This image made available by NASA shows fledgling stars hidden in the gas and clouds of the Orion nebula, captured by infrared observations from the Spitzer Space Telescope and the European Space Agency's Herschel mission. In several hundred thousand years, some of the forming stars will accrete enough material to trigger nuclear fusion at their cores. (ESA/NASA/JPL-Caltech/N. Billot (IRAM) via AP)
