Cluster of High-Mass Young Stellar Objects

https://www.nrao.edu/archives/plugins/Dropbox/files/g19_61-0_23_hi.jpg

Description

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.
