Astronomers Simulate Life And Death In The Universe (11/1/2007)

Stars always evolve in the universe in large groups, known as clusters. Astronomers distinguish these formations by their age and size. The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations. The scientists have solved -- at least at a theoretical level -- one of the oldest astronomical puzzles, namely the question of whether star clusters differ in their internal structure. ...> Full Article

The Frugal Cosmic Ant (9/28/2007)

Using ESO's Very Large Telescope Interferometer and its unique ability to see small details, astronomers have uncovered a flat, nearly edge-on disc of silicates in the heart of the magnificent Ant Nebula. The disc seems, however, too 'skinny' to explain how the nebula got its intriguing ant-like shape. ...> Full Article
