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.
Light does not have a color but all colors are visible because of it. Elements like fire or other things that produce light all have light as their color. Relating back to the elements, when burned by fire air and water turn black. Such is the burning coals when doused in water. This is Aristotle's explanation of simple colors.
That is, the light of each shell adds to the total amount. Thus the more shells, the more light; and with infinitely many shells, there would be a bright night sky. While dark clouds could obstruct the light, these clouds would heat up, until they were as hot as the stars, and then radiate the same amount of light.
Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchus and well within the Milky Way galaxy at a distance of about 125 parsecs (407 light-years). [2] It is both close and dense enough that stars behind it cannot be seen from Earth.

[1]Upper-atmospheric lightning and ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
