      It's a bouncing baby . . . star! Combined observations from NASA's  Spitzer Space Telescope and the newly completed Atacama Large  Millimeter/submillimeter Array (ALMA) in Chile have revealed the throes  of stellar birth as never before in the well-studied object known as HH  46/47. 

  The Spitzer  observations show twin supersonic jets emanating from the central star  that blast away surrounding gas and set it alight into two bubbly lobes.  HH 46/47 happens to sit on the edge of its enveloping cloud in such a  way that the jets pass through two differing cosmic environments. The  rightward jet, heading into the cloud, is plowing through a "wall" of  material, while the leftward jet's path out of the cloud is relatively  unobstructed, passing through less material. This orientation serves  scientists well by offering a handy compare-and-contrast setup for how  the outflows from a developing star interact with their surroundings.
