Supernovae in 3-D
Astronomers have finally succeeded in modeling in three dimensions the behavior of a massive star during the final seconds of its life.
Solar Weather Probed in Depth
The global solar image shows average wind speeds for the region just below the stellar surface. The speeds are averages of the weather patterns observed over 14 days in April 2002. Large hurricane-like swirling winds are clearly visible.Courtesy University of Colorado/JILA A new analysis of observations from the Solar and…
