Method to Find New Moons Uncovers Hidden Planet
from the San Francisco Chronicle
The search for distant planets in the Milky Way is now so sophisticated that astronomers are searching for unseen moons around the planets that the Kepler mission's scientists have discovered.
A team of astronomers hunting for those moons reports that in their quest they have unexpectedly detected a hidden planet--and probably two--by using a technique that promises to aid the search for smaller planets much like Earth.
The technique is already in use by the Kepler team at the Ames Research Center in Mountain View, and was being used by astronomers at the Southwest Research Institute in Colorado and Harvard when they detected a curious kink in the orbit of one planet they were tracking in search of a possible "exo-moon."

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
