In the late 1990s, the University of Washington created what was arguably the world’s first graduate program in astrobiology, aimed at preparing scientists to hunt for life away from Earth. In 2001, David Catling became one of the first people brought to the UW specifically to teach astrobiology.

Catling, a UW professor of Earth and space sciences, is the author of Astrobiology: A Very Short Introduction, the 370^th offering in the Oxford University Press series of “very short introduction” books by experts in various fields. Catling was commissioned by editors to write the book, which was published in the United States on Jan. 1. Following are his answers to some questions about the book and astrobiology. (more…)

Water Geysers on Saturn’s Moon

A new study published in Nature this week describes the forces that control the jets of water and organic material that erupt from the icy surface of Enceladus, a moon of Saturn. UA scientists contributed data to the study.

The intensity of the jets of water ice and organic molecules that shoot out from Saturn’s moon Enceladus depends on the moon’s proximity to the planet, according to data obtained by NASA’s Cassini spacecraft. The finding, detailed in the journal Nature this week, is the first clear observation that shows the Enceladus plume varies in a predictable manner. (more…)
