An extreme example of visible light extinction, caused by a dark nebula. In astronomy, extinction is the absorption and scattering of electromagnetic radiation by dust and gas between an emitting astronomical object and the observer. Interstellar extinction was first documented as such in 1930 by Robert Julius Trumpler.
Dark nebulae are dark because naked interstellar dust or dust covered with condensed gases absorb visible light by extinction and remit infrared and submillimetre radiation. Infrared emission from the dust cools the clouds down to 10 to 20 K. [ 63 ] The largest dark nebula are giant molecular clouds that contain 10 thousand to 10 million solar ...
Interstellar gas was further confirmed by Slipher in 1909, and then by 1912 interstellar dust was confirmed by Slipher. [27] Interstellar sodium was detected by Mary Lea Heger in 1919 through the observation of stationary absorption from the atom's "D" lines at 589.0 and 589.6 nanometres towards Delta Orionis and Beta Scorpii.

Interstellar is a 2014 epic science fiction drama film directed by Christopher Nolan, ... humanity faces extinction due to dust storms and widespread crop blights.
Solar System dust includes comet dust, planetary dust (like from Mars), [4] asteroidal dust, dust from the Kuiper belt, and interstellar dust passing through the Solar System. Thousands of tons of cosmic dust are estimated to reach Earth's surface every year, [ 5 ] with most grains having a mass between 10 −16 kg (0.1 pg) and 10 −4 kg (0.1 ...

The extinction of the light is caused by interstellar dust grains in the coldest, densest parts of molecular clouds. Clusters and large complexes of dark nebulae are associated with Giant Molecular Clouds. Isolated small dark nebulae are called Bok globules.
