Dean Regas


He has been the outreach astronomer at the Cincinnati Observatory since 2000, written dozens of articles about the skies above us and co-hosts the popular public television series Star Gazers

Last week, the popular public television series Star Gazers celebrated the airing of its 500th episode, highlighting our continued fascination with the wonders and mysteries of outer space.

The Cincinnati Observatory Center was the first public observatory in the Western Hemisphere, and is known as “The Birthplace of American Astronomy.” Today Greater Cincinnati is home to three observatories.

Dean Regas, outreach astronomer from the Cincinnati Observatory, talks about the 150th anniversary of the publication of Jules Verne’s classic From the Earth to the Moon and some local book club events he’ll be taking part in to celebrate this occasion.

The sun, earth and moon will align for the third time in less than a year next weekend.  In Cincinnati you can see a partial lunar eclipse on Saturday April 4 beginning at 6:15 a.m.

Co-Host of the PBS program, Star Gazers and Outreach Astronomer at the Cincinnati Observatory Dean Regas says:

  If you’'ve had enough of looking at the snow, ice and slush, then bundle-up and head outside and look up at the wonders taking place above us, or attend one of the programs offered by the Cincinnati Observatory.

Early risers are in for a treat Wednesday morning. A total lunar eclipse begins at 5:15 am.  The Cincinnati Observatory's Dean Regas says that's when the shadow of the earth will being moving across the moon creating an orange tint that some refer to as a 'blood moon.'

The moon should be fully eclipsed by 6:30 am and will set around 7:30 am.

  Maybe we just weren'’t paying attention before, but it seems as if there’'s been a lot more celestial activity going on this year. Blood Moons, Super Moons, eclipses, meteor showers, planets in opposition...we’'ve even had a triple Jovian shadow transit. And if you don’'t know what that is, you'’re in luck.

The Cincinnati Observatory, 'The Birthplace of American Astronomy' and home to the oldest professional telescope in the US, is always a wonderful destination for anyone, of any age, who is curious about science, astronomy and the world around them.

This summer, the observatory has several activities lined up to engage, entertain and enlighten those interested in the sun, the moon, Saturn - and other cosmic entities that make up our own solar system.

Pull out a comfy lawn chair, grab some snacks and face to the east this weekend for a view of the annual Perseid  meteor shower.  Cincinnati Observatory Outreach Astronomer Dean Regas said the meteors are about the size of a grain of sand and hit the earth's atmosphere at more than 100,000 miles per hour.  They reach 3,000 degrees fahrenheit, producing the flash of light you see. 

"The only trick is, you have to be up pretty early in the morning to see most of them, usually between 2 and 5 a.m., which is a little early for most folks," said Regas.

The Cincinnati Observatory is celebrating an anniversary this weekend. It was 168 years ago that a prominent Cincinnatian made the city the "Birthplace of American Astronomy."

Ormsby MacKnight Mitchel must have been a pretty convincing guy. In the mid-1800s he went door to door to collect 25 dollar donations for a telescope and observatory. Cincinnati Observatory Outreach Astronomer Dean Regas tells the story.

Dean Regas from the Cincinnati Observatory joins Cincinnati Edition as a monthly contributor, and his Looking Up segment makes a big bang this month as he talks with Bill Prady, co-creator of the monster CBS hit The Big Bang Theory. They discuss the science used in the show, the growth of the characters over the years, and the story behind Raj’s inability to speak to women.
