The problem of eXtremely-Metal Deficient (XMD) galaxy ages. ... Problem of ages of XMD galaxies is addressed through the comparison of colours of stars in their outer regions (where one can neglect the effect of recent star-formation activity), with model tracks of evolving stellar populations from, e.g., the popular package PEGASE.2 (Fioc Rocca-Volmerange 1999). For some of XMD galaxies, the contribution of nebular emission in the light of outer regions is negligible or invisible. ...

... the radiative transfer equation (RTE) for the randomly-irregular magnetized plasma has been derived on the base of general grounds of the multiple scattering theory . ... Solutions of several absolute tasks of the scattering theory have been obtained (on the optical depth of the ionospheric plasma layer, on the value of radio wave anomalous attenuation, on anomalous refraction, on the backscattered signal intensity for the source being placed within a plasma layer). ...

Next: ZGSC (Compressed GSC) and XSKYMAP . ... This is a preliminary report on an investigation of the quality and properties of plates digitized during creation of the Guide Star Catalog (GSC). The results will be vital for reclassifying GSC objects. ... Many objects are measured on more than one plate, and thus have multiple catalog entries. ... Among the shortcomings of the GSC are: biased magnitudes and incorrect classifications for certain objects, presence of artifact objects. ...

... Here we discuss our survey methods, identification procedure and first results. Our survey is found to be efficient at finding flat-spectrum radio-loud quasars (FSRQs, 59 of our first 85 IDs) and BL Lacertae objects (22 of our first 85 IDs), a figure which is comparable to or greater than that achieved by other radio and X-ray survey techniques. ... Particularly important is the identification of a large population of FSRQs ( of DXRBS FSRQs) with ratios of X-ray to radio luminosity . ... FSRQs . ...

The night after the John Glenn program, I pitched the terraforming idea to my students. I asked them if they'd like to terraform Mars as a big class project; I wanted to throw the idea to them and see how they would react. Already I had a vision of splitting the class into several groups and having each group take charge of a portion of the project. ... Following my initial idea on how to conduct the project, I split the class into six groups, each student choosing his or her group. ...
