Astronomers at The University of Texas at Austin's McDonald Observatory, along with colleagues at Caltech and elsewhere, have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid belt to out beyond Neptune. Other giant planets with highly elliptical orbits have been found around other stars, but none of those worlds were located at the very outer reaches of their star systems like this one.

The New Voice of StarDate

StarDate Radio is announcing today that Billy Henry is the program's new voice. Henry, an Austin-based voice talent, musician, composer, and college lecturer, becomes the third narrator of the program in its 41-year history. He assumes the title from Sandy Wood, who retired from the program yesterday. Henry's first program airs today.

AUSTIN, Texas — The University of Texas at Austin's McDonald Observatory is celebrating its 80th anniversary, and it started today with an event at the Capitol. Senate Concurrent Resolution No. 60, authored by Texas state Sen. José Rodríguez to honor the anniversary, passed this morning on the Senate floor. Texas state Rep. Poncho Nevárez will sponsor the resolution in the House. Located near the West Texas town of Fort Davis, McDonald Observatory falls into the districts of both lawmakers.

Undergraduate-Led Team Discovers Two New Planets Using Artificial Intelligence

Undergraduate-Led Team Discovers Two New Planets Using Artificial Intelligence

Undergraduate astronomy student Anne Dattilo and colleagues used artificial intelligence to discover two exoplanets in data collected by the Kepler space telescope.

Astronomers at The University of Texas at Austin, in partnership with Google, have used artificial intelligence (AI) to uncover two more hidden planets in the Kepler space telescope archive. The technique shows promise for identifying many additional planets that traditional methods could not catch.

A new astronomical spectrograph provides the highest precision measurements to date of infrared signals from nearby stars, allowing astronomers to detect planets capable of having liquid water on their surfaces that orbit cool stars outside our solar system. The Habitable Zone Planet Finder (HPF) allows precise measurement of a star's radial velocity, measured by the subtle change in the color of the star's spectra as it is tugged by an orbiting planet, which is critical information in the discovery and confirmation of new planets.

The first direct evidence of crystallized white dwarf stars has been discovered by an international team of researchers that includes an astronomer at The University of Texas at Austin. Predicted half a century ago, the direct evidence of these stars will be published tomorrow in the journal Nature.

StarDate Radio Program Celebrates 40 Years

Award winning radio program StarDate turns 40 years old

The longest running nationally aired science program is marking a major milestone. "StarDate" radio, produced by The University of Texas at Austin's McDonald Observatory, celebrates 40 years on the nation's airwaves. In its nearly 15,000 daily two-minute episodes, "StarDate" has brought skywatching and astronomy to millions of listeners across the United States. Today, it airs on about 400 radio affiliates, split evenly between public and commercial stations.
