AUSTIN — A team of astronomers led by Andrew Mann of The University of Texas at Austin has confirmed the existence of a young planet, only 11 million years old, that orbits extremely close to its star (at 0.05 AU), with an orbital period of 5.4 days. Approximately five times the size of Earth, the new planet is a "super-Neptune" and the youngest such planet known. The discovery lends unique insights into the origin of planetary system architectures.

For most of their lives, galaxies are lush environments for turning gas into stars. Until they aren’t.

AUSTIN — Astronomer Brendan Bowler of The University of Texas at Austin has been awarded a competitive Hubble Fellowship from NASA and the Space Telescope Science Institute (STScI), science center for the Hubble Space Telescope.

“I congratulate Brendan Bowler on winning one of the most prestigious fellowships in astronomy to continue his work at McDonald Observatory," said Taft Armandroff, the observatory’s director.

AUSTIN — University of Texas at Austin astronomer Andrew Mann and colleagues have discovered a planet in a nearby star cluster which could help astronomers better understand how planets form and evolve. The discovery of planet K2-25b used both the Kepler space telescope and the university’s McDonald Observatory, and is published in a recent issue of The Astrophysical Journal.

AUSTIN — High school senior Dominick Rowan of Armonk, New York, is making discoveries about other worlds. Working with University of Texas at Austin astronomer Stefano Meschiari, Rowan has helped to find a Jupiter-like planet and has calculated that this type of planet is relatively rare, occurring in three percent of stars overall.

AUSTIN — University of Texas astronomer Natalie Gosnell has used Hubble Space Telescope to better understand why some stars aren’t evolving as predicted. These so-called “blue stragglers” look hotter and bluer than they should for their advanced age. It’s almost as if they were somehow reinvigorated to look much younger than they really are.

AUSTIN — A study published in today’s Astrophysical Journal by University of Texas at Austin assistant professor Steven Finkelstein and colleagues reveals that galaxies were more efficient at making stars when the universe was younger. The announcement explains the team’s discovery, announced in the journal’s September 1 issue, that there are a lot more bright, highly star-forming galaxies in the early universe than scientists previously thought.

ATACAMA DESERT, Chile — Leaders and supporters from The University of Texas at Austin’s McDonald Observatory, along with representatives from an international group of partner universities and research institutions, are gathering on a remote mountaintop high in the Chilean Andes today to celebrate groundbreaking for the Giant Magellan Telescope (GMT).
