Who We Are

The South Texas Astronomical Society (or STARS) is a Brownsville community-based nonprofit organization focusing on space science research, education, and outreach.

Our Mission

To elevate space science initiatives and connect educators and experts directly to the people who need them most: students, amateur astronomers  and community members with a shared interest in space.

Our People

STARS is a product of the community — comprised of local businesses, organizations, and space enthusiasts that help us achieve our goal of fostering a community through astronomy and space.

Our Work

 We organize and promote astronomy and space science-related community events to educate and engage the public in everything Brownsville has to offer as a Space City.

Projects & Initiatives

Dark Sky

Preserving the night sky in local parks such as Resaca De La Palma State Park (home to the Cristina Torres Memorial Observatory) is a crucial part of maintaining some of our country’s most beautiful and distinctive places right here in South Texas.


STARS is helping to restore a Solar System Walk (or planet walk) located on the Texas Southmost College (TSC) campus. This to-scale model will be accompanied by a virtual online library of planetary information, including facts and resources from NASA and other educational institutions.


STARS is working with community partners to build a world-class science center in the heart of downtown Brownsville  to showcase local talent and serve as a home for space science education and communication in the Rio Grande Valley and beyond.

Observatory Restoration

 In collaboration with our partners at the Brownsville Public Library, STARS is helping to restore and upgrade the Southmost Public Library Observatory for future star parties and joint observations for scientific research with UTRGV’s Cristina Torres Memorial Observatory!
