ESO - El frío brillo de la formación estelar

Primera luz de una nueva y potente cámara instalada en APEX

25 de septiembre de 2013

El nuevo instrumento ArTeMiS se ha instalado con éxito en el telescopio APEX — el Atacama Pathfinder Experiment. APEX es un telescopio de 12 metros de diámetro, situado en el desierto de Atacama, que opera en los rangos milimétrico y submilimétrico — en el espectro electromagnético, las longitudes de onda que se encuentran entre el rango infrarrojo y las ondas de radio — ofreciendo una valiosa herramienta a los astrónomos para observar el universo más de cerca. La nueva cámara ya ha proporcionado una espectacular imagen muy detallada de la Nebulosa de la Pata de Gato.

ArTeMiS [1] es una nueva cámara de amplio campo que trabaja en los rangos milimétrico y submilimétrico y que supone un importante complemento a la batería existente de instrumentos con la que ya cuenta el telescopio APEX, ampliando así la profundidad y los detalles de lo que puede observarse. El conjunto de detectores de nueva generación que incorpora ArTeMIS actúa más como una cámara CCD que la generación anterior de detectores. Esto permitirá que los mapas de amplio campo del cielo puedan hacerse con más rapidez y con mayor número de píxeles.

El equipo de puesta a punto (commissioning en inglés) [2] que instaló ArTeMiS tuvo que batallar contra condiciones meteorológicas extremas para completar su tarea. El edificio de control de APEX, en el Llano de Chajnantor, estaba casi enterrado en nieve espesa. Con la ayuda tanto del personal de APEX como de los trabajadores de las instalaciones de soporte a las operaciones de ALMA, el equipo transportó las cajas de ArTeMiS al telescopio a través de un camino improvisado, evitando los ventisqueros de nieve, logrando finalmente instalar el instrumento, maniobrar el criostato hasta dejarlo en la posición correcta y fijarlo a su ubicación definitiva.

Para poner a prueba el instrumento el equipo tuvo que esperar a tener un tiempo muy seco, ya que las ondas submilimétricas de la luz que observa ArTeMiS son absorbidas por el vapor de agua en la atmósfera de la Tierra. Cuando llegó el momento, las observaciones de prueba fueron un éxito. Tras las pruebas y las observaciones de puesta a punto el instrumento ArTeMiS se ha utilizado para varios proyectos científicos. Uno de sus objetivos fue la zona de formación estelar NGC 6334, (la Nebulosa de la Pata de Gato) en la constelación austral de Scorpius (El Escorpión). Esta nueva imagen de ArTeMiS es notablemente mejor que imágenes anteriores obtenidas por APEX de la misma región.

Las pruebas de ArTeMiS se han completado y la cámara viajará de vuelta a Saclay, en Francia, con el fin de instalar detectores adicionales en el instrumento. Todo el equipo está emocionado por los resultados que ya están ofreciendo estas observaciones iniciales, una maravillosa recompensa a los años de duro trabajo que no podría haberse culminado sin el apoyo del personal de APEX.

NASA - NASA Media Resources Available on New International Climate Report

Climate Models Show Potential 21st Century Temperature, Precipitation Changes
New data visualizations from the NASA Center for Climate Simulation and NASA's Scientific Visualization Studio at Goddard Space Flight Center, Greenbelt, Md., show how climate models used in the new report from the United Nations' Intergovernmental Panel on Climate Change (IPCC) estimate possible temperature and precipitation pattern changes throughout the 21st century.

For the IPCC's Physical Science Basis and Summary for Policymakers reports, scientists referenced an international climate modeling effort to study how the Earth might respond to four different scenarios of carbon dioxide and other greenhouse gas emissions throughout the 21st century. The Summary for Policymakers, the first official piece of the group's Fifth Assessment Report, was released Fri., Sept. 27.

This modeling effort, called the Coupled Model Intercomparison Project Phase 5 (CMIP5), includes dozens of climate models from institutions around the world, including from NASA's Goddard Institute for Space Studies.

Models used by the IPCC estimate global temperature and precipitation patterns will change throughout the 21st century given current rising greenhouse gas levels. This video depicts a scenario in which carbon dioxide concentrations reach 670 parts per million by 2100, up from around 400 ppm today.

To produce visualizations that show temperature and precipitation changes similar to those included in the IPCC report, the NASA Center for Climate Simulation calculated average temperature and precipitation changes from models that ran the four different emissions scenarios. The final products are visual representations of how much temperature and precipitation patterns would change through 2100 compared to the historical average from the end of the 20th century.

The changes shown in these maps compare an average of the model projections to the average temperature and precipitation benchmarks observed from 1971-2000. This baseline is slightly different from the baseline used in the IPCC report, which was 1986-2005. Because the reference period from 1986-2005 was slightly warmer than 1971-2000, the visualizations are slightly different than those in the report, even though the same model data is used.

NASA Media Resources Available on New International Climate Report

NASA will make scientists and data visualizations available to journalists Friday, Sept. 27, with the release of a portion of the Fifth Assessment Report from the United Nations' Intergovernmental Panel on Climate Change (IPCC).

