Would you like to help astronomers understand more about the universe? McDonald Observatory astronomers are trying to learn more about dark energy — the mysterious force causing the universe to expand faster and faster over time. And now there is a fun and easy way anyone can help with their research, using a smartphone or computer.

Astronomers at The University of Texas at Austin are set to lead some of the largest programs in the first year of NASA's James Webb Space Telescope (JWST), including the largest project overall. Set to launch this Halloween, the telescope will become operational by mid-2022. Altogether, UT astronomers received about 500 hours of telescope time in JWST's first year.

FORT DAVIS, Texas — Just in time for International Dark Skies Week (April 5-12), McDonald Observatory is announcing a new program to honor West Texas businesses and organizations for Night Skies Friendly Lighting practices. These practices keep light on the ground and out of the sky, helping to preserve the exceptional night skies for which far West Texas is famous.

Two UT Austin postdoctoral scientists, Brianna Lacy and Yifan Zhou, have received the 51 Pegasi b Fellowship from the Heising-Simons Foundation, which will provide them with support for research focused on planets that orbit a star outside our solar system, known as exoplanets. Zhou is supervised by Brendan Bowler, an assistant professor of astronomy, and Lacy will be supervised by Caroline Morley, also an assistant professor of astronomy.

The University of Texas at Austin and other partners of the Giant Magellan Telescope (GMT) announce the fabrication of the sixth of seven of the world's largest monolithic mirrors. These mirrors will allow astronomers to see farther into the universe with more detail than any other optical telescope before. The sixth 8.4-meter (27.5 feet) mirror — about two stories high when standing on edge — is being fabricated at The University of Arizona's Richard F. Caris Mirror Lab and will take nearly four years to complete.

​​Four faculty members from the University of Texas at Austin's College of Natural Sciences have received 2021 Sloan Research Fellowships, which honor outstanding early-career scientists in eight fields.

The American Astronomical Society (AAS), the major organization of professional astronomers in North America, has honored Anita Cochran, assistant director of McDonald Observatory and senior research scientist, for extraordinary achievement and service by naming her an AAS Fellow for 2021.

A group of astronomers from The University of Texas at Austin has found that a telescope idea shelved by NASA a decade ago can solve a problem that no other telescope can: It would be able to study the first stars in the universe. The team, led by NASA Hubble Fellow Anna Schauer, will publish their results in an upcoming issue of The Astrophysical Journal.

When scientists first detected gravitational waves, from the violent collision of two black holes 1.3 billion years in the past, the ripples in space-time made a distinctive chirp, followed by a signal like a ringing bell. (The signals actually had to be converted into frequencies we can hear.) Since that first detection in 2015, every black hole collision has sounded pretty much the same. But according to a new study based on computer simulations, black holes actually sing a more elaborate swan song.

​The GMTO Corporation has received a $17.5 million grant from the National Science Foundation (NSF) to accelerate the prototyping and testing of some of the most powerful optical and infrared technologies ever engineered. These crucial advancements for the Giant Magellan Telescope (GMT), of which The University of Texas at Austin is a founding partner, will allow astronomers to see farther into space with more detail than any other optical telescope before.

An international team of astronomers has used NASA's Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope to discover what may be the first intact planet found closely orbiting a white dwarf, the dense leftover of a sun-like star only 40% larger than Earth. The work, led by Andrew Vanderburg of The University of Texas at Austin, included follow-up observations with the 10-meter Hobby-Eberly Telescope at the university's McDonald Observatory.

The University of Texas at Austin's McDonald Observatory is planning to reopen to the public, in a limited fashion, on Friday, Aug. 28. Beginning with a star party that night, the observatory's Frank N. Bash Visitors Center will begin holding public programs again.

A team of astronomers including McDonald Observatory's Bill Cochran have made a detailed study of a young planet slightly smaller than Neptune with the Habitable-zone Planet Finder at The University of Texas at Austin's McDonald Observatory. They characterized the planet's mass, radius, and the tilt of its orbit. This work provides insight into how such planets form and evolve, and has been accepted for publication in the Astronomical Journal.
