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.

Throughout its 70-year history, public astronomy outreach events have been a major priority of HAS. This it is clearly stated in our mission statement “Fostering the science and art of astronomy through programs that serve our membership and the community.” With 5 regular star parties and a few other similar events officially reported or not, HAS reaches over 5,000 people a year in our area.

Most amateur astronomers are passionate about our hobby, and this passion leads many to share their joy of observing the night sky with others. The positive feedback we get from the public, and the excitement we see in the faces of the school children we introduce to the night sky motivates some to find ways to organize new astronomy outreach events in new locations beyond friends and family.

For those who are new to amateur astronomy, participating in organized outreach events is a great way to learn by trying different instruments that may also include smart telescopes. By participating in outreach events, you will also meet and establish relationships with other HAS members who can help you along your journey in amateur astronomy.

At our November 6th regular meeting, we will hold a panel discussion about astronomy outreach. You will meet several of our members who are fully involved in doing astronomy outreach in different ways and at different locations. Each of them will describe what they do to engage the public and introduce them to the night sky. They will also explain why they are so dedicated to Outreach.

HAS Regularly Scheduled Outreach Events to be presented are:

STEM In The Park, Rustic Oaks Park, League City -Dan Roy

Dan Roy is currently HAS Outreach Coordinator. Dan is happily retired in League City TX where he leads monthly STEM parties (microscopy and astronomy) for the park services and volunteers for the Foundation for International Space Education (FISE) United Space School (USS) program which brings 50 most brilliant kids from 25 countries to Houston for an intensive workshop about the space program.

Astronomy in the Park – Memorial Park Eastern Glades

Joyce & Matt Almaguer-Reisdorf

Joyce and Matt coordinate the regular HAS public outreach program at Memorial Park. Matt is an engineer in the energy business working on both fossil fuels and renewables. Joyce has a background in ecology and appreciates seeing astronomy as an extension of the wonderful natural world here on Earth.

Outreach at Challenger 7 Memorial Park

Michael Segura

Michael Segura is a retired Navy nurse with a lifelong passion for astronomy. He is a regular feature of Astronomy and Microscopy in the park in League City and leads our monthly event at the Challenger 7 Memorial Park in Webster often with his wife Amy.

Mike has the most impressive collection of optical instruments from spotting scopes to an 8” Dobs. He also owns a few binoculars and somehow manages to show them all at once to the public.

John Paul Landing Park – Bill Spizzirri

Bill Spizzirri is a retired computer software engineer who has been studying astronomy for over 65 years. His favorite thing to do is to teach astronomy to the public, especially children. He has been doing that more or less continuously for over 40 years. He now does it at Houston area schools and community centers. The pay is excellent, in the form of great questions from the students.

Matt and Erica organize the four annual astronomy outreach nights at Kleb Woods Nature Preserve near Tomball. They enjoy sparking people’s curiosity and encouraging them to explore the night sky for themselves. Matt is the HAS President, and Erica serves on the board as Membership Chair. Both work in Houston’s energy industry and enjoy exploring everything from astrophotography and radio astronomy to data science.

“Aurora: The Science Behind Nature’s Light Show”

By Peggie Mueller

The aurora has fascinated observers for millennia, inspiring myths and prompting questions about its origins. Since the 1960s, observations from spacecraft, satellites, and ground-based observatories have greatly advanced our understanding of the physical processes responsible for auroral displays. A commonly cited definition describes an aurora as a natural light display in Earth’s upper atmosphere caused by charged particles from the Sun colliding with atmospheric atoms. This talk examines how our current understanding of the Sun-Earth connection challenges and extends this simplified description, exploring the complex processes that ultimately produce auroral emissions.

Speaker Bio: I have been a member of the Houston Astronomical Society since 2021. My desire to understand the mechanisms that generate the aurora deepened after viewing and photographing the Northern Lights in Lofoten, Norway and in Finnish Lapland. While I find the beauty of auroral displays to be captivating, I consider the science behind the aurora just as fascinating.

People have always been fascinated with the rings of Saturn. Per ChatGPT (Ok, I'm cheating):

Galileo Galilei was the first person to observe Saturn's rings in 1610 using a telescope.

However, Galileo's telescope was not powerful enough to show the rings clearly. He thought Saturn had two large companions on either side.

Christiaan Huygens, a Dutch astronomer, correctly explained the rings in 1655. He proposed that Saturn was surrounded by a thin, flat ring that did not touch the planet.

Here is a composite image of Saturn from 2018 to 2026 showing how the rings appear to us on Earth. Saturn’s rings appear to open and close because Saturn is tilted on its axis as it orbits the Sun, changing the angle at which we see the rings from Earth.

“Navigating the Autumn Sky”

By Heather Charron

With cooler nights ahead (hopefully) autumn is great time to get out under the stars as a cornucopia of beautiful and exotic deep sky objects present themselves. We will provide a brief review on how to navigate the night sky using celestial signposts and take us on a tour of the autumn night sky.

Speaker Bio: Heather Charron

Heather joined HAS in December 2023, the newly formed AP-SIG group in 2024, and volunteered to reboot the GuideStar newsletter in 2025. She is now beginning her visual astronomy journey with a 10-inch Zhumell on loan from the HAS loaner library.
