Infrared dark cloud

They can be seen in silhouette against the bright diffuse mid-infrared emission from the galactic plane.

[1][2] Infrared dark clouds have only been recently discovered in 1996 using the ISO[3] and therefore are in need of further research.

[4] The Spitzer Space telescope, created by NASA to detect infrared radiation,[5] assisted in the location and identification of infrared dark clouds.

The highly sensitive telescope was used to analyze the Milky Way and create numerous astronomical surveys at wavelengths that allowed for the detailed analysis of IRDCs.

Through the use of convolutional neural networks,[6] an IRDC catalog consisting of 18,845 items was created by two astronomers named Jyothish Pari and Joe Hora, who created a computer algorithm which could efficiently scan the images created by the Spitzer telescope’s IRAC camera to find infrared dark clouds.
