Thousands of Stars Observed Turning into Crystals for the First Time

Stars Observed Turning into Crystals for the First Time

AUSTIN, Texas — 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.

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.

Galactic “Wind” Stifling Star Formation is Most Distant Yet Seen

Galactic “Wind” Stifling Star Formation is Most Distant Yet Seen

AUSTIN, Texas — 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.

McDonald Observatory, Oil and Gas Organizations Collaborate to Protect Night Skies

Collaborating with Oil & Gas Organizations to Protect Night Skies

FORT DAVIS, Texas — The University of Texas at Austin's McDonald Observatory has collaborated with the Permian Basin Petroleum Association (PBPA) and the Texas Oil and Gas Association (TXOGA) to reduce light shining into the sky from drilling rigs and related activities in West Texas. The excess light has the potential to drown out the light from stars and galaxies, and threatens to reduce the effectiveness of the observatory's research telescopes to study the mysteries of the universe.

Texas Researchers Announce Gravitational Wave Event Likely Signaled Creation of a Black Hole

Gravitational Wave Event Likely Created a Black Hole

The spectacular merger of two neutron stars that generated gravitational waves announced last fall likely did something else: birthed a black hole, according to a team of researchers including Pawan Kumar and J. Craig Wheeler of The University of Texas at Austin. This newly spawned black hole would be the lowest mass black hole ever found.
