Spitzer discovers time-delayed jets around young star

A baby star sprouts two identical jets, seen as green lines emanating from a fuzzy star, in this photograph taken by the Spitzer Space Telescope and released by NASA April 4, 2011. The jet on the right had been seen before in visible-light views, but the jet at left -- the identical twin to the first jet -- could only be seen in detail with Spitzer's infrared detectors. This left jet was hidden behind a dark cloud, which Spitzer can see through. The stars are located approximately 1,400 light-years away in the Orion constellation. [Photo/Agencies]
