Very young stars cannot be seen in the visible light spectrum. But ESO's VISTA telescope in Chile - the largest in the world dedicated to surveying the heavens - pierced the dust that shrouds them by zeroing in on infrared wavelengths. The new image survey "allows the earliest evolutionary phases of young stars within nearby molecular clouds to be systematically studied," ESO said in a statement. The project has so far identified nearly 800,000 new stars, young "stellar objects" and distant galaxies. The Orion nebula, visible with the naked eye in the night sky, was first scientifically described in the early 17th century. In 1789, British astronomer William Herschel - using a home-made two-metre (six-foot) telescope - prophetically described nebula such as Orion as "the chaotic material of future Suns."
