Two identical jets (green) sprout from either side of a budding star in a new infrared picture from NASA's Spitzer Space Telescope released April 4.The jets are ejecting knots of gas and dust from a sphere of material surrounding the still-forming star. Spitzer's data helped astronomers figure out that one jet spurts material from the sphere 4.5 years before its counterpart, an unexpected discovery that may shed light on the process of star formation.
