Habitable worlds with no signs of life.
'Most habitable worlds in the cosmos will have no remotely detectable signs of life' is proposed as a biological hypothesis to be tested in the study of exoplanets. Habitable planets could be discovered elsewhere in the Universe, yet there are many hypothetical scenarios whereby the search for life on them could yield negative results. Scenarios for habitable worlds with no remotely detectable ...
متن کاملExotic Earths: forming habitable worlds with giant planet migration.
Close-in giant planets (e.g., "hot Jupiters") are thought to form far from their host stars and migrate inward, through the terrestrial planet zone, via torques with a massive gaseous disk. Here we simulate terrestrial planet growth during and after giant planet migration. Several-Earth-mass planets also form interior to the migrating jovian planet, analogous to recently discovered "hot Earths....
متن کاملHabitable Worlds: Delivering on the Promises of Online Education.
Critical thinking and scientific reasoning are central to higher education in the United States, but many courses (in-person and online) teach students information about science much more than they teach the actual process of science and its associated knowledge and skills. In the online arena specifically, the tools available for course construction exacerbate this problem by making it difficu...
متن کاملExploring extrasolar worlds: from gas giants to terrestrial habitable planets.
Almost 500 extrasolar planets have been found since the discovery of 51 Peg b by Mayor and Queloz in 1995. The traditional field of planetology has thus expanded its frontiers to include planetary environments not represented in our Solar System. We expect that in the next five years space missions (Corot, Kepler and GAIA) or ground-based detection techniques will both increase exponentially th...
متن کاملSurvival of pediatric blunt trauma patients presenting with no signs of life in the field.
BACKGROUND Prehospital traumatic cardiopulmonary arrest is associated with dismal prognosis, and patients rarely survive to hospital discharge. Recently established guidelines do not apply to the pediatric population because of paucity of data. The study objective was to determine the survival of pediatric patients presenting in the field with no signs of life after blunt trauma. METHODS We c...
