Supernova Reveals Secrets to Texas-led Team of Astronomers

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.

Two NASA Post-Doctoral Fellows Coming to UT Austin

Two NASA Post-Doctoral Fellows Coming to UT 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 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.

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.

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 Discover Strangely Massive Black Hole in Milky Way Satellite Galaxy

Astronomers Discover Strangely Massive Black Hole in Milky Way Satellite Galaxy

McDonald Observatory astronomers have found that Leo I (inset), a tiny satellite galaxy of the Milky Way (main image), has a black hole nearly as massive as the Milky Way's. Leo I is 30 times smaller than the Milky Way. The result could signal changes in astronomers' understanding of galaxy evolution. Credit: ESA/Gaia/DPAC; SDSS (inset)

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.

Astronomers Disprove Planet Orbiting Nearby Barnard’s Star

Astronomers are announcing today that they have disproved a 2018-announced planet orbiting Barnard's Star, the second-closest star to our Sun. The findings, based on observations with the Habitable Zone Planet Finder (HPF) instrument on the 10-meter Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory, have been accepted for publication in The Astronomical Journal.
