Model Suggests Ocean Currents Shape Europa’s Icy Shell in Ways Critical for Potential Habitats

Model Suggests Ocean Currents Shape Europa’s Icy Shell in Ways Critical for Potential Habitats

In a finding of relevance to the search for life in our solar system, researchers at The University of Texas at Austin’s Institute for Geophysics, the Georgia Institute of Technology, and the Max Planck Institute for Solar System Research have shown that the subsurface ocean on Jupiter’s moon Europa may have deep currents and circulation…   » Continue Reading

“Out of Whack” Planetary System Offers Clues to a Disturbing Past

“Out of Whack” Planetary System Offers Clues to a Disturbing Past

The discovery of a planetary system “out of whack,” where the orbits of two planets are at a steep angle to each other, was reported today (May 24) by a team of astronomers led by Barbara McArthur of The University of Texas at Austin McDonald Observatory. This surprising finding will affect theories of how multi-planet systems evolve and shows that some violent events can happen to disrupt planets’ orbits after a planetary system forms, say researchers.

McDonald Observatory Scientist Details ‘Planets Gone Wild’; Reporters May Participate Remotely in Live Webcast from Miami

Event: McDonald Observatory's Barbara McArthur gives a press briefing live from the 216th meeting of the American Astronomical Society in Miami on her surprising findings about a nearby solar system obtained with Hubble Space Telescope, The University of Texas at Austin's giant Hobby-Eberly Telescope in West Texas, and other ground-based telescopes. The university will issue…   » Continue Reading

Texas Astronomer Makes First Ground-Based Detection of Extra-Solar Planet Atmosphere, Using Hobby-Eberly Telescope

University of Texas at Austin astronomer and Hubble Fellow Seth Redfield has used the Hobby-Eberly Telescope (HET) at McDonald Observatory to make the first ground-based detection of the atmosphere of a planet outside our solar system.
