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. The club meets on the first Friday of each month at the University of Houston. Membership has a variety of benefits, including access to a secure dark site west of Houston, a telescope loaner program, and much more. Joining our club is simple; you can sign up online, by mail or in person at a monthly meeting.

January 26, 2012, 7:30PM: 2012 Inaugural Urban Observing Star Party

Please join your fellow HAS members for our first Urban Star Party of 2012! We're meeting at Bear Creek Park; directions below, follow this link for a Google Map.

Directions: Turn south off of Clay Road, into the park onto Bear Creek Drive. This is at the northeast corner of the golf course, so you will have park on the left and golf course on the right. The very first left is North Schulz Lane and the next left is South Schulz lane. Turn left on South Schulz Lane, which immediately has parking on both sides.

We will set up on the picnic area on the south side, just north of the bathrooms, which are close to the big pavilion number 6.

In the event of cancellation due to weather, a notice will be sent via the HAS netslyder email system and the STARLINE (832-464-4270) will be updated at 6:00PM advising of the events status, either canceled or that it will still be held.

January 24th and 31st: Basic Observational Astronomy Course

Did you get a new telescope or pair of binoculars over the holidays? The Houston Astronomical Society is offering a two-night introductory class for new observers. You will learn about the sky, what’s waiting for you to see, and how you can enjoy the night sky.

Our first class to be offered will be held starting on January 24, 2012 and January 31, 2012, from 7:00 to 9:30 PM.

February 03, 2012: The Planetary Evolution of Mars: Insights from Old and Young Martian Meteorites

Novice Meeting: 7:00PM
Novice Meeting Topic: 
Skytools Part I: Introduction to Skytools
Novice Meeting Speaker: 
Steve Goldberg
General Meeting: 8:00PM
General Meeting Topic: 
The Planetary Evolution of Mars: Insights from Old and Young Martian Meteorites
General Meeting Speaker: 
Tom Lapen, The University of Houston
About the General Meeting Presentation

Tom Lapen will present recent research of martian meteorites that constrain important planetary-scale processes including the initial formation and differentiation of Mars to much more recent volcanism on Mars.

Parking and Directions (View Map)

Meetings are held in the Science & Research building at the University of Houston Main Campus. The novice meeting is in room 116, the general meeting is in room 117.

Do not try to park around any of the old parking lots due to the construction on the new parking garage. Drive a short distance down Cullen to Parking lot 15D or 15F which is were they have moved the staff parking lot (the gates will be open). DO NOT PARK IN ANY OF THE ASSIGNED STAFF PARKING SPACES; The assigned staff parking spaces will be noted like the old parking lot with number parking painted on the ground. Normally, this will be the FIRST and SECOND rows. Jefferson stadium is the home stadium for the Houston Dynamo soccer team and on Friday nights of their home games please let the parking attendant know you are there for the HAS monthly meeting and you wont have to pay parking.

Shallow Sky Object of the Month: M44

Re-thinking an Alien World: The Strange Case of 55 Cancri e

Original article appears in GuideStar December, 2011.

55 Cancri eForty light years from Earth, a rocky world named “55 Cancri e” circles perilously close to a stellar inferno. Completing one orbit in only 18 hours, the alien planet is 26 times closer to its parent star than Mercury is to the Sun. If Earth were in the same position, the soil beneath our feet would heat up to about 3200 F. Researchers have long thought that 55 Cancri e must be a wasteland of parched rock.

Now they’re thinking again. New observations by NASA's Spitzer Space Telescope suggest that 55 Cancri e may be wetter and weirder than anyone imagined.

Spitzer recently measured the extraordinarily small amount of light 55 Cancri e blocks when it crosses in front of its star. These transits occur every 18 hours, giving researchers repeated opportunities to gather the data they need to estimate the width, volume and density of the planet.

Shallow Sky Object of the Month: Double Cluster—NGC 884 / 869

Original article appears in GuideStar December, 2011.

Double ClusterThese two clusters are a magnificent site in binoculars or a wide-field telescope. The picture to the right is from TheSky X software, and the light blue circle is one degree on the sky. So, you need optics that will provide a visual field of at least one degree to get both clusters in the field.

A small refractor on a dark night would be a good instrument to use on this pair of clusters. It turns out that the new moon this December is on the 24th, Christmas eve. If you’re with your friends and family on that night, this would be a great object to show them in your telescope. On that night the Double Cluster will be about 62 degrees above the horizon, and it will transit at 8:35 p.m.

Chris Westall and Lennie Brown: A GuideStar Interview

Original article appears in GuideStar December, 2011.

Clayton JeterI first met Chris Westall two years ago at the dedication of the Blinn College Schaefer Observatory” and star party in Schulenburg, Texas. I had recently restored the college’s ‘70s-era Celestron C-14 Schmidt-Cassegrain telescope. While operating the refurbished SCT that evening under the dome, I was introduced to Chris.

Some months later, I discovered that Chris had formed a new astronomy club in the La Grange area (halfway between Houston and Austin). He invited me to a star party at Lennie Brown’s Bed and Breakfast near La Grange and I have since joined their group, the “Colorado Valley Dark-Sky Explorers”. These two folks are the heartbeat of the astronomy community in their area.

This is a very informal group that loves the night skies. They have several observing sites and always seem to have a star party pending. Let’s see how a new local club came to be and what makes it tick…
