Scientific literacy in our society has entered a period of serious decline. Contrary to our perception, the interest of lay people for the sciences has not grown in parallel with the advances that science has brought to society. Advanced communitites are starting to feel the shortage of bright scientists. In what follows I will try to examine the

Spectroscopic observations obtained with the VLT of one planetary nebula (PN) in Sextans A and of five PNe in Sextans A and of several H ii regions in these two dwarf irregular galaxies are presented. The extended spectral coverage, from 320.0 to 1000.0 nm, and the large telescope aperture allowed us to detect a number of emission lines, covering

Realistic solar magneto-convection simulations including the photospheric layers are used to study the polarization of the Fe i Zeeman-sensitive spectral lines at 6301.5, 6302.5, 15 648 and 15 652 Å. The Stokes spectra are synthesized in a series of snapshots with a mixed-polarity magnetic field whose average unsigned strength varies from B > = 10

Table main gives the names, coordinates (J2000), epoch, proper motions, and optical (BjRI) and near-infrared (JHKs) magnitudes for new, red proper motion objects published in this paper. Table obslog1 provides the observing logs for a subset of proper motion objects observed photometrically with FORS1 and ISAAC on the VLT. It includes observing

The site survey for the Advanced Technology Solar Telescope concluded recently after more than 2 years of data gathering and analysis. Six locations, including lake, island, and continental sites, were thoroughly probed for image quality and sky brightness. The present paper describes the analysis methodology employed to determine the height
