The Eclipse, Seven Russians, and the 4565 mile Road Trip!
The "Great" solar eclipse last August, bisecting the United States, is a once-in-a-lifetime event for amateur astronomers and not to be missed! However, sometime life interferes and while I SHOULD have been making reservations and itineraries, I was assisting my wife to her chemo sessions, and eventually, planning her memorial service. I found myself 2 months before the event with 7 Russians joining me from halfway around the world, depending on me to have plans, as I started from scratch. But sometimes Dr. Murphy smiles and somehow it all came together. I'm telling the story of how 24 (!) of us ended up on the lawn of a woman and her 2 granddaughters in Shoshoni, Wyoming, by her admission "changing their lives" and ours as well.
Dean Ketelsen grew to love the sky growing up on an Iowa farm. A voracious reader and encouraged by his attendance in a 1-room schoolhouse in grade school, he went on for an undergraduate degree in astronomy at the University of Iowa. After a stint as a grant-funded astronomer measuring radial velocities at Iowa State University, then a technician at Kitt Peak National Observatory, he has worked in astronomical optics at the University of Arizona since 1984, now retired part-time to the Fox River Valley near St Charles.
The development of large scale structure from the cosmic web to galaxies.
What is the universe’s baby picture? Is space really empty? Where do galaxies come from? What is the largest object in the universe? Does the universe look more like meatballs in a soup, Swiss cheese, or a sponge? Most importantly, how do we know? Together we will journey through evolution of the universe from the big bang to present day, unraveling the questions that keep me up at night.
Alex is a 2nd year PhD student at Northwestern university using computer simulations to learn how galaxies form and evolve. When he’s not staring at a terminal he spends his time organizing for the Chicago chapter of Astronomy on Tap and volunteering in the space visualization lab at the Adler Planetarium
