AUSTIN — Astronomers from The University of Texas at Austin and colleagues have used the 2.1-meter Otto Struve Telescope at the university’s McDonald Observatory to discover pulsations from the crystalized remnant of a burnt-out star. The finding will allow astronomers to see below the star’s atmosphere and into its interior, much like earthquakes allow geologists to study compositions below Earth’s surface. The findings appear in the current issue of The Astrophysical Journal Letters.

Event: McDonald Observatory astronomer Matthew Shetrone and Artistic Director Keith Knopp of Yellow Barn offer insight into the science and art behind popular and classical music in an afternoon presentation followed by a discussion. In the late evening, Yellow Barn percussionists perform Le Noir de l'Etoile, a work celebrating the discovery of pulsars.

Paul R. Shapiro, the Frank N. Edmonds, Jr., Regents Professor in Astronomy at The University of Texas at Austin, has been elected to a four-year term to the Chair line of the Division of Astrophysics of the American Physical Society.

The American Physical Society (APS) is the principal professional society in physics in North America. Its Division of Astrophysics represents more than 2,400 scientists working in many fields of astrophysics and cosmology.

AUSTIN — Today, the Texas House of Representatives and Senate will honor The University of Texas at Austin’s McDonald Observatory for 75 years of discovery. The observatory’s 75th anniversary is coming up in May 2014.

 A proclamation sponsored by State Representative Poncho Nevárez (District 74, which includes Jeff Davis and surrounding counties in west Texas) will be read in the House Chamber at approximately 10 a.m.

 At approximately 11 a.m., a resolution sponsored by State Senator José Rodríguez of El Paso will be read in the Senate Chamber.

LONG BEACH, Calif. — The American Astronomical Society has awarded Sally Dodson-Robinson, assistant professor of astronomy at The University of Texas at Austin, its Annie Jump Cannon Award for outstanding research and promise for future research by a woman. The prize was awarded at the society's 221st semiannual meeting in Long Beach, California.

Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system’s formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.

The discovery by astronomers at the University of California, Berkeley, and Clarion University in Pennsylvania of six likely comets around distant stars suggests that comets — dubbed “exocomets” — are just as common in other stellar systems with planets. 

AUSTIN, Texas — Seven faculty members at The University of Texas at Austin, including Dr. Neal Evans II of the Astronomy Department, have been elected fellows of the American Association for the Advancement of Science (AAAS). Fellows are chosen annually by their peers to recognize their scientifically or socially distinguished efforts to advance science or its applications.

Fort Davis, Texas — Astronomers have used the Hobby-Eberly Telescope at The University of Texas at Austin's McDonald Observatory to measure the mass of what may be the most massive black hole yet — 17 billion Suns — in galaxy NGC 1277. The unusual black hole makes up 14 percent of its galaxy's mass, rather than the usual 0.1 percent. This galaxy and several more in the same study could change theories of how black holes and galaxies form and evolve. The work will appear in the journal Nature on Nov. 29.

AUSTIN, Texas — J. Craig Wheeler has studied the exploding stars called supernovae for more than four decades. Now he has a new idea on the identity of the "parents" of one of the most important types of supernovae — the Type Ia, those used as "standard candles" in cosmology studies that led to the discovery of dark energy, the mysterious force causing the universe's expansion to speed up. 

The first mirror for the Giant Magellan Telescope (GMT), a major next-generation telescope in which The University of Texas at Austin is a founding partner, is now completed. 

Becoming operational in the next decade under dark southern-hemisphere skies, GMT will lead a new generation of giant telescopes that will explore planets around other stars and the formation of stars, galaxies and black holes in the early universe.
