... December 7, 1998 . Star-Forming Region RCW38 . ... Explanation: Star cluster RCW38 was hiding. This open cluster of stars is located about 5000 light years away towards the constellation of Vela . ... The reason is that the open cluster is so young that it is still shrouded in thick dust that absorbs visible light. ... When viewed in infrared light , however, the star cluster in RCW38 is revealed, because dust is less effective at absorbing infrared light. ... 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. ...
... 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. ...
