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.

Video - HAS Novice Meeting - May 7, 2026 - "Navigating the Spring Sky"

“Navigating the Spring Sky”

By Chris Morisette

By May we are “knee-deep” into Galaxy Season.  In “Navigating the Spring Sky” Chris Morisette will present various references and methods to help you find your way around the cosmos.  In particular we’ll see how we can use The Big Dipper as a “signpost”, which will allow us to find and view several beautiful celestial objects, including some very cool galaxies.

Speaker Bio: Chris Morisette is HAS Novice Chairperson and an active member of the Houston Astronomical Society, North Houston Astronomy Club, and the Fort Bend Astronomy Club.  He is also a member of The University of Texas at Austin McDonald Observatory and Department of Astronomy Board of Visitors.

AP Target of the Month - Apr 2026 -M64

 AP SIG TOTM is out! M64: a striking spiral galaxy in Coma Berenices, famous for its dark “black eye” dust lane cutting across the bright core. Located ~17 million light-years away, it shows evidence of counter-rotating gas, likely from a past galactic merger. A great target in broadband, with OIII, Halpha and... can you catch the IFN?

 

Video - HAS Novice Meeting – April 2, 2026 - "Calendar Systems"

“Calendar Systems”

By Deborah Moran

 

There is no easy mathematical relationship between the lengths of the solar day, the orbit of the Moon around the Earth and the orbit of the Earth around the sun.  How different civilizations dealt with this conundrum when devising their calendars is an adventure.  Learn about the Julian calendar, the Gregorian calendar, the Jewish and Islamic calendars and the Chinese calendar.  

 

Speaker Bio: Deborah Moran developed a lifelong interest in astronomy living in Midland, TX as a child where all the scenery is in the sky. She has been a member of the Houston Astronomical Society since 1980, where she has served in a number of capacities in the past including Treasurer, Education chair and nine years as Novice chair in charge of talks for new members.  She continues to speak frequently in the community on astronomy topics and light pollution.  She is also a volunteer telescope operator at the George Observatory in Brazos Bend State Park.  She actively fights light pollution in Houston and was awarded the Dark Sky International’s Hoag-Robinson Award in 2017 for her efforts.  She has combined her love of travel and astronomy by chasing total and annular solar eclipses around the world. She retired from the Houston Symphony violin section after 27 years in 2010.

AP Target of the Month - Mar 2026 -Deep Space

Galaxy season gives us a rare window to peer past the Milky Way into the true depth of the universe. This month's AP SIG Target of the Month is a challenge: capture a deep field. Integrate long enough into a seemingly empty patch of sky and watch distant galaxies reveal themselves. Tools like "What's in My Image" in Seti Astro Suite or PixInsight are great for exploring what you've captured. How deep can you go?
