Planck Mission Peels Back Layers of the Universe
"NASA is pleased to support this important mission, and we have eagerly awaited Planck's first discoveries," said Jon Morse, NASA's Astrophysics Division director at the agency's headquarters in Washington. "We look forward to continued collaboration with ESA and more outstanding science to come."
NASA Telescopes Help Find Most Distant Galaxy Cluster
PASADENA, Calif. -- Astronomers have uncovered a burgeoning galactic metropolis, the most distant known in the early universe. This ancient collection of galaxies presumably grew into a modern galaxy cluster similar to the massive ones seen today.
The developing cluster, named COSMOS-AzTEC3, was discovered and characterized by multi-wavelength telescopes, including NASA's Spitzer, Chandra and Hubble space telescopes, and the ground-based W.M. Keck Observatory and Japan's Subaru Telescope.
"This exciting discovery showcases the exceptional science made possible through collaboration among NASA projects and our international partners," said Jon Morse, NASA's Astrophysics Division director at NASA Headquarters in Washington.

Spitzer Revela el Primer Planeta Rico en Carbono
"Este planeta revela la impresionante diversidad de mundos que hay ahí afuera", afirma Nikku Madhusudhan del Massachusetts Institute of Technology, primer autor de este artículo, publicado en la edición de hoy de la revista Nature. "Los planetas ricos en carbono serían exóticos en todos sus aspectos: formación, interiores y atmósferas".

NASA-Funded Research Discovers Life Built With Toxic Chemical
Researchers conducting tests in the harsh environment of Mono Lake in California have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism substitutes arsenic for phosphorus in its cell components.
"The definition of life has just expanded," said Ed Weiler, NASA's associate administrator for the Science Mission Directorate at the agency's Headquarters in Washington. "As we pursue our efforts to seek signs of life in the solar system, we have to think more broadly, more diversely and consider life as we do not know it."

NASA and NSF-Funded Research Finds First Potentially Habitable Exoplanet
Descubrimiento del primer planeta potencialmente habitable tiene a la ciencia espectante
Un equipo de astrónomos del Instituto Carnegie y la Universidad de California han descubierto un planeta fuera del Sistema Solar que tiene un tamaño comparable a la Tierra y que se encuentra en una zona que podría ser habitable, osea que se encontraría a una distancia de su estrella que le permitiría tener una temperatura adecuada para que haya agua líquida en su superficie. Se trata del Gliese 581g, a solo 20 años luz de distancia y en la constelación de Libra, según publicación de la revista 'Astrophysical Journal'.
