... A Halo for NGC 6164 . ... Explanation: Beautiful emission nebula NGC 6164 was created by a rare, hot, luminous O-type star, some 40 times as massive as the Sun. ... That makes it similar in appearance to more common and familiar planetary nebulae - the gaseous shrouds surrounding dying sun-like stars. ... The gorgeous skyscape is a composite of extensive narrow-band image data, highlighting glowing atomic hydrogen gas in red and oxygen in blue hues, with broad-band data for the surrounding starfield...
... April 9, 1999 . WR 104: Pinwheel Star . ... Explanation: Like a cosmic lawn sprinkler, dust streaming from a rotating star system creates a pinwheel pattern in this false color infrared image . Astronomers discovered the surprising star dust scenario using a sophisticated interferometer and the 10 meter Keck I telescope to observe the bright Wolf-Rayet star WR 104. ... The problem is, their starlight would also be so intense that any dust flakes should be destroyed! ... 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. ...

... Here is a brief outline of the current theory of the events in the early history of the solar system: . A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. ... The gas cools off enough for the metal, rock and (far enough from the forming star) ice to condense out into tiny particles. (i.e. some of the gas turns back into dust). ... Once the larger of these particles get big enough to have a nontrivial gravity, their growth accelerates. ...
... 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. ...
