| Orion Nebula Cluster: Cluster of young stars in the Orion Nebula. 
 
 Caption: These Chandra images show the central region of the Orion Nebula, one of the closest star-forming regions to Earth. Assembled into a time-lapse movie, these observations show that, over the course of mere hours, many of the 700 objects in the field appear to "shimmer" or vary, in X-ray intensity. This flaring behavior appears to be a common characteristic of young stars. Since the Sun formed in a similar region long ago, this discovery may help us better understand how our solar system formed.
 
 Scale: Image is 30 arcmin top to bottom.
