The measurement of coronal fields has in the past generally been restricted to the field strength or to only some of the components of the magnetic vector. We present here a technique for measuring the full magnetic vector near the base of the solar corona. As an application we report on observations of a developing active region with ongoing

Recent results from Hubble Space Telescope (HST) have resolved starbursts as collections of small young stellar clusters. We have elaborated tep{Melo04} a photometric catalogue of the young stellar clusters in the nuclear starburst of M82, observed with the HST WFPC2 in Hα (F656N) and continuum images. We identify 198 young super stellar clusters

Super star clusters (M ecl > 105 M sun) are the largest stellar nurseries in our local Universe, containing hundreds of thousands to millions of young stars within a few light years. Many of these systems are found in external galaxies, especially in pairs of interacting galaxies, and in some dwarf galaxies, but relatively few in disk galaxies like

Context: NRAO 150, a compact and bright radio to mm source showing core/jet structure, has been recently identified as a quasar at redshift z = 1.52 through a near-IR spectral observation. Aims: To study the jet kinematics on the smallest accessible scales and to compute the first estimates of its basic physical properties. Methods: We have
