... February 1, 1999 . The Subaru Telescope . ... The gray building housing Subaru is visible just left of the white Keck domes near the photo's center. Subaru is the latest in the class of optical telescopes using a mirror with a diameter greater than 8 meters. Subaru's 8.3-meter primary is the largest single-piece optical telescope mirror yet made , and is so thin that its precise shape can be monitored and adjusted. ... About APOD > . ...

... April 12, 1999 . Nearby Spiral Galaxy NGC 4945 . Credit: 2P2 Team , WFI , MPG/ESO 2.2-m Telescope , La Silla , ESO . Explanation: For such a close galaxy, NGC 4945 is easy to miss. NGC 4945 is a spiral galaxy in the Centaurus Group of galaxies, located only six times farther away than the prominent Andromeda Galaxy . ... Therefore galaxy-gazers searching the southern constellation of Centaurus need a telescope to see it. ... About APOD > . ...

... 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. ...
