He is the author of the books “Facts from Space” and “100 things to See in the Night Sky,” and is a contributing editor to Sky and Telescope Magazine and Astronomy Magazine. In 2008, he won the “Out-of-this-World” Award for astronomy education. Regas has written over 150 astronomy articles for the Cincinnati Enquirer, has blogged for the Huffington Post, and is regularly featured on television and radio. He is also a frequent guest on National Public Radio’s Science Friday and NPR’s Here & Now, and hosts his own astronomy podcast with Anna Hehman called Looking Up!

As Grand Canyon's second Astronomer in Residence, Dean spent his time providing public programs on a myriad of astronomy subjects, from the 1969 Moon landing, to constellation tours, to tours of the universe using the latest software. He provided multiple Facebook live sessions for Grand Canyon's online following and conducted several solar viewing and telescope viewing sessions along the South Rim.
