We present an exhaustive quantitative comparison of all the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general behavior of Milky Way extinction curves. ... The near-infrared extinction curves are calculated mainly from 2MASS photometry supplemented with DENIS and new JHK photometry. ... This result strengthens the picture dust extinction curves exhibit of a continuum of properties between those found in the Milky Way and the SMC bar. ...
... Complex astrophysical phenomena could now be studied spectroscopically: the X-ray absorption line forest intrinsic to Seyfert galaxies; the interaction between AGN jets and intracluster media; hot winds of starburst galaxies; stellar coronal plasmas; the charge -exchange emission of Mars' exosphere; the X-ray irradiation of protoplanetary disks; and the myst erious flat-topped spectral line shapes of O star winds. ... We estimate that Gen-X will be able to detect and resolve 20, 000 stars in NGC...
