The first direct evidence of crystallized white dwarf stars has been discovered by an international team of researchers that includes an astronomer at The University of Texas at Austin. Predicted half a century ago, the direct evidence of these stars will be published tomorrow in the journal Nature.

In findings published today in The Astrophysical Journal, University of Texas at Austin astronomers report that they have stumbled on an extraordinary galaxy that may corroborate a recently contested theory about dark matter.

StarDate Radio Program Celebrates 40 Years

StarDate Radio Program Celebrates 40 Years

Award winning radio program StarDate turns 40 years old

The longest running nationally aired science program is marking a major milestone. "StarDate" radio, produced by The University of Texas at Austin's McDonald Observatory, celebrates 40 years on the nation's airwaves. In its nearly 15,000 daily two-minute episodes, "StarDate" has brought skywatching and astronomy to millions of listeners across the United States. Today, it airs on about 400 radio affiliates, split evenly between public and commercial stations.

Magnetic Waves Create Chaos in Star-Forming Clouds

Magnetic Waves Create Chaos in Star-Forming Clouds

New research by Stella Offner, assistant professor of astronomy at The University of Texas at Austin, finds that magnetic waves are an important factor driving the process of star formation within the enormous clouds that birth stars. Her research sheds light on the processes that are responsible for setting the properties of stars, which in turn affects the formation of planets orbiting them, and, ultimately, life on those planets. The research is published in the current issue of the journal Nature Astronomy.

For the first time, a powerful "wind" of molecules has been detected in a galaxy located 12 billion light-years away. Probing a time when the universe was less than 10 percent of its current age, University of Texas at Austin astronomer Justin Spilker's research sheds light on how the earliest galaxies regulated the birth of stars to keep from blowing themselves apart. The research will appear in the Sept. 7 issue of the journal Science.

A new scientific facility is under construction on the grounds of The University of Texas at Austin's McDonald Observatory that will help scientists better understand Earth and could help minimize the effects of geohazards such as earthquakes, volcanic eruptions, sea level changes and landslides.

The University of Texas at Austin's McDonald Observatory today shared in announcing the start of hard rock excavation for the Giant Magellan Telescope's (GMT's) massive concrete pier and the foundations for the telescope's enclosure on its site at Las Campanas Observatory in Chile. McDonald Observatory is a founding partner of the international collaboration building the GMT, which will be the world's largest telescope when completed in the next decade.
