Welcome to Houston Astronomical Society

Fostering the science and art of astronomy through programs that serve our membership and the community. Founded in 1955, Houston Astronomical Society is an active community of enthusiastic amateur and professional astronomers with over 70 years of history in the Houston area. Through education and outreach, our programs promote science literacy and astronomy awareness. We meet via Zoom the first Friday of each month for the General Membership Meeting and the first Thursday of the month for the Novice Meeting. Membership has a variety of benefits, including access to a secure dark site west of Houston, special interest groups that focus on particular areas of astronomy, an active community outreach program, and much more. Joining is simple.

Planetarium applications are widely used by astronomers, educators, and enthusiasts to explore the universe, plan stargazing sessions, and visualize celestial events.  In this month’s Novice Meeting Chris Morisette will present a brief overview of the functionality of planetarium apps, then dive into a demonstration of Stellarium where parameters such as time, location, and Bortle rating will be adjusted in order to get a dynamic view of the night sky.

Speaker BioChris Morisette is HAS Novice Chairperson and an active member of the Houston Astronomical Society, North Houston Astronomy Club, and the Fort Bend Astronomy Clubs.  He is also a member of the University of Texas Astronomy Department Board of Visitors.  On clear Saturday nights you may find him volunteering at the George Observatory engaging visitors and sharing his love of the night sky, or you may find him at the HAS dark site trying his hand at astrophotography.

HAS General Meeting - May 2nd 2025 -HAS Dark Site Development

 

“HAS Dark Site Development

1979 to Present”

 

By: Steve Goldberg

One of the best assets an astronomy club can own is their own private, dark sky observing location. The HAS is fortunate enough to have an 18-acre dark sky site away from the Houston light pollution dome. Steve Goldberg will discuss the development of the HAS Dark Site from the mid-1970s through today.

Steve along with other notable HAS members were key players in the site’s development, from the initial land clearing and first working building through its present configuration. The site has grown from humble beginnings to a true astronomy village for HAS members to use and support.

Speaker: Steve Goldberg has long been interested in astronomy since “discovering” Saturn with his own telescope many years ago. He is past president of the Pontchartrain Astronomy Society in New Orleans and the Houston Astronomical Society. He observes with a 15” Obsession Classic telescope. Steve has organized several local astronomical events and solar eclipse trips over the years, including Astronomy Day starting in 1980.

Steve and wife Amelia are still very active, supporting various astronomy outreach events in the Greater Houston Area, and Steve is an active promoter of responsible night lighting for Houston. Both Steve and Amelia have a big spot in their hearts for the HAS Dark Site and over the years have been a big part of its development and operation.

Kleb Woods Outreach Report March 29, 2025

Saturday, we had a blast at the Kleb Woods Nature Reserve Astronomy Night – and thanks to the volunteers who helped on short notice, it turned into a superb star party!

This HAS outreach event started with a talk by Erica and Matt on how you measure distances in the universe – a response to a question from one of the young participants at the previous event. We explained the cosmic distance ladder, covering Radar, Parallax, Cepheids, Supernovae, and Redshift. Bats, firetrucks, and thumbs came in handy to walk the kids through how these things work. We measured out cosmic distances by putting the printed numbers on the floor, and there was a lot of excitement when we reached 13.7 billion light-years. Our now-famous Q&A session was just as exciting, as our participants demonstrated unbounded curiosity.

Equipped with star charts, we moved on to the outside star party. Kleb Wood Park is secluded among trees, with a dark enough sky to clearly see the constellations. Thanks to Mark, Ron, Bob, and the loaner telescope Jim arranged for us – we were well-equipped. A 25-inch Obsession with a night vision eyepiece, a 12-inch Dob with a Pi-finder, and the 8-inch Orion equipped with Bob’s eyepiece spectrograph. We showed nebulae, planets, moons, star clusters, and Sirius’ Balmer lines.

It was wonderful to share our excitement about the universe, as both our young and more experienced participants were equally captivated. Kleb Woods Nature Reserve events are quite special; we only have four events per year, and the park is open by exception for Astronomy Night. We now enter our summer (and mosquito) break, but we will return in September. Thank you to our telescope volunteers in particular – the equipment, skill, and excitement you brought to the event turned this into a cosmic spectacle!
