Editor’s Note: Today’s post comes to you from Rebecca Johnson, Editor of the StarDate Magazine at the McDonald Observatory.
A year-long celebration is underway to celebrate the 75th anniversary of the University of Texas at Austin’s McDonald Observatory, with the first event of 2014 being held at HMNS on Tues., Jan. 14 with a public lecture by Dr. Jon Winget.
Dubbed “impossible stars,” white dwarfs are the simplest stars with the simplest surface chemical compositions known — yet they are very mysterious. The McDonald Observatory leads in investigating white dwarfs along several avenues: telescope observations, theory, and most recently, the making of “star stuff,” using the most powerful X-ray source on Earth at Sandia National Laboratory.
Dr. Don Winget, one of the world’s leading experts on white dwarfs, will give a Distinguished Lecture at HMNS to examine the how studies of these stars can shed light on everything from the age of the universe to the understanding of dark matter and dark energy.
Located near Fort Davis, Texas, under the darkest night skies of any professional observatory in the continental United States, McDonald Observatory hosts multiple telescopes undertaking a wide range of astronomical research. McDonald is home to the consortium-run Hobby-Eberly Telescope (HET), one of the world’s largest, which is being upgraded to begin the HET Dark Energy Experiment. An internationally known leader in astronomy education and outreach, McDonald Observatory is also pioneering the next generation of astronomical research as a founding partner of the Giant Magellan Telescope. The McDonald Observatory was dedicated May 5, 1939, and has supported some of the most important astronomical discoveries of recent decades about everything from extrasolar planets to exotic stars and black holes.
The Observatory plans a full year of activities around the state to celebrate. Events will run through August 2014, including a lecture series featuring McDonald Observatory astronomers in multiple cities and an Open House at the Observatory.
The celebration continues at the observatory’s website. Visitors to the anniversary pages can peruse a timeline of observatory history, watch several historical videos, and share their memories and photos of McDonald on an interactive blog called “Share Your Story.”
