... October 9, 1995 . Saturn's Moon Dione . Credit: NASA , Voyager 1, Copyright Calvin J. Hamilton . Explanation: Dione , one of Saturn 's larger moons, is remarkable for its bright surface streaks. These streaks run across some of Dione's many craters, which indicate that the process which created the streaks occurred later than the process which created the craters. ... Dione was discovered by Giovanni Cassini in 1684. ... Tomorrow's picture: Dione's Lagrange Moon Helene . ...

... 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 | ...

... 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. ...
