Astronomy: Starbursts near and far

Observations of intensely bright star-forming galaxies both close by and in the far Universe seem to emphasize their similarities. But look a little closer, and telling differences emerge.

In a recent issue of the Astrophysical Journal, two papers1, 2 present the latest measurements of 'starburst' galaxies — galaxies whose extreme brightness is thought to indicate short, intense bursts of star formation. This latest work is a fine example of the instruments and methods that are providing ever deeper insight into these spectacular objects.
