NOAO da el visto bueno para que el proyecto BigBoss use 500 noches de observación en el telescopio Mayall, en Arizona, con el objetivo de elaborar el mapa más detallado del firmamento e investigar la historia de la expansión del universo y de la energía oscura

Con una resolución que supera los tres billones de píxeles, la imagen cubre un tercio del cielo nocturno y ha permitido el hallazgo de casi 500 millones de objetos astronómicos.

Entre otros, el satélite aporta nueva información sobre la radiación de microondas emitida por el Big Bang, traza un catálogo de nubes donde se originarán nuevas estrellas e identifica numerosos cúmulos de galaxias

In this work we present the first complete CO J=3-2 map of M 81, observed as part of the Nearby Galaxies Legacy Survey. M 81 is a nearby spiral galaxy (3.64 Mpc) known for hosting a high level of star formation. Previous studies, mainly in the J=1-0 line, have found little CO. The CO measured in a galaxy allows, through an empirical conversion factor, to know its content of molecular hydrogen. We have detected nine regions of important emission in the CO J=3-2 line, located at different regions of the spiral arm and confirmed that the global CO emission is low. Using a new Halpha map

The extragalactic background light at far-infrared ( FIR) wavelengths comes from optically faint, dusty, star-forming galaxies in the Universe with star formation rates of a few hundred solar masses per year. These faint, submillimetre galaxies are challenging to study individually because of the relatively poor spatial resolution of far-infrared telescopes but they are responsible for more than 85% of the total extragalactic intensity at these wavelengths. Instead, their average properties can be studied using statistics such as the angular power spectrum of the background intensity

We find a distinct stellar population in the counterrotating and kinematically decoupled core of the isolated massive elliptical galaxy NGC 1700. Coinciding with the edge of this core, we find a significant change in the slope of the gradient of various representative absorption line indices. Our age estimate for this core is markedly younger than the main body of the galaxy. We find lower values for the age, metallicity, and Mg/Fe abundance ratio in the center of this galaxy when we compare them with other isolated elliptical galaxies with similar velocity dispersion. We discuss the
