An article accepted for publication in the journal “Astronomy & Astrophysics” reports an overview of the first results of an astronomical survey called ALCOHOLS concerning the Orion Molecular Cloud Complex. For the occasion, ESO released images of the Orion Flame Nebula, one of the star formation areas within that complex. Researchers led by former ESO astronomer Thomas Stanke used the SuperCam instrument mounted on the APEX radio telescope to map the presence of carbon monoxide in that area. Despite its name and what it looks like in the images, the Flame Nebula is very cold, with temperatures generally just a few degrees above absolute zero.
