Dean Regas:

Your Astronomer

Recently featured in the New York Times

Dean has been the Astronomer for the Cincinnati Observatory since 2000. He is a renowned educator, a national popularizer of astronomy and an expert in observational astronomy.

Dean is the co-host of Star Gazers, a new twist on an iconic backyard astronomy program made famous by Jack Horkheimer, which airs on over 100 PBS stations around the world. He is a Contributing Editor to Sky and Telescope Magazine and a contributor to Astronomy Magazine, where he won 2008 “Out-of-this-World” Award for astronomy education.  Dean has written over 120 astronomy articles for the Cincinnati Enquirer, blogs for the Huffington Post and is regularly featured on television and radio.  Since 2012 Dean has been a frequent guest on National Public Radio’s Science Friday with Ira Flatow, and his first book, "Facts From Space!" hit the shelves in October 2016. His second book, "100 Things to See in the Night Sky" comes out this November. This year he began an astronomy podcast with Anna Hehman called "Looking Up!"  

At the Cincinnati Observatory, he has developed his skills as a dynamic writer and public speaker who brings the complicated field of astronomy down to Earth for students of all ages.

Facts From Space!

From Super-Secret Spacecraft to Volcanoes in Outer Space, Extraterrestrial Facts to Blow Your Mind!

Dean's first book will take you from the Earth to the edge of the universe and back.  Facts From Space is here!

What facts lie ahead?  How did turtles, flies, meal worms, and bacteria become the first living things to go the far side of the Moon?  How do you go to the bathroom in zero-gravity?  Where should we look for aliens? 

You will see a Martian sunset, swirl in Jupiter’s Great Red Spot, and skim the corona of the Sun.  You may not bodily go where no one has gone before, but your imaginations will soar among the stars, see constellations from different perspectives, and fall into a black hole.
