An image by the Spitzer telescope of stars in WL 20 (left). An expanded view of the twin stars with matching jets streaming into space from their north and south poles in the artist’s illustration on the right. The stars appear to have pushed away the billowy orange clouds within which they formed, suggesting their birth processes are nearing completion. (Image credit: U.S. NSF/ NSF NRAO/B.
