A fragile atmosphere infused with oxygen and carbon-dioxide has been discovered at Saturn's moon Rhea by the Cassini-Huygens mission - the first time a spacecraft has captured direct evidence of an oxygen atmosphere at a world other than Earth. Published today in Science Express, results from the mission reveal that the atmosphere of Rhea, Saturn's second largest moon at km wide, is extremely thin and is sustained by high energy particles bombarding its icy surface and kicking up atoms, molecules and ions into the atmosphere.
The density of oxygen is probably about 5 trillion times less dense than in Earth's atmosphere. However, the formation of oxygen and carbon dioxide could possibly drive complex chemistry on the surfaces of many icy bodies in the universe. All evidence from Cassini indicates Rhea is too cold and devoid of the liquid water necessary for life as we know it. Dr Geraint Jones, from the UCL Mullard Space Science Laboratory and a co-author of the paper oxygen content of dry air in the atmosphere "The what is a healthy narcissist of this tenuous atmosphere provides key information on how radiation can drive chemistry on icy surfaces throughout the universe.
Rhea's tenuous atmosphere makes it unique in the Saturn system. Titan has a very thick nitrogen-methane atmosphere, with very little carbon dioxide and oxygen. Completing the picture of Rhea's atmosphere, Cassini's ion and neutral mass spectrometer detected neutral particles when Cassini swept within km of the moon's surface in March What is a relationship relation Andrew Coates, also from the UCL Mullard Space Science Laboratory and co-author of the paper, said: "Our instrument turns out to be a fabulous detector of negative ions as well as electrons.
We've already found negative ions are important at Titan and Enceladus - and now, tracing back the trajectory of these ions really pinpoints the source of the atmosphere near Rhea's surface. The ion and neutral mass spectrometer "tasted" peak densities of oxygen of around 50 billion molecules per cubic meter 1 billion molecules per cubic foot. It detected peak densities of carbon dioxide around 20 billion molecules per cubic meter about million molecules per cubic foot.
The plasma spectrometer also saw clear signatures of flowing streams of positive and negative ions, with masses that corresponded to ions of oxygen and carbon dioxide. The carbon dioxide may be the result of "dry ice" trapped from the primordial solar nebula, similar to the case of comets, or it may be due to similar irradiation processes operating on the organic molecules trapped in the water ice of Rhea. The carbon dioxide could also come from carbon-rich materials deposited by tiny meteors that bombarded Rhea's surface.
The finding is consistent with earlier Cassini results that show Rhea to be a particularly dark-looking moon, sporting some carbon-based coating on its surface. Media contact: Clare Ryan. The UCL Mullard Space Science Laboratory delivers a cutting-edge science programme, underpinned by a capability in space science instrumentation, systems engineering and project management.

To be broadcast on television or radio: "tidbits that will air on tonight's 6 o'clock news" Terry Ann Knopf. In this study results indicate that in all cases differences were significant except for types I and III. The density of oxygen is probably about 5 trillion times less dense than in Earth's atmosphere. Frozen in the Ice: Exploring the Arctic. Spatial validity of a forecast model for the daily number of forest fires: Statistical analysis. Initially this is a good result for HI as system to detect fire risk levels. This is a clear case of underprediction. Low stability favors the upward transport of the hot air generated by combustion. The objective of the last ANOVA with year as covariable have been to know if the differences between types and if risk of fire are maintained along years. She gives herself such airs that everyone dislikes her. Goodrick, Evans, N. How does the height of the tropopause normally vary with latitude in the northern hemisphere? Cancelar Comentario. Behavior through which one reveals one's personality: addressbearingdemeanormannermienpresencestyle. Department of National Development. To expose to oxygen content of dry air in the atmosphere air in order to dry, cool, or freshen; ventilate. Atmospheric pressure decreases when altitude increases. Pero este estudio muestra que la baja estabilidad aumenta la actividad de fuego sólo en condiciones atmosféricas de sequedad. These results indicate that confusing results will be produced by mathematical addition of instability and dryness measures. Based on WordNet 3. Vines, Luft lüften Melodie Wetter Atmosphäre. Pregunta 10 de 37 1. Therefore, the results will not be directly evaluated for such conditions. High values of D indicate a dry air mass.

What is the rate of decrease of temperature with height per m in the International Standard Atmosphere? While it is theoretically possible to use multiple variables directly to assess fire risk, weighing the variables is too complex for operational application. In low stability conditions a larger volume of air to the oxygen content of dry air in the atmosphere is brought to upper levels by turbulence and vertical mixingwhich favor a renovation of air around the initial ignition point. In this paper we have used the GD and Haines indices. Of or relating to the broadcast or transmission of radio or television signals. La baja estabilidad favorece superiority meaning in telugu transporte hacia arriba del aire caliente generado en la combustión. This study further served to confirm the earlier results found for the GD model, using an independent data set.

Yousuff Hussaini, P. Under dry conditions fire activity is increased by instability, but under moist conditions it is decreased. Discussion According to the GD model results of Table Armosphere and Figure 3if humidity is assumed as the primary factor for determining fire activity, stability plays a very important role as an authentic contentt of the fire occurrence. Corke, N. The saturation deficit D is given by:. The gaseous mixture enveloping the earth: atmosphere. More interesting results appear when the influence of stability is analyzed.

Once upon a time there lived a Fairy who had power over the earth, the sea, fire, and the air ; and this Fairy had four sons. Every one knows that oxgyen the peculiar cunning of their gills, the finny tribes in general breathe the air which at all times is combined with the element in which they swim, hence, a herring or a cod might live a century, and cohtent once raise its atmosphhere above the surface. Therefore, only low stability increases fire activity on dry days. Meteorologists collect information about weather conditions. Therefore, it could be concluded that low stability favors fire development. Meteorology is the study of different atmospheric variables to make weather predictions.

The carbon dioxide may be the result of "dry ice" trapped from the primordial solar nebula, similar to the case of comets, or it may be due to similar irradiation processes operating on the organic molecules trapped in the water ice of Rhea. If air is under moist conditions, it will not dry fuels, in fact it can even make them wet, thus, reducing fire risk. Rivas Soriano, F.
