... Our main goal was to study the large-scale distribution of the molecular gas in the Serpens region and to understand its relation with the denser gas in the cloud cores, previously studied at high angular resolution. ... The 13CO and C18O(1--0) maps of the centroid velocity show an increasing, smooth gradient in velocity from East to West, which we think may be caused by a global rotation of the Serpens molecular cloud whose rotation axis is roughly aligned in the SN direction. ...

How Do Children Learn? ... Here we propose an innovative approach to children's learning, one that integrates the transmission, constructivism, and social constructivism models by having teachers present some of the fundamental concepts involved in astronomy education at the elementary level. ... learn the story . ... Before presenting sample stories and curricular ideas, we must discuss some of the impediments, pedagogical and professional, to teaching and learning astronomy at the elementary level. ...

... The circumnuclear GASEOUS disks are often decoupled from the circumnuclear stellar disks and are even stronger inclined to the outer disk planes; in fact, we have found a considerable `population' of inner polar rings. Inner gas polar rings are found as in spiral galaxies with the massive outer gas disks co-planar to the main symmetry planes (e.g. NGC 2841, Sil'chenko et al. 1997, and NGC 7217, Sil'chenko & Afanasiev 2000) as well in many lenticular galaxies (Fig. ...
