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.

On April 15, The University of Texas at Austin announced its 2025 Outstanding Staff Awards. Thirty-one staff members were selected from a highly competitive pool of nominations. Among those to receive the honor is McDonald Observatory Engineering Scientist John Good.

In March, the Space Telescope and Science Institute announced the selection of 274 programs for the fourth year of observations on its James Webb Space Telescope (JWST). This includes approximately 8,500 hours of observing time. Of that, a whopping 10 percent (over 800 hours) was awarded to programs led or co-led by astronomers at The University of Texas at Austin.

With support from the Kavli Foundation, the Vice Presidents of the American Astronomical Society (AAS) name a special invited lecturer to kick off each semiannual AAS meeting with a presentation on recent research of great importance. At the 246th AAS meeting in Anchorage, Alaska, on 9 June 2025, the Fred Kavli Plenary Lecture will be given by Dr.

The 2025 Board of Visitors Winter Meeting took place February 28 and March 1 on The University of Texas at Austin campus. Over 140 members and guests joined us for a reception at the Texas Science & Natural History Museum, the latest news from UT and BOV leadership, and a showcase of the pioneering work underway at the Department of Astronomy and McDonald Observatory.

The Flame Nebula, located about 1,400 light-years away from Earth, is a hotbed of star formation less than 1 million years old. Within it, there are objects so small that their cores will never be able to fuse hydrogen like full-fledged stars — brown dwarfs. Astronomers have long debated how small brown dwarfs can be. Now, a new study sheds light on this question by finding the lowest mass brown dwarfs yet.

UT Austin’s Caroline Morley is among the prestigious group of astronomers selected by Research Corporation for Science Advancement (RCSA) for the first year of its Scialog: Early Science with the LSST award.

In December 2022, less than six months after commencing science operations, NASA’s James Webb Space Telescope revealed something never seen before: numerous red objects that appear small on the sky, which scientists soon called “little red dots” (LRDs). Though these dots are quite abundant, researchers are perplexed by their nature, the reason for their unique colors, and what they convey about the early universe.

Protecting the night sky is a collaborative endeavor - one The University of Texas at Austin’s McDonald Observatory has helped lead in West Texas since the launch of its Dark Skies Initiative in 2010. Now, oil and gas facilities in nearby New Mexico are joining the effort, with help from a new set of lighting guidelines tailored to their industry.

The University of Texas at Austin joined the Giant Magellan Telescope today in announcing that Northwestern University has joined its international consortium to construct the $2.54 billion observatory.
