This young star hasn't started the nuclear fusion yet and obtains its energy still from the collapse of its birth cloud. It emits two opponent jets, each three quarters of a light-year long. Those have just recently broke through the surrounding cloud. L1157 is orbited by a disk of matter, which once could form a planetary system. It is the first star to be discovered in this state of stellar evolution.
