The Butterfly Nebula, located about 3,400 light-years away in the constellation Scorpius, is one of the best-studied planetary nebulae in our galaxy.
Friday, July 25, through Saturday, July 26, McDonald Observatory hosted the annual Board of Visitors Summer Meeting. Featuring science talks, discussion groups, and telescope tours and viewings, the event connected almost 200 attendees with the latest astronomical research. Although there were minor bouts of stormy weather, each evening the clouds cleared to reveal clear views of the night sky.
Astronomers have discovered a remarkably clumpy rotating galaxy that existed just 900 million years after the Big Bang, shedding new light on how galaxies grew and evolved in the early universe.
An international team of astronomers, led by UT Austin’s Cosmic Frontier Center, has identified the most distant black hole ever confirmed. It and the galaxy it calls home, CAPERS-LRD-z9, are present 500 million years after the Big Bang. That places it 13.3 billion years into the past, when our universe was just three percent of its current age. As such, it provides a unique opportunity to study the structure and evolution of this enigmatic period.
Researchers at The University of Texas at Austin, UC Santa Barbara, Yale University, and National Taiwan Normal University have found that a fair number of Sun-like stars emerge with their rotational axis tilted with respect to their protoplanetary disks, the clouds of gas and dust from which solar systems are born.
On Friday, July 25, representatives from Austin Bat Refuge in Austin, Texas, will be onsite at McDonald Observatory in Fort Davis, Texas, to release a Big Freetail bat back into the wild. Named Hubble after the famous astronomer, he is thought to have accidentally hitched a ride from the Observatory to Austin in some astronomy gear. Big Freetail bats do not live in Central Texas but are a common sight in the Big Bend region, where the Observatory is located.
The University of Texas at Austin is on track for huge leaps forward in astronomy research capabilities. The Giant Magellan Telescope (GMT) has received official approval from the National Science Foundation (NSF) confirming that the observatory will advance into its Major Facilities Final Design Phase, one of the final steps before becoming eligible for federal construction funding. This critical milestone recognizes the Giant Magellan’s scientific merit, construction progress, and alignment with U.S. priorities in science and technology.
COSMOS-Web provides the most expansive and deepest observations of the universe to date. Now, the team behind this work - which includes several members from The University of Texas at Austin - has released the data and images associated with its full survey, all processed and ready for analysis (see images, specifically, here).
The Cosmic Frontier Center in The University of Texas at Austin’s Department of Astronomy is proud to announce its second class of postdoctoral fellows. The three Frontier Fellows were selected from a competitive pool of 73 applicants. Joining the center in the fall of 2025, their work will support its mission to uncover the origin of galaxies, black holes, and stars in the early universe.
An international team of scientists, including from McDonald Observatory at The University of Texas at Austin, has discovered a potentially star-forming cloud that is one of the largest single structures in the sky and among the closest to the Sun and Earth ever to be detected.
The cloud of gas is located about 300 light years away. Scientists estimate that it would look vast to stargazers on Earth - if it were visible - measuring about 40 moons across the sky. Its mass is estimated as roughly 3,400 times that of the Sun.
