We have obtained HST-NICMOS observations of five of M31's most metal-rich globular clusters: G1, G170, G174, G177 & G280. For the two clusters farthest from the nucleus, G1 and G280, we statistically subtract the field population and estimate metallicities using K-(J-K) color-magnitude diagrams (CMDs). Based on the slopes of their infrared giant

The MELISSA Pilot Plant laboratory provides the site where the different advances around the Micro Ecological Life Support System Alternative project coordinated and fostered by the European Space Agency, as well as other associated technologies, are integrated and demonstrated. During its first period of operation, the definition of the different

The Earthshine project, was run by California Institute of Technology (Caltech) between 1993 and 1995. Since 1998, it has been a collaborative effort between Caltech and Big Bear Solar Observatory (BBSO)/New Jersey Institute of Technology (NJIT). Our primary goal is the precise determination of a global and absolutely calibrated Earth's albedo and

The Earthshine project is a collaborative effort between Big Bear Solar Observatory (New Jersey Institute of Technology) and the California Institute of Technology. Our primary goal is the precise determination of a global and absolutely calibrated Earth's albedo and the characterization of its synoptic, seasonal and inter-annual variability
