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. more..
For most of their lives, galaxies are lush environments for turning gas into stars. Until they aren’t. Over the last few billion years, a mysterious kind of “galactic warming” has turned huge numbers of galaxies into deserts devoid of fresh young stars. The puzzle for astronomers has been identifying the unknown process that keeps the gas in these dormant galaxies too hot and energetic to form stars. Today, astronomers from the Sloan Digital Sky Survey (SDSS), including Dr. Niv Drory of The University of Texas at Austin, are announcing the discovery of a new class of galaxies called "red geysers" that harbor supermassive black holes with winds that have the power to keep dormant galaxies quiet. more..
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. Hubble Fellows conduct research related to the mission of NASA’s Cosmic Origins Program, which aims to examine the origins of galaxies, stars, and planetary systems, and the evolution of these structures with cosmic time. more..
