Colloquium Series Lecture: Starship Life Support

March 30th, 2010

Dr. Jones will report on the design and cost of a starship, with emphasis on life support systems. He will describe a multigenerational interstellar voyage to colonize a new planet. Nuclear propulsion is required. The mission is more feasible if a small crew travels slowly and lands with minimal equipment. Growing food is about as […]

Ashes to Ashes, Dust to Dust

March 30th, 2010

This new composite image from NASA’s Chandra X-ray Observatory and Spitzer Space Telescope shows the dusty remains of a collapsed star, the dust from which is flying past and engulfing a nearby family of stars. Scientists believe the stars in the image are part of a stellar cluster in which a supernova exploded. Material ejected in the explosion now blows past these stars at high velocities. In this image of G54.1+0.3, X-ray data from Chandra are shown in blue, and data from Spitzer in green (a shorter wavelength) and red-yellow (a longer one). The white source near the center of the image is a dense, rapidly rotating neutron star, or pulsar, all that remains of a core-collapse supernova explosion. The pulsar generates a wind of high-energy particles — seen in the Chandra data — that expands into the surrounding environment, illuminating the material ejected in the supernova explosion. The unique environment into which this supernova exploded makes it possible for astronomers to observe the condensed dust from the supernova that is usually too cold to emit in the infrared.

CSE SETI Institute Colloquium Series

March 29th, 2010

What clays can tell us about past climate at Mawrth Vallis, Mars Nancy McKeown Mawrth Vallis has one of the largest exposures of phyllosilicates on Mars. Originally observed by OMEGA, CRISM has refined the detections and allowed positive identification of several phyllosilicate minerals including nontronite, montmorillonite, and kaolinite, as well as hydrated silica, based on […]
