A striking example is M101, shown above , whose relatively close distance of about 22 million light years allow it to be studied in some detail. ... One result is that M101 , also called the Pinwheel Galaxy , has several extremely bright star-forming regions (called HII regions ) spread across its spiral arms. ... About APOD | ...

... October 27, 1999 . In the Heart of the Tarantula Nebula . Credit: Gary Bernstein Megan Novicki ( U. Michigan ); . ... Explanation: In the heart of monstrous Tarantula Nebula lies one of the most unusual star clusters. ... The energetic light from these stars continually ionizes nebula gas, while their energetic particle wind blows bubbles and defines intricate filaments. ... In the heart of this heart is a central knot of stars that is so dense it was once thought to be a single star. ...

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 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. ...
