... Hubble Detects Faster-Than-Light Motion in Galaxy M87 . ... Click on image for larger version. (100kB GIF) Sequence of Hubble images showing apparent motion at six times the speed of light in the galaxy M87. ... The slanting lines track the moving features, and the speeds are given in units of the velocity of light ``c." The images were made between 1994 and 1998 with the Faint Object Camera on the Hubble Space Telescope. ... PHOTO CREDIT: John Biretta, Space Telescope Science Institute. ...
... 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...
