A new image from ESOs APEX instrument shows a cloud of gas and dust in the Orion region. Image credit: ESO
When astronomers see dark regions in nebula in visible light, they know theres something going on. Theres got to be some kind of star forming activity pumping out material that obscures the view to the newly forming starts. Switch to infrared and you can peer through that intervening dust to see the young stars at work.
Astronomers using the European Southern Observatorys Atacama Pathfinder Experiment (APEX) telescope in Chile were surprised to see a dark region in the nebula NGC 1999, even in infrared, when the cause of the dark region should have been apparent.
Ooo, mystery.

Image caption: This image of a Martian rock illuminated by white-light LEDs (light emitting diodes) is part of the first set of nighttime images taken by the Mars Hand Lens Imager (MAHLI) camera at the end of the robotic arm of NASAs Mars rover Curiosity. The image was taken on Jan. 22, 2013, after dark on Sol 165. It covers an area about 1.3 inches by 1 inch (3.4 by 2.5 centimeters). Credit: NASA/JPL-Caltech/MSSS
Curiositys high resolution robotic arm camera has just snapped the 1st set of night time images of a Martian rock of the now 5 1/2 month long mission using illumination from ultraviolet and white light emitting LEDs. See the images above and below.
The Mars Hand Lens Imager (MAHLI) camera is located on the tool turret at the end of Curiositys 7 foot (2.1 m) long robotic arm.
MAHLI took the close-up images of a rock target named Sayunei on Jan. 22 (Sol 165), located near the front-left wheel after the rover had driven over and scuffed the area to break up rocks in an effort to try and expose fresh material, free of obscuring dust.
