Kelly Kizer Whitt (Solar System Forecast) has been an admirer of the universe since childhood. From the dark skies of her hometown of Sauk City, Wisconsin, she would gaze at the stars and wonder what was beyond them. Kelly majored in English and studied Astronomy at the University of Wisconsin-Madison. After college she spent three years in Nashville with her husband, Jeremy, before moving to the Milwaukee area. In 1998 she landed her dream job at Astronomy magazine, where she worked as copy editor, photo editor, and assistant editor. Kelly wrote the terrestrial planets section of The Collins Illustrated Encyclopedia of Space, published in 2001. She writes about space for the websites Suite101.com and AstronomyToday.com. She also has a weekly stargazing blog for the Sierra Club online. Besides writing about space, Kelly published a romance novel on Kindle in 2011 titled The Gathering Storm. Kelly’s hobbies include visiting the national parks, creating crossword puzzles, and reading. Kelly lives in Sussex, Wisconsin, with Jeremy, her son Kaden, her daughter Lucy, and their cat Perseus, named for the constellation.
