... 2006 September 5 . Bright Cliffs Across Saturn's Moon Dione . Credit: Cassini Imaging Team , SSI , JPL , ESA , NASA . Explanation: What causes the bright streaks on Dione? Recent images of this unusual moon by the robot Cassini spacecraft now orbiting Saturn are helping to crack the mystery. ... The bright ice-cliffs run across some of Dione 's many craters, indicating that the process that created them occurred later than the impacts that created those craters. ... About APOD | ...
... October 16, 1995 . Starburst Galaxy M94 . Credit: NASA , Ultraviolet Imaging Telescope . Explanation: The spiralgalaxy 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. ...

... 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. ...
