To get to the National Radio Telescope Observatory, you have to be committed.
Well, first, you have to be in New Mexico -- about an hour's drive south of Albuquerque, in the plains of San Augustin, to be precise, a Pleistocene lakebed bordered by the northern end of the Chihuahuan Desert and dotted with arid shrubs. Despite being some 6,970 feet above sea level, it feels like the basement of the world, wide and flat and under the massive Southwestern sky. Driving to the Observatory, the home of the famous "Very Large Array" of radio telescopes, is an exercise in…

Bethany Ehlmann Nick Anthis: Would it be possible to briefly take our readers through the history of the discovery of water (or traces of past water) on Mars? I know that this is an important area, but it seems like there's so much work on it coming out now that it's hard for someone not in the field to put it all into context. Maybe you could just…
scientificactivist | July 30, 2008Planetary geology is a fascinating area--particularly when it pertains to the search for extraterrestrial life. I wrote about it once during my brief stint as a student science writer, but it's not an area that I've really covered on my blog. However, a former colleague of mine from Oxford, Bethany Ehlmann, was recently involved with a couple of papers on geological formations left by ancient Martian water, so I thought that this would be a perfect opportunity. Ehlmann is currently a PhD student in the geological sciences at Brown University and part of the CRISM (Compact Reconnaissance…