The IPCC will issue the "Summary for Policymakers" of the "Physical Science Basis of Climate Change" section of the report in Stockholm on Friday and the full text of that section Monday, Sept. 30. Additional sections will be released in the coming months.
More than 25 NASA scientists helped author and review the Fifth Assessment Report. NASA also will provide unique data visualizations of projected temperature and precipitation changes for the 21st century, based on climate models referenced in the report.
NASA satellite observations, scientific analysis and climate modeling contributed to the report's conclusions on such topics as temperature change, sea level rise, changes to glaciers and ice sheets, and Earth's global energy balance. NASA climate models contributed to the international modeling effort to project climate change throughout the 21st century. NASA scientists also played a key role in evaluating climate model accuracy by comparing models to NASA satellite observations.

nsf.gov - National Science Foundation - NSF awards first coastal sustainability grants for research on world's most populated areas

In wake of storms such as Hurricane Sandy, grants will lead to better management of coastal environments.-

Coastal systems are crucial to regional and national economies.
Credit and Larger Version

September 27, 2013

More than half the world's human population lived in coastal areas in the year 2000; that percentage is expected to rise to 75 percent by 2025.

With our large footprint in coastal sands--and in the wake of severe storms such as Hurricane Sandy--how do we co-exist with our coastlines? How do we use them sustainably?

A sustainable world is one in which human needs are met equitably, without sacrificing the ability of future generations to meet their needs. The National Science Foundation (NSF)'s Science, Engineering, and Education for Sustainability investments aim to address this challenge.

NSF's coastal SEES program is focused on the sustainability of coastal systems: the swath of land closely connected to the sea, including barrier islands, wetlands, mudflats, beaches and estuaries, as well as coastal cities, towns, recreational areas and maritime facilities; the continental seas and shelves; and the overlying atmosphere.

NSF's coastal SEES program has funded its first awards for studies of coasts in the U.S. and around the world. The 11 awards total $13.1 million.

Coastal systems are crucial to regional and national economies. They host human-built infrastructure and provide ecosystem services that sustain our well-being, says David Conover, director of NSF's Division of Ocean Sciences.

"We benefit from coastal environments for enjoyment, housing, food, industrial uses and commerce," says Conover. "In the process, however, we alter them physically, chemically and ecologically."

"These changes influence and interact with natural variability, extreme events and long-term directions to affect the system as a whole, including the benefits humans derive."

We need to better comprehend this coupled human-natural system, he says, so we might make better decisions about its future.

Toward that end, NSF's new coastal SEES projects address topics such as developing high-performance green infrastructure to sustain coastal cities; sustainability of the largest estuary in the U.S., Chesapeake Bay; planning for the hydrologic and ecological effects of sea level rise on coastal water resources; brine discharge from desalination plants; achieving sustainable urban estuaries; and the resilience of coral reefs.

nsf.gov - National Science Foundation - In race against time, NSF grants fund research on Earth's threatened biodiversity

NSF Dimensions of Biodiversity program announces 13 new awards.-

September 27, 2013

The diversity of life on Earth is seemingly endless, yet much still remains to be discovered. With climate change and habitat loss threatening that biodiversity, the challenge of discovery is a race against time.

To fill the gaps in understanding our planet's biodiversity, the National Science Foundation (NSF) has awarded 13 grants totaling $25 million in the fourth year of its Dimensions of Biodiversity program.

Dimensions of Biodiversity is part of NSF's Science, Engineering and Education for Sustainability investment.

Centuries of biological research have established a strong foundation for our understanding of biodiversity.

In the past, however, researchers have sought to understand a single dimension of biodiversity--the diversity of species at the genetic level, species diversity in a taxonomic group, or the diversity of roles certain species play in an ecosystem.

Scientists funded by the Dimensions of Biodiversity program, however, integrate genetic, taxonomic, and functional approaches in their study and exploration.

The Dimensions of Biodiversity awards are supported by NSF's Directorates for Biological Sciences and Geosciences along with NASA, which co-funds projects that use state-of-the-art remote sensing technologies.

Collaborative projects between U.S. and Chinese, and U.S. and Brazilian researchers are co-funded by the National Natural Science Foundation of China (NSFC) and the Sao Paulo Research Foundation (FAPESP), respectively.

"The resulting discoveries go beyond expanding our knowledge of the depth and breadth of life on Earth," says John Wingfield, NSF assistant director for Biological Sciences.

"This research has the potential to revolutionize the way we practice medicine, manage agriculture, address global climate change, and develop new technologies," Wingfield says.

"The synergy created by integrating recent technological advances with collaborations across disciplines and across continents allows these researchers to make significant progress in our understanding of biodiversity."

This year's Dimensions of Biodiversity awardees will study subjects such as: the biota of the critically endangered Brazilian Atlantic forest; microbes living in deep shale deposits; the adaptive radiation of bird lice; the diversity of gut flora in herbivorous woodrats; interactions between floral scents and pollinators; and succession in forests of the Thousand Island lakes area in China .

Grantees will also conduct research on diversification in Adelpha butterflies; nutrient cycling in bivalves' symbiotic organisms; ocean bacteria that help regulate sulfur emissions into the atmosphere; remote sensing technology as a tool for understanding plant and microbial biodiversity; the co-existence of diverse clover species and nitrogen-fixing bacteria; drought tolerance in grasses; and host-viral interactions in hot springs.
