennis an email right away. Only a few more rooms remain available. I know you’ll have a fantastic time you won’t soon forget!

The last total solar eclipse visible from a broad area of North America until 2044 will occur on April 08 of next year. If you've never experienced the indescribable excitement of this rare celestial wonder, I hope you'll join me in Mazatlán for this once-in-a- lifetime experience. For those who have experienced it, you’ll need no extra encouragement! Why Mazatlán? Because the average April cloud cover there is the lowest along the entire path of totality. Plus, it’s a warm and inviting city to visit and explore. Along with Dennis will be lecturers Seth Shostak (SETI Institute) and Rich Talcott (Astronomy Magazine) to share with you presentations that’ll keep you looking up!
