Just milliseconds after the universe's Big Bang, chaos reigned. Atomic nuclei fused and broke apart in hot, frenzied motion. Incredibly strong pressure waves built up and squeezed matter so tightly together that black holes formed, which astrophysicists call primordial black holes.
Scientists have uncovered what sets the masses of stars, a mystery that has captivated astrophysicists for decades. Their answer? Stars, themselves.
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. The images represent some of the first out of a major collaboration of astronomers and other academic researchers teaming with NASA and global partners to uncover new insights about the universe.
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.
What starts here reveals the universe. A world-changing gift of $10 million from visionary philanthropist David Booth increases UT's access to the Giant Magellan Telescope, which will help students in the College of Natural Sciences peer far into the universe.
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.
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 world's largest International Dark Sky Reserve is coming to Texas and Mexico, thanks to a partnership between The University of Texas at Austin's McDonald Observatory, The Nature Conservancy, the International Dark-Sky Association (IDA) and many others. The designation, granted by the IDA, recognizes the commitment of organizations, governments, businesses and residents in the region to maintaining dark skies. The move will benefit not only astronomical research, but also wildlife, ecology and tourism.
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.
The partners of the Giant Magellan Telescope (GMT) today announced they have awarded IDOM, a renowned engineering and architecture firm based in Spain, a contract to complete the telescope enclosure design by 2024. The award follows an extensive enclosure designer evaluation and selection process based on a detailed set of criteria involving design team experience, proposed approaches to specific design challenges, incorporation of safety management in the design process, and more. The University of Texas at Austin is a founding partner of the GMT.
Brendan Bowler, an assistant professor of astronomy from the University of Texas at Austin's College of Natural Sciences has been selected as a 2022 Alfred P. Sloan Research Fellow in Physics.
After more than three decades of sharing astronomy with the public and working to protect dark skies from light pollution, Bill Wren has retired from McDonald Observatory.
In the course of research for his Ph.D., Zach Vanderbosch spent nearly 300 nights studying the heavens from telescopes at The University of Texas at Austin's McDonald Observatory. Later this month, he will receive his doctorate for his research into the dead stars known as white dwarfs, and the orbiting disks of debris made up of these stars' former planets.
Astronomers at The University of Texas at Austin's McDonald Observatory have discovered an unusually massive black hole at the heart of one of the Milky Way's dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies — the building blocks of the universe — evolve. The work is published in a recent issue of The Astrophysical Journal.
Read our publication, The Texas Scientist, a digest covering the people and groundbreaking discoveries that make the College of Natural Sciences one of the most amazing and significant places on Earth.
