A radio interferometer array in space providing high dynamic range images with unprecedented angular resolution over the broad frequency range from 0.03 - 30 MHz will open new vistas in solar, terrestrial, galactic, and extragalactic astrophysics. The ALFA interferometer will image and track transient disturbances in the solar corona and

STEPHI is a photometry network that aims to obtain data to reach a better understanding of the physics of stellar interiors by seismology of δ Scuti stars. For ten years now STEPHI has been harvesting multisite rapid photometry data of δ Scuti stars on the main sequence. With 12 δ Scuti stars observed during three-week, three-site campaigns, STEPHI

Symbiotic Miras give a nice practical demonstration of the formation of bipolar and highly aspherical nebulae as a consequence of interaction in detached binaries. We believe that these binary systems are among the most promising candidates for the progenitors of bipolar planetary nebulae. We present a list of the optically extended nebulae known
