In this image of the Orion nebula, the VISTA telescope turned its infrared vision upon the young stars emerging in and around the visible cloud of gas enshrouding the stellar nursery. A red region directly above the center of the image reveals young stars that continue to form amidst clouds of interstellar gas. Such stars can eject gas at speeds of almost 435,000 miles per hour (700,000 km/hr).
