Mars may once have been awash in water but the water was very salty
Oct. 26,
2009 -- Andrew H. Knoll, Ph.D., Fisher Professor of Natural History and professor of earth and planetary sciences at Harvard University, will discuss the evidence for life on Mars at 7 p.m. Oct. 30 in Room 300, Laboratory Sciences Building, on the Danforth Campus of Washington University in St. Louis.

Putting a new spin on an old technique, Anne M. Hofmeister, Ph.D., research professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has revolutionized scientists' understanding of heat transport in the Earth's crust, the outermost solid shell of our planet.

U.S.-led team confirms an Alps-like mountain range exists under east Antarctic ice sheet
Capstone of NSF-supported International Polar Year
Feb. 25,
2009 --
Flying twin-engine light aircraft the equivalent of three trips around the globe and working in temperatures that averaged minus 30 degrees Celsius, an international team of scientists, including one from Washington University in St. Louis, has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice. Douglas A. Wiens, Ph.D., WUSTL professor and chair of earth and planetary sciences, is part of the seismology team.

A seismologist at Washington University in St. Louis along with colleagues at Pennsylvania State University and Newcastle University in the United Kingdom have found seismic signals from a giant river of ice in Antarctica that make California's earthquake problem seem trivial. Douglas A. Wiens, Ph.D., professor of earth and planetary sciences in Arts & Sciences, and colleagues combined seismological and global positioning system (GPS) analyses to reveal two bursts of seismic waves from an ice stream in Antarctica every day, each one equivalent to a magnitude seven earthquake.

Missouri earthquake awareness month
Seminar to address ways to lessen earthquake damage
Feb. 6,
2008 -- The Department of Mechanical, Aerospace and Structural Engineering at Washington University in St. Louis is presenting a series of seminars and workshops on the topic of reducing the damage that would occur when a strong earthquake strikes the New Madrid fault area again.

| Thick or thin ice shell on Jupiter's moon Europa? Scientists are all but certain that Europa has an ocean underneath its surface ice, but do not know how thick this ice might be. |

Jupiter's moon Europa is just as far away as ever, but new research is bringing scientists closer to being able to explore its tantalizing ice-covered ocean and determine its potential for harboring life. William B. McKinnon, professor of earth and planetary sciences at Washington University in St. Louis, is discussing some of these recent findings and new opportunities for exploring Europa in a news briefing on Thursday, Dec. 13, 2007, at the meeting of the American Geophysical Union in San Francisco.

Hot spot on Enceladus causes plumes

| Hot spots on Saturn's tiny satellite, Enceladus, could be telltale signs of life on the frigid moon. |

Enceladus, the tiny satellite of Saturn, is colder than ice, but data gathered by the Cassini-Huygens Mission to Saturn and Titan has detected a hot spot that could mean there is life in the old moon after all. In fact, for researchers of the outer planets, Enceladus is so intellectually hot, it's smokin'.
