ST ScI Preprint #1362 . ... However, the radial extents of some of the very young clusters (ages <10 Myr) are much larger than those of old globular clusters (e.g., the outer radius of Knot S exceeds 450 pc). ... Star clusters around the edge of the dust overlap region appear to be the youngest, with ages 5 Myr, while clusters in the Western Loop appear to be 5-10 Myr old. ... A handful of old globular clusters from the progenitor galaxies are also identified. ...

... Dust in the region is studied photometrically at ultraviolet, optical, and far-infrared wavelengths to analyze nebular colors, grain properties, and scattering geometry. Constraints on this geometry are provided by spectroscopy of radio emission lines and optical absorption lines of the interstellar gas, which also reveal a significant amount of fine-scale filamentary structure. ...

High-Resolution Stereo Camera (HRSC) nadir and color channel data taken during revolution 10,736 on June 6, 2012, by ESAт??s Mars Express have been combined to form a natural-color view of Nereidum Montes. Centered at around 40ТАS and 310ТАE, the image has a ground resolution of about 23m per pixel. ... Undulations in crater floors are commonly seen in mid-latitude regions on Mars and are believed to be a result of glacial movement. ...

... 640W A survey of ultracompact (UC) Hii regions has been carried out by searching for 6.669-GHz methanol maser emission from a sample of 535 IRAS-selected candidates. A total of 201 candidates exhibit methanol emission. These sources have been used, in conjunction with previously identified UC Hii regions, to provide a base for further studies of such regions. ... Methanol maser and/or radio continuum emission is found in 364 cases towards IRAS-selected regions. ...

The solid line is a regression stright line for the main sequence of clusters, and the dotted line parallel to it separates the sequence of clusters of anomalously small mass shown by open triangles. ...

... We report on the preliminary results of experiments using a Bayesian cluster method to cluster objects present in photographic images of the POSS-II. ... We believe that the application of such algorithms to large-scale astronomical sky surveys can aid in cataloging the detected objects, and may even have the potential to discover new categories of objects. ... We have thus started to explore new clustering analysis and unsupervised classification techniques for this task. ...
