   X-ray observation of class 0 protostar, L1157 is proposed. ASCA
   detected X-ray emission from Class I protostars for the first time. The
   origin of the X-ray emission from protostars is very unclear, however,
   the X-ray emission gave us very impotant information about star
   formation, for example about rotaion, and magnetic field. The proposed
   taeget L1157 at a distance of 440pc has well-collimated bipolar
   outflows which cause strong shock-heating of the ambient gas.
