English: This image from the VISTA infrared survey telescope at ESO’s Paranal Observatory in northern Chile is part of the largest infrared high-resolution mosaic of Orion ever created. It covers the Orion A molecular cloud, the nearest known massive star factory, lying about 1350 light-years from Earth, and reveals many young stars and other objects normally buried deep inside the dusty clouds.
