... March 21, 1997 . Io's Surface: Under Construction . Credit: The Galileo Project , JPL , NASA . ... Io's surface is constantly under construction . This moon of Jupiter holds the distinction of being the Solar System's most volcanically active body -- its bizarre looking surface continuously formed and reformed by lava flows. ... The notable absence of impact craters suggests that the entire surface is covered with new volcanic deposits much more rapidly than craters are created. ...
... 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. ...
. Attached is an image of the Nova in M32. It was made under uncomfortable conditions, as our summer here in Germany makes a clear sky a rare event. To create this image, 5 images of 45 seconds each were summed. It was taken on September 12, at 21h 45m UT. Udo Zlender - Udo.Zlender@gmd.de . Back to Supernovae in NGC and IC galaxies.

... 2000 January 11 . The Rosette Nebula in Hydrogen, Oxygen, and Sulfur . ... Explanation: The Rosette Nebula is a large emission nebula located 3000 light-years away. The great abundance of hydrogen gas gives NGC 2237 its red color in most photographs . The wind from the open cluster of stars known as NGC 2244 has cleared a hole in the nebula's center. ... Here green light originating from oxygen and blue light originating from sulfur supplements the red from hydrogen. ... 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. ...
