Central Texas Star Party 2025 Image

Join us for CTSP 2025!

It’s that time of year! Time for our annual Central Texas Star Party, also known as CTSP! Dunno what that is? Well here’s the first round of details….

All About CTSP!

CTSP is AAS’s annual member gathering, education, and star party! While it is member-focused, anyone can join us, and the Saturday astro activities are FREE!
Over September 19th and 20th, we’ll be out at Pedernales State Park at the Star Theater where our AAS observatory is located. It’s the park’s observing area as well, so park rules do apply! There will be limited camping spots at the side of the Star Theater’s field. It’ll be very important to prepare for CTSP, if you’re coming for the day or camping on the field, or elsewhere in the park. As it’s an active field, Dark Sky field protocol and Star Party Etiquette both apply.

Please note: non-members must pay park entrance fees, and the member dinner and field camping will not be available.

What Happens at CTSP?

Part of the fun of CTSP is to meet and connect with members and the amazing knowledge within the club.
We’ll have our potluck on Friday evening, which is always a lot of fun. Bring a dish to share with the group, and share stories about our astronomical escapades.
On Saturday, participants engage in solar viewing, observatory work and improvements, observatory training, a variety of astro-topical sessions, our onsite swap meet, or individual projects as needed – it really is a great time to ask questions and get pointers! And yes, new AAS members, we encourage you to come out too, even if you don’t have a scope. No matter – come meet astronomy fans like you, and enjoy the night sky with fellow members.
Saturday late afternoon, members take a pause for our member BBQ. The BBQ is $12 for adults and $7 for youth, and comes with all of the trimmings. There will be a members-only link for signup for the BBQ – stay tuned for that in the next posts!
The evening follows on with more observing, well into the night.
On Sunday, folks pack up and head home, making sure we leave the park as we found it.

Preparing for CTSP

We’ll share more later, but as it’s late summer in Central Texas, you HAVE to prepare for CTSP! Bring your astro-gear, but also bring a canopy, chairs, cool clothes, hat, plenty of food for meals, snacks, ice, any medicines, and lots and lots of water! If you sign up with member services for a spot on the field, please bring your self-sufficient tent preparations. Definitely sunscreen or bug spray, but do that far away from any scopes or gear and definitely do not touch anything!
We’d also recommend leaving pets at home, but bring family. 🙂
That’s it – make sure you check out the upcoming mails, the posts here, and on our socials. We look forward to seeing everyone at CTSP 2025!
Clear Skies!

Featured Speaker on Friday, 11 August General Assembly Meeting

Our featured speaker this month is Dr. Madhan R. Tirumalai Ph.D.who will have a few things to say about
discovering oceans on distant planets in his talk:

ExoOceans, Icy Moons: Space Exploration and Planetary Protection

 

The past couple of decades has seen an explosion in our knowledge of planets beyond our solar system.
So far, a few thousand have been identified. Questions that until recently were relegated to science
fiction have now taken on a new urgency. What are the conditions necessary for life and even
civilizations on alien worlds? With improved technology, we are just becoming able to detect, from light
years distance, markers that could indicate if a planet might support life.

For life as we know it, water is essential, but for readers of Frank Herbert’s Dune series, it seems human
life might be adaptable to a very wide range of available moisture. Contrast Herbert’s Caladan, home
world of house Atreides an ocean world, to Arrakis a desert world where the story unfolds. Now, think
about the difficulties in colonizing next door Mars.
If ever we are going to make the investment in journeying to an extra solar world, you can bet that we
would likely only move toward a planet with an ocean.

Monthly Meeting Friday August 10 th
Practical Astronomy 6:30 and General Meeting 7:30

Join us Friday night at 7:30 for this exploration of the science and science-fiction of life beyond
planet Earth.

Last Fast Track: Myth and Sky, April 7th!

myth sky astronomy public membersHi everyone –

Please join us for our last Fast Track event of the season – Myth and Sky! We’ll do it jointly with the Public Star Party at Pedernales Falls State Park on April 7th. We’ll skywalk the Spring sky, learn pointers, talk about the major constellation fields, and deep sky objects of interest. Once we’re done sky walking and discussing mythology, culture, and how stories show in the stars, stay for viewing with the public. Bring your telescope!

This will take place in combination with the public event which starts earlier. The fast track portion will start after dark.


Come explore the wonders of the night sky at a public star party at Pedernales Falls State Park on Saturday, April 7th.

FREE with the cost of park entry, safe solar viewing and dark sky activities will kick off from 6 to 7:30 pm. Night sky observing and other activities will run from 8 to 10 pm.

Co-Hosted by the Texas Night Sky Festival® Team and Austin Astronomical Society, the festivities will take place at the Pedernales Falls Star Theater, adjacent to the Equestrian Area in the park. Parking will be available near the activity area which is adjacent to the Star Theater.

From the park entrance follow the yellow arrows to the park headquarters, denoted with a red dot on the map above, to obtain your park entry permit. Then proceed to the Star Theater, highlighted in blue on the map at http://cdn.austinastro.org/…/Pedernales-Falls-State-Park.png

In case of inclement weather, a “Go” or “No Go” notification will be posted on our Texas Night Sky Festival Facebook page at https://www.facebook.com/TexasNightSkyFestival/ by 2 p.m. on the day of the party.

This event is the first of many star party events which will be hosted via a new partnership between Austin Astronomical Society and Pedernales Falls State Park. This public star party has the added attraction of having activities brought to you by the Texas Night Sky Festival® Team, which is comprised of representatives from the Hays County Chapter Texas Master Naturalists, IDA Texas and the City of Dripping Springs.

Weather permitting, it will be an excellent family-friendly activity for all ages to experience.

The Return of the Messier Marathon! Members’ Night, March 17th

March and Early April are one of the most amazing times in the celestial calendar. In the Northern Hemisphere (depending your latitude), on nights from late March through to the first couple of weeks of April, astronomers can view a good rotation of the night sky. If you’re intrepid, from dawn to dusk, there’s the opportunity to see ALL of the objects in Messier’s catalog!

M1 – M110 will be available, but it is a challenge to see them all. But, many amateur astronomers have taken up this challenge – to see all 100, or at least a majority of them, during a 10-11hr window. There IS a real strategy to achieve this goal, but it is doable! It is a real testament to an astronomer’s stamina, astronomical planning, observing, and logging skills to achieve it.

Austin Under the Stars 2017

Austin Astronomical Society (AAS), in collaboration with St. Stephen’s Episcopal School, brings to the public Austin Under the Stars (AUTS). AUTS is designed to bring the spectacles of the night sky to the Austin Metropolitan community. This special event, free of charge, is scheduled from 6:00 p.m. to 11:59 p.m. on Saturday, July 29 and will take place on the St. Stephen’s Campus off of Capital of Texas Highway at 6500 St. Stephen’s Drive 78746.

Joining AUTS for the tenth year in a row are the folks of the Texas Museum of Science and Technology. They will be providing 20 minute shows in their mobile planetarium and will be on hand to answer any questions about the their latest exhibits and shows.
