... 2001 April 25 . Space Laser Creates Artificial Star . ... So rather than try to eradicate existing stars with a laser, these astronomers create an artificial star of their own right where they need it -- with a laser . Subsequent observations of the artificial laser guide star can reveal information so detailed about the blurring effects of the Earth's atmosphere that much of this blurring can be removed by rapidly flexing the mirror. ...

... October 16, 1995 . Starburst Galaxy M94 . Credit: NASA , Ultraviolet Imaging Telescope . Explanation: The spiral galaxy M94 is somewhat unusual in that it shows a great ring of bright young stars particularly apparent when observed in ultraviolet light , as shown above. Such a high abundance of these young blue stars may cause a galaxy to be designated a starburst galaxy. ... Tomorrow's picture: Galaxy Dwingeloo 1 Emerges . ... About APOD | ...

XXVIII General Assembly of the IAU, SPS15 Beijing, August 31, 2012 . N.N. Samus, S.V. Antipin "Variable Stars and Data-Intensive Astronomy" . During the 26th IAU General Assembly in Prague, the IAU Division V (Commissions 27 and 42) considered the future of variable-star catalogues. ... To discuss these problems and to look for their solutions, the IAU Commission 27, on behalf of the IAU Division V, created an informal working group, chaired by the GCVS editor, Dr. Nikolai Samus. ...

THE 75th NAME-LIST OF VARIABLE STARS. ... The 75th Name-List consists of two tables. ... the literature, taken from positional catalogues, including USNO A1.0/A2.0 and GSC, or determined by the authors); the range of variability (sometimes the column Min gives, in parentheses, the amplitude of light variation; the symbol ( means that the star , in minimum light, becomes fainter, than the magnitude indicated); and the system of magnitudes used ( P are photographic ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ... Brandt and Blitz (1993) published the distances and radial velocities for a total of 206 H II-regions. ... Astron. ...
