One year ago, an international team of scientists detected the first direct evidence of gravitational waves. UT Austin astronomer Karl Gebhardt recently sat down with the Houston Chronicle's Kim McGuire to talk about his work, which focuses on both black holes and dark energy. He also reflected on the significance of the gravitational wave discovery.

Astronomers at The University of Texas at Austin have developed a new technique to discover the faintest galaxies yet seen in the early universe —10 times fainter than any previously seen.

Two amazing scientific discoveries, both with ties to the College of Natural Sciences at The University of Texas at Austin, were named the top 2 science stories of 2016 by Discover Magazine. Other major media outlets also included them in their year-end "best of" lists, including National Geographic, Science News, Science and the New York Times. A third story from the College of Liberal Arts and Jackson School of Geosciences, which solved the mystery of how the most famous human ancestor died, appears in Discover's top ten as well.

Astronomer J. Craig Wheeler of The University of Texas at Austin thinks that Betelgeuse, the bright red star marking the shoulder of Orion, the hunter, may have had a past that is more interesting than meets the eye. Working with an international group of undergraduate students, Wheeler has found evidence that the red supergiant star may have been born with a companion star, and later swallowed that star. The research is published today in the journal Monthly Notices of the Royal Astronomical Society.

Rolling up your sleeves and putting research to work is a big part of the Longhorn experience. Our students don't just learn about helping people. They are out there making these ideas a reality.

And they need your help.

Steven Weinberg, a Nobel laureate and a professor of physics and astronomy at the University of Texas at Austin, recently discussed some of his concerns about the use and interpretation of quantum mechanics at a gathering of science communicators hosted by the Council for the Advancement of Science Writing (CASW).

​The New Horizons spacecraft brought humanity face to face with the last unexplored planet in our solar system: Pluto. What we're learning is amazing. But, time and again, the mission almost didn't happen. University of Texas at Austin alumnus Alan Stern describes the challenges, and the joys, of the last first mission to a planet.

An international team of astronomers including Michael Endl of The University of Texas at Austin have found clear evidence of a planet orbiting Proxima Centauri, the closest star to the Sun. The long-sought new world, called Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than Earth and is the closest known exoplanet to us — and may be the closest possible abode for life outside our solar system.

Astronomers Aaron Smith and Volker Bromm of The University of Texas at Austin, working with Avi Loeb of the Harvard-Smithsonian Center for Astrophysics, have discovered evidence for an unusual kind of black hole born extremely early in the universe. 

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.
