The detection of terrestrial-sized extrasolar planets from the ground has been thought to be virtually impossible due to atmospheric scintillation limits. However, we show that this is not the case for specially selected (but nevertheless main sequence) stars, namely small eclipsing binaries. For the smallest of these systems, CM Draconis, several

I discuss new observations of circumnuclear regions in barred galaxies, both of their kinematics and their near-infrared (NIR) morphology. New kinematic observations of M100 confirm that (1) the inner bar-like feature detected before in this galaxy is in fact a continuation of the large-scale stellar bar; and (2) the spiral arm-like sites of star

We have used the Nordic Optical and the William Herschel Telescopes to obtain images and long-slit spectra of Cygnus A under conditions of sub-arcsecond seeing. The high spatial resolution and accurate positional information obtained from a comparison between the images and spectra allow us to study in detail the kinematics and excitation of the
