Cluster of High-Mass Young Stellar Objects

Combining VLA 8 GHz continuum emission data from the archive, taken over the past ~15 years by different observing groups, we have found the G19.61-0.23 region to contain more than 9 ultra-compact H-II regions of gas ionized by massive young stars. This image clearly shows that high-mass stars form in clusters.

The white contour indicate the 10-sigma level of the image noise level.
