Welcome to Houston Astronomical Society

Founded in 1955, Houston Astronomical Society is an active community of enthusiastic amateur and professional astronomers with over 60 years of history in the Houston area. Through education and outreach, our programs promote science literacy and astronomy awareness. We meet on the first Friday of each month at the Trini Mendenhall Community Center. Membership has a variety of benefits, including access to a secure dark site west of Houston, a telescope loaner program, and much more. Joining is simple; you can sign up online, by mail or in person at a monthly meeting.

“Navigating the Spring Sky”

Outreach report for Valentine’s event at the Schaefer Observatory

Friday night could not have been better weather for a public observing event. Folks seemed to know it, too, as they travelled to Schulenburg from as far away as the east side of Houston. Inside a warm classroom, I gave a brief talk about what we were going to see, and why, to a couple of dozen stargazers ranging in age from 3 to 63. For this crowd, Lepus became the Bunny Rabbit and Orion the Hunter was armed with shield and club. We did have several teenagers, so Messier 35 in Gemini became Castor’s toe ring. One 12-year-old boy didn’t see the Big Dipper asterism rising in the north but the Rocket Ship! You can see it, too, if you extend the end stars of the dipper bowl to the snout of the Big Bear. I told him I’d be using that asterism of his from now on.

We continued with questions as we walked across the Blinn College parking lot to line up with South Street, a straight as an arrow boulevard running east to west and conveniently lined with large oak trees. After pointing out Venus blinding us from above, we started navigating down to Mercury which had just crested a tree and was making its way front and center. Not many in humanity have seen Mercury so one-by-one the adults and teens thrilled to spot it. It took a little while for the under 12 crowd, but parents would not give up until their children had seen it too. My funny wizard hat saved the day for one mom as she was able to position me so that Mercury was at the hat’s tip and lifted her son to her eye level to spot it. “Oh, that orange dot?” And after a chuckle, we moved on to the observing field.

Winter is a great time to talk stellar evolution while pointing out naked eye objects like the Pleiades—stars in their childhood; the Hyades—teenaged stars who prefer some distance but still hang out together; and, of course, the most spectacular stellar nursery the night sky affords us—the Great Orion Nebula. Winter is not known for globular clusters, but Lepus came to the rescue with Messier 79 to round out the other end of the stellar life cycle. Equipped with printed Skymaps, clipboards, soft pencils and red flashlights, we began the constellation tour... click read more button 

Get your observing on!

In my personal opinion, the greatest benefit of membership in HAS is the access to our Dark Site.  One thing I see so often on astronomy forums is people like us who live in urban areas talking about the things they have to deal with when trying to do astronomy from dark locations.

StephenJones.jpgThings like needing portable power packs, to dealing with critters, local law enforcement, or even yokels with guns.  On top of this, many of these people, especially in the Northeast, have to drive for 3+ hours just to get to a site decently dark enough for deep-sky astronomy.  How fortunate we are that we don’t have to deal with any of these things.  

The HAS Dark Site is an hour or less from parts of the West side of the metro area and no more than 2 hours from the furthest reaches of the East side.  It has all of the amenities you need for observing: solid ground to set your scope on, electricity, restrooms, bunkhouses to sleep in, a legal right for you to be there, and no one waving a gun in your face (critters can be a wild card, but they tend to stay away too).  There’s even telescopes you can borrow out there.  There are also all kinds of great events going on at the Dark Site throughout the year, like the Messier Marathon, Annual Picnic, and other great events put on by Jim King, our Field Trip and Observing Chair, as well as my Novice Lab program.

But there’s also no need to wait for an event to get out there!  Remember, your membership gets you 24-7 access to the dark site (with completion of the orientation, of course).  If the conditions are good there’s bound to be someone out there.  If you’re still worried about being there by yourself, connect with other members! Several folks, including myself, will frequently post to the email server or to the Facebook group when we are heading out there.  Feel free to send a post out there yourself if you’re thinking of going... click read more button

Asterisms - Coat Hanger, Collinder 399

Asterism: a grouping of stars that form a recognizable pattern.

Constellation: Vulpecula
Right Ascension: 19 h, 26 m 12s
Declination: 20o 06’ 00”
Magnitude:  3.6
Size: 60’ (minutes)

The “Coat Hanger” is a group of stars in the constellation Vulpecula, between Cygnus and Sagitta. It is easily located between the star Albireo in Cygnus and the 2 brightest stars in Sagitta: Alpha and Beta. This open cluster has the official names of Collinder 399 (CR 399) and OCL 113 (Open Cluster). ... click read more button
