... November 17, 1998 . NGC 7635: The Bubble Nebula . ... A massive star that is not only bright and blue, but also emitting a fast stellar wind of ionized gas . The Bubble Nebula is actually the smallest of three bubbles surrounding massive star BD+602522 , and part of gigantic bubble network S162 created with the help of other massive stars. ... The Bubble Nebula , also known as NGC 7635, is about 10 light-years across and visible with a small telescope towards the constellation of Cassiopeia . ...

... April 9, 1999 . WR 104: Pinwheel Star . ... Explanation: Like a cosmic lawn sprinkler, dust streaming from a rotating star system creates a pinwheel pattern in this false color infrared image . Astronomers discovered the surprising star dust scenario using a sophisticated interferometer and the 10 meter Keck I telescope to observe the bright Wolf-Rayet star WR 104. ... The problem is, their starlight would also be so intense that any dust flakes should be destroyed! ... About APOD > . ...

... 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. ...
