Reports on the detection of local and global modulations of star formation in galaxies are reviewed and compared to results from semi-analytic models. The latter are used for the following main objectives, i) to study the expected extent of the...

Stardust, the NASA comet sample return mission, obtained thousands of particles from comet Wild 2. Detailed laboratory study of this material from a body that formed beyond Neptune is providing new insight into the origin of comets and crystalline...

Major surveys have now thoroughly sampled the galaxy population at redshifts below z ~ 1.4. This talk will summarize broadly what has been learned about galaxy evolution over these epochs, focussing on results from DEEP2 and Sloan. The main...

A massive black hole resides in the center of most, perhaps all galaxies. The one in the center of our home galaxy, the Milky Way, provides a uniquely accessible laboratory for studying in detail the connections and interactions between a massive...

For a decade, high-magnification microlensing events have been theoretically anticipated as an important way to discover extrasolar planets. However, only in the last several years have they been firmly established as a crucial venue of microlensing...
