Teardrop Trail Log: March 29, 2016

We headed south to the McDonald Observatory, located in the mountains of West Texas. At an elevation of 6719 feet, it is under some of the darkest skies in the continental United States.

My introduction to the Observatory came through the StarDate radio broadcasts on Public Radio. At last, we were driving up Dark Sky Drive on Mt. Locke towards the Visitors Center. We had reservations for a 2:00 pm solar viewing and tour. We met our tour guide and enjoyed the solar program in the visitors center for an up-close look at the large research telescopes. We took the shuttle to the top of Mt. Locke and the overlook of the 107″ dome.

After sharing the history of the Observatory, the guide took our group to the lobby and we climbed the four flights of stairs. He described the parts of the telescope, the functions and how the astronomers use it.

The most exciting parts of the demonstration were when he showed the telescope’s motions and then rotated the dome. We felt the power of the motors that moved the large structure. 

Hobby-Eberly Telescope

The next part of the tour continued at the summit of Mt. Fawkes and the Hobby-Eberly Telescope. The guide explained that an amazing collaboration between four universities allowed this telescope to be built at 80% of the cost of an optical telescope of similar size. The primary mirror is the largest yet constructed making it one of five biggest telescopes in the world. Renovations have just been completed for a new cutting-edge research project, Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). It is the quest to understand dark energy, the mysterious force that makes up 70 percent of the matter and energy in the universe.

We were hoping to attend one of the “Star Parties,” later that evening but the forecast called for cloudy skies so we headed back to Balmorhea and our teardrop.
