M78 (blue nebula in center of image) is a section of the cloud just above Orion’s Belt. This image is a combina-tion of 2 views: one in visible light from the Digitized Sky Survey, and the other from the APEX telescope, which can see light in the submillimeter wave-length range. Only cold/cold objects emit at this wavelength - a few degrees above absolute zero. The cold dust is falsely colored and glows orange. The blue material is gas/dust which can be seen in visible light.
The Fairy of the Eagle Nebula. This image shows one of several striking dust pillars of the Eagle Nebula. This pillar is ten light years tall and spews radiation much hotter than common fire. The greater Eagle Nebula, M16, is a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open cluster of stars.
