Scientists have uncovered what sets the masses of stars, a mystery that has captivated astrophysicists for decades. Their answer? Stars, themselves.Using highly detailed simulations, a collaborative team led by researchers from the University of Texas at Austin has made a breakthrough discovery that star formation is a self-regulatory process, knowledge that may allow researchers to understand star formation within our own and far away galaxies. Read more

Two new images from NASA's James Webb Space Telescope show what may be among the earliest galaxies ever observed. Both images include objects from more than 13 billion years ago, and one offers a much wider field of view than Webb's First Deep Field image, which was released amid great fanfare July 12.

AUSTIN, Texas — The Giant Magellan Telescope (GMT) is a next-generation optical/infrared telescope being developed in northern Chile that will yield important discoveries on topics such as galaxies in the early universe and Earth-sized planets orbiting nearby stars.

The University of Texas at Austin is investing an additional $45 million in the GMT, the world’s most powerful telescope. This additional funding brings the university’s total commitment to $110.3 million.

FORT DAVIS, Texas – West Texas and the Big Bend region are known for their starry night skies, made possible in part due to ongoing efforts to preserve them. Recently, McDonald Observatory and the non-profit organization Texan by Nature recognized the efforts of Catalyst Midstream Partners (“Catalyst”), a joint venture between Howard Energy Partners (“HEP”), and Devon Energy Corporation (“Devon”), to reduce light emissions at their County Line Processing Plant near Orla, Texas.

AUSTIN — An international group of astronomers led by Benjamin Thomas of The University of Texas at Austin has used observations from the Hobby-Eberly Telescope (HET) at the university’s McDonald Observatory to unlock a puzzling mystery about a stellar explosion discovered several years ago and evolving even now. The results, published in today’s issue of The Astrophysical Journal, will help astronomers better understand the process of how massive stars live and die.

FORT DAVIS, Texas — The University of Texas at Austin’s McDonald Observatory will hold its first Dark Skies Festival Friday, April 29, and Saturday, April 30. The festival will include daytime and evening events for the whole family, plus the debut of the new “Preserving Dark Skies” exhibit in the Frank N. Bash Visitors Center. Both the exhibit and the festival are funded by Apache Corporation.

FORT DAVIS, Texas, U.S. and COAHUILA, Mexico — The University of Texas at Austin’s McDonald Observatory, The Nature Conservancy – Davis Mountain Preserve, and the International Dark-Sky Association (IDA) are pleased to announce the certification of the Greater Big Bend International Dark Sky Reserve. The designation, granted by the International Dark-Sky Association, recognizes the commitment of organizations, governments, businesses and citizens in the region to maintain dark skies.

AUSTIN — NASA has selected 24 new Fellows for its prestigious NASA Hubble Fellowship Program (NHFP), two of whom are heading to The University of Texas at Austin. The program enables outstanding postdoctoral scientists to pursue independent research in any area of NASA astrophysics, using theory, observations, simulations, experimentation, or instrument development. Each fellowship provides the awardee up to three years of support at a university or research center of their choosing in the United States.

The Fellows coming to UT are:

AUSTIN — Astronomer Stella Offner of The University of Texas at Austin has been awarded the NCU-Delta Young Astronomer Lectureship Award by Taiwan’s National Central University and the Delta Electronics Foundation.

Each year, the award is given to one or two international scholars under the age of 45. It includes an invitation to deliver a series of prize lectures in Taiwan and a trophy. Representatives from Delta Electronics presented the award to Offner in Austin yesterday.

Renowned engineering and architecture firm, IDOM, faces rigorous design requirements of the Giant Magellan Telescope’s enclosure to allow for unobstructed observations of the night sky.
